Description: This perennial herbaceous plant is 2½–4' tall at maturity. It has a branched bushy shape above, but it is unbranched below. The root system often sends up more than one shoot; each shoot develops into a separate plant. The central stem of each plant is unbranched and naked below (to about 1' above the ground), but branched above; it is relatively stout, light green to gray, terete, glabrous, and usually glaucous. The widely spreading to ascending lateral stems have similar characteristics, except they are more slender. As a general rule, both the central stem and lateral stems become more gray and glaucous with age. Alternate trifoliate leaves occur along the lateral stems and upper stem where it branches. Individual leaflets are 1.5–4 cm. long and 0.8–2 cm. across; their size can vary significantly depending on the characteristics of the parent species and their relative dominance in genetic expression. Individual leaflets are oblanceolate to obovate in shape, while their margins are toothless and often revolute (folded downward). The leaflet bases are wedge-shaped (cuneate), while their tips are more or less rounded. Young leaflets are medium green and glabrous, but with age they become bluish green or grayish green on their upper surface and whitened on their lower surface. A reticulated network of fine veins is visible on the whitened lower surface of older leaves. The petioles of lower to middle trifoliate leaves are 4-8 mm. long, while the upper trifoliate leaves are nearly sessile. The petioles are light green to gray, slender, and finely grooved above. The petiolules of the terminal leaflets are very short (about 1 mm. in length), while the lateral leaflets are almost sessile. The central stem terminates in a spike-like raceme of flowers about 1' long, while the upper lateral stems terminate in spike-like racemes of flowers about 4-8" long. These racemes are usually erect, although some of the lateral racemes may be ascending. The flowers are distributed somewhat loosely along these racemes, facing in all directions. The central stalks (rachises and peduncles) of these racemes are grayish green to gray, terete, glabrous, and usually glaucous. Each flower is about ¾" long, ½" tall, and ½" across, consisting of 5 yellow petals, a grayish green to gray short-tubular calyx, 10 inserted stamens, and a pistil. [图片]The petals are arranged in a typical pea-like floral structure, consisting of an upright banner and a forward-projecting pair of wings covering an interior keel. The lateral margins of the banner are curved away from the face of the flower, and the base of the banner may have a few small purplish splotches. The calyx is somewhat 2-lipped: its lower lip has 3 deltate-ovate teeth, while its upper lip is more or less convexly rounded. The slightly ascending pedicels of the flowers are 4-7 mm. long, slender, grayish green to gray, and glabrous. During the flower bud stage, there are also solitary floral bracts extending below the pedicels. These floral bracts are about the same length as the pedicels, linear-lanceolate in shape, and early-deciduous. The blooming period occurs from late spring to mid-summer, lasting about 3-4 weeks. There is no noticeable floral scent. Afterwards, fertile flowers are replaced by seedpods. [图片]Mature seedpods are ¾" long, ½" across, obovoid-oblongoid in shape, somewhat inflated, and black; they are usually tapering in the front and abruptly rounded in the back. Each seedpod has a long slender stipe (about ½" long) that is straight and a short slender beak (about ¼" long) that is often somewhat curved. The walls of the mature pod are thin but firm; its usually contains a few seeds, otherwise it is hollow. The root system has thick rhizomes that are reddish brown and somewhat woody, from which more than one clonal plant can develop. Cultivation: The preference is full to partial sun, mesic to dry conditions, and sandy loam, although heavier soils and the presence of gravel or rocky material is tolerated if drainage is good. Once danger of frost has passed, growth and development of an established plant is rapid. After the blooming period, this plant continues to grow, but at a much slower pace. This hybrid plant is adaptable to sunny situations, relatively long-lived, and easy to cultivate. [图片]Range & Habitat: The native Deam's Wild Indigo is rare in Illinois, occurring as a natural hybrid in a single county (Kankakee County); see Distribution Map. It has also been found in a single county in NW Indiana, where it is also rare. In Illinois, Deam's Wild Indigo occurs in a sandy savanna and a sand prairie, where its two parent species, Baptisia alba macrophylla (White Wild Indigo) and Baptisia tinctoria (Yellow Wild Indigo), are also present. This hybrid species occurs in high quality natural areas that are usually sandy. Like other Baptisia spp. (Wild Indigo species), it probably benefits from occasional wildfires. [图片]Faunal Associations: Various insects and their larvae feed on Baptisia spp. (Wild Indigo species). These species include the seed-eating larvae of a weevil (Apion rostrum), leaf-mining larvae of leaf beetles (Pachybrachis luridus, Pachybrachis trinotatus), seed-eating broad-headed bugs (Alydus conspersus, Alydus eurinus, Alydus pilosulus, Megalotomus quinquespinosus), leaf-mining larvae of a fly (Liriomyza baptisiae), larvae of the skippers Achalarus lyciades (Hoary Edge) and Erynnis baptisiae (Wild Indigo Duskywing), larvae of the butterfly Callophrys irus (Frosted Elfin), larvae of the Pyralid moths Pococera baptisiella (Wild Indigo Webworm Moth) and Sitochroa dasconalis (Pearly Indigo Borer Moth), larvae of the Tortricid moth Grapholita tristrigana (Three-lined Grapholita), and the oligophagous Neohydatothrips baptisiae (Wild Indigo Thrips); see Panzer et al. (2006), Clark et al. (2004), Bouseman et al. (2006), Bouseman & Sternburg (2001), Schaefer (1980), and Spencer & Steyskal (1986). Mammalian herbivores avoid consumption of Wild Indigo foliage because it is toxic to them. Photographic Location: The wildflower garden of the webmaster in Urbana, Illinois. [图片]Comments: There is some disagreement among taxonomists regarding the classification of this hybrid plant. The ITIS and USDA, for example, consider Baptisia × deamii (Deam's Wild Indigo) to be a junior synonym of Baptisia × serenae (Serene Wild Indigo), which was originally described as a distinct species (Baptisia serenae) occurring along the SE coast of the United States. This view has been rejected because Baptisia × serenae is now widely considered a hybrid between Baptisia albescens (Spiked Wild Indigo) and Baptisia tinctoria (Yellow Wild Indigo), while Baptisia × deamii is considered a hybrid between Baptisia alba macrophylla (White Wild Indigo) and Baptisia tinctoria (Yellow Wild Indigo). This latter viewpoint is consistent with BONAP and Mohlenbrock (2014). Because both Baptisia alba macrophylla and Baptisia tinctoria have relatively broad ranges in the eastern United States and they are somewhat variable, specimens of Deam's Wild Indigo may exhibit significant variation in the size, shape, and hairiness of its leaves (if they are present, such hairs are restricted to the lower leaf surfaces). Deam's Wild Indigo can be readily distinguished from White Wild Indigo by its yellow flowers and usually smaller leaves, and it can be distinguished from Yellow Wild Indigo by its longer racemes (easily exceeding 4" in length), lack of branching on the lower central stem, and usually slightly larger leaves. Serene Wild Indigo, which is not found in Illinois, can be distinguished by the more cylindrical shape and reddish brown to purplish brown color of its mature seedpods.

Description: This perennial plant is up to 1½' tall and 3' across. One or more stems originate from the root system of each plant; these stems branch occasionally and they are ascending to widely spreading. The stems are light green to light purple and terete; for var. bracteata they are either pubescent or hairy, while for var. glabrescens they are glabrous. Alternate trifoliate leaves occur at intervals along these stems. Individual leaflets are 1–3" long and ½–1" across; they are usually oblanceolate in shape, but sometimes they are broadly elliptic or rhombic-elliptic. Leaf margins are smooth (entire). The leaf surfaces are grayish green; for var. bracteata they are appressed-hairy, while for var. glabrescens they are glabrous (Mohlenbrock, 2002). Leaf venation is pinnate. The trifoliate leaves are usually sessile or nearly so; less often, they have pedicels up to 1½" long. At the base of each trifoliate leaf (or its pedicel), there is a pair of leafy stipules; sometimes these stipules are early-deciduous and absent. These stipules can be highly variable in size (less than ¼" to 1½" long); they are sessile and usually lanceolate in shape with smooth margins. Like the leaflets, the stipules are grayish green and appressed hairy to glabrous, depending on the variety. The upper and outer stems of this plant often terminate in racemes of flowers about 3-9" long. These racemes are widely spreading and they are either held above the ground or they sprawl across it. The pedicellate flowers of these racemes face upward toward the light. [图片]Individual flowers are about 1" long and a little less across; they have a typical pea-like floral structure consisting of an upright banner (1 petal) and a pair of wings (2 petals) that enclose the keel (2 petals). These petals are white to pale yellow (more or less cream-colored) and hairless. In addition to a corolla consisting of 5 petals, each flower has a short-tubular calyx with 4-5 triangular teeth, 10 stamens, and a pistil with a single style. The calyx is light green to light purple and less than ½" long; depending on the variety of this plant, it is either appressed-hairy or glabrous. The pedicels of the flowers are about ¾–1½" long, light green to light purple, and either hairy or glabrous. At the bases of these pedicels, there occurs solitary floral bracts that are about ½–1" long, lanceolate in shape, smooth along their margins, and sessile; they are similar to the stipules. The blooming period occurs during mid- to late spring for about 3 weeks. Afterwards, fertile flowers are replaced by seedpods that are 1-2" long, short-oblongoid in shape, slightly flattened, and mostly hollow inside. These seedpods have conspicuous beaks at their tips. Immature seedpods are light green and short-pubescent to glabrous; they become black at maturity. Later in the year, an entire plant may break off at its base, and roll around in the wind as a means of dispersing its seeds. Each seedpod divides into 2 parts to release its seeds; typically there are 5-20 seeds per seedpod. Individual seeds are about 4 mm. long, light brown to black, reniform (kidney-shaped), and glabrous. The root system consists of a stout taproot. Cultivation: The preference is full sun, mesic to dry conditions, and soil containing some sand or loam. Cream Wild Indigo prefers open areas where there is reduced competition from taller vegetation. While it is possible to cultivate this plant in the garden using seeds or transplants, it develops slowly as most vegetative growth occurs during the cool weather of spring after the danger of hard frost has passed. Mature plants can be difficult to transplant because of their deep taproots. Range & Habitat: The native Cream Wild Indigo occurs in scattered locations throughout Illinois (see Distribution Map), but it is uncommon, except at high quality sites. The typical variety, Baptisia bracteata bracteata, is more common in Illinois than Baptisia bracteata glabrescens. Natural habitats include mesic to dry black soil prairies, sand prairies, cemetery prairies, railroad prairies, open rocky woodlands, and sandy savannas. Occasional wildfires are beneficial in maintaining populations of this plant. [图片]Faunal Associations: This plant is cross-pollinated primarily by queen bumblebees after they emerge from hibernation during the spring. Worker bumblebees appear somewhat later. Other long-tongued bees that have been observed to visit the flowers include a digger bee (Synhalonia speciosa) and mason bee (Osmia bucephala bucephala). These insects usually seek nectar from the flowers, although they sometimes collect pollen (Robertson, 1929). Other insects feed on the leaves, seeds, and other parts of Cream Wild Indigo and other Baptisia spp. These species include the larvae of such skippers as the Wild Indigo Duskywing (Erynnis baptisiae) and Hoary Edge (Achalarus lyciades), the larvae of such moths as the Three-lined Grapholita (Grapholita tristrigana) and Black-spotted Prominent (Dasylophia anguina), and the larvae of such butterflies as the Frosted Elfin (Callophrys irus), Orange Sulphur (Colias eurytheme), and Marine Blue (Leptotes marina); see Bouseman et al. (2006), Miller (1987), Wagner (2005), and Bouseman & Sternburg (2001). Another insect feeder is the Wild Indigo Weevil (Apion rostrum); the adults feed destructively on the flowers and leaves, while the larvae feed on the seeds (Sauer, 2005). Other insects that use Cream Wild Indigo and other Baptisia spp. as host plants include a leaf beetle (Pachybrachis luridus), seed-eating broad-headed bugs (Alydus spp.), oligophagous thrips (Neohydatothrips baptisiae), Keeler's Grasshopper (Melanoplus keeleri luridus), and other grasshoppers (Melanoplus spp., etc.); see Clark et al. (2004), Schaefer (1980), Stannard (1968), and Campbell et al. (1974). Cream Wild Indigo is not normally bothered by mammalian herbivores because its foliage is toxic. When horses and cattle eat sufficient quantities of this plant, as well as other Baptisia spp. that may be present, they can become seriously poisoned. [图片]Photographic Location: The photographs were taken at the Loda Cemetery Prairie in Iroquois County, Illinois. The photographed plants are the typical variety of Cream Wild Indigo. Comments: This is one of the earliest plants to bloom in the prairie, and it is quite showy and attractive. With the exception of the Blue Wild Indigo (Baptisia australis), other Baptisia spp. that occur in Illinois bloom later in the year. This latter species is rare in natural areas of the state, although it is relatively common in cultivation because of the showy blue flowers. Another species, White Wild Indigo (Baptisia alba macrophylla), is a taller plant with white flowers. It differs from Cream Wild Indigo by having erect racemes of flowers, rather than racemes that are widely spreading or sprawl across the ground. The foliage of this latter species is glabrous. Yellow Wild Indigo (Baptisia tinctoria) is also rare in natural areas of the state, occurring in sand prairies and sandy savannas in Kankakee County. This species is about the same height as Cream Wild Indigo, but its flowers are smaller in size and more yellow, while its foliage is glabrous. Unlike the preceding species of this genus, Yellow Wild Indigo doesn't produce flowers in elongated racemes. Another scientific name of Cream Wild Indigo is Baptisia leucophaea.

Description: This herbaceous perennial plant sends up one or more leafy stems (usually several) that branch abundantly, forming a bushy appearance. The stems are light green or whitish green, terete, glabrous, and sometimes glaucous. Alternate trifoliate leaves occur along the entire length of each stem, changing little in size. Their leaflets are ¾–1½" long and about one-half to one-third as much across; they are oblanceolate to obovate in shape and entire (toothless) along their margins. The leaflet bottoms are wedge-shaped (cuneate), while their tips are more rounded and blunt. The upper and lower leaflet surfaces are grayish green, medium green, or bluish green; they are glabrous. The leaflets have prominent central veins; their surfaces are more or less inclined (angled upward) along both sides of these veins. The leaflets are sessile or nearly so. The petioles of the trifoliate leaves are up to ½" long; they are light green and glabrous. At the bases of petioles, there are pairs of leafy stipules. Individual stipules are up to ¾" long, although they are typically about ¼" long. The stipules are linear-lanceolate to oblong-lanceolate in shape and entire along their margins. The upper stems terminate in erect racemes of flowers about ½–1½' long; the flowers are moderately distributed along these racemes. The central stalks of these racemes are light green or whitish green, terete, glabrous, and sometimes glaucous. Each flower is about 1" long, consisting of a tubular calyx with 4-5 short teeth, a corolla consisting of 5 petals, 10 stamens, and a pistil with a single style. The calyx is light green or grayish green and glabrous; it is shorter than the corolla. The corolla is pale blue to dark blue; it has a typical pea-like floral structure, consisting of an upright banner and a pair of forward-projecting wings that enclose a keel containing the reproductive organs. The slender pedicels of the flowers are up to ½" long and ascending; at the bases of these pedicels, there are solitary leafy bracts up to 1¼" long that are linear-lanceolate in shape and early-deciduous. The blooming period occurs during mid- to late spring for about 3 weeks. There is no noticeable floral scent. Afterwards, fertile flowers are replaced by inflated glabrous seedpods that become up to 2½" long and ¾" across. These seedpods are short-oblongoid in shape with slender beaked tips. Immature seedpods are light green or grayish green, but they become black at maturity, when they split in two to release their seeds. Each healthy seedpod contains 25-50 seeds, although fewer seeds may occur because of predation or adverse weather conditions. Individual seeds are 2–2.5 mm. long, kidney-shaped (reniform), and light to dark brown. The root system consists of a branching taproot that often forms clonal offsets. Cultivation: The preference is full sun, mesic to dry conditions, and a slightly acidic soil that is gravelly or rocky. Blue Wild Indigo readily adapts to fertile loamy soil in gardens, but in naturalistic settings it may have difficulty competing with other plants. Blue Wild Indigo is somewhat slow in becoming established, but it is not difficult to cultivate. Once this plant becomes established, it is very tolerant of drought and long-lived. Like many other legumes, its root system binds nitrogen to the soil via symbiotic bacteria. Range & Habitat: Blue Wild Indigo may be native to NE Illinois in the Chicago area, or it could be a horticultural escape (see Distribution Map). In either case, this plant is extremely rare, and perhaps extirpated from the state as wild populations have not been observed in many years. The primary range of Blue Wild Indigo extends northward to the Ohio River, although isolated populations of this plant have been found further to the north in several states. A dwarf variety of this species also occurs further to the west. Habitats include rocky open woodlands, gravel prairies, and rocky banks of rivers. Occasional wildfires are probably beneficial in maintaining populations of this plant by reducing competition from woody vegetation [图片]Faunal Associations: Queen bumblebees are the primary pollinators of the flowers, where they feed on nectar primarily. Other insects feed destructively on the leaves, developing seeds, and other parts of Blue Wild Indigo and other Wild Indigos (Baptisia spp.). These species include larvae of two moths, the Three-lined Grapholita (Grapholita tristrigana) and Black-rimmed Prominent (Dasylophia anguina), larvae of two skippers, the Wild Indigo Duskywing (Erynnis baptisiae) and Hoary Edge (Achalarus lyciades), and larvae of three butterflies, the Frosted Elfin (Callophrys irus), Marine Blue (Leptotes marina), and Orange Sulfur (Colias eurytheme); see Miller (1987), Covell (1984/2005), Bouseman et al. (2006), and Bouseman & Sternburg (2001). Other insect feeders include the Wild Indigo Weevil (Apion rostrum) and another weevil (Tychius sordidus). The larvae of these weevils feed on the developing seeds, while the adults feed on the leaves and flowers. The Ash-Gray Blister Beetle (Epicauta fabricii) feeds on the flowers and young seed pods, while two leaf beetles, Pachybrachis luridus and Pachybrachis trinotatus, feed on the leaves of Wild Indigos. The Lupine Bug (Megalotomus quinquespinosus) and other broad-headed bugs (Alydus spp.) feed on the seeds. The thrips, Neohydatothrips baptisiae, also uses these plants as sources of food. See Sauer (2005), Evans et al. (1989), Clark et al. (2004), Schaeffer (1980), and Stannard (1968) for more information. Mammalian herbivores usually avoid the consumption of Blue Wild Indigo and other Wild Indigos because their foliage is somewhat toxic. [图片]Photographic Location: The above photographs were taken from the webmaster's wildflower garden in Urbana, Illinois. Comments: This is a favorite garden plant because of its showy flowers and attractive foliage. There is a dwarf variety of Blue Wild Indigo, Baptisia australis minor, that occurs in prairies of the southern and central Great Plains. This variety is smaller in overall size, but it has slightly larger fragrant flowers. Sometimes this variety is classified as a distinct species, Baptisia minor. Both the typical variety and the dwarf variety have blue flowers. Other Wild Indigos (Baptisia spp.) can be distinguished by their differently colored flowers, varying from white to yellow. There are also some differences in the characteristics of their leaves, stipules, inflorescences, and growth form, making them fairly easy to differentiate. Lupines (Lupinus spp.) can be distinguished from Wild Indigos by the greater number of leaflets (more than 3) in their palmately compound leaves. Another interesting difference is the lack of nectaries in the flowers of lupines.

Description: This herbaceous perennial plant is about 3-6' tall and forms an erect, sparsely branched bush, although it is herbaceous. The stout central stem and upper side stems are smooth, light green or reddish purple, and glaucous. The compound leaves are trifoliate. They are usually greyish green or blue green, and hairless. Each leaflet is ovate or oblanceolate and pointed at both ends, with smooth margins, and about 2" long and ¾" across. The white flowers occur in erect spike-like racemes up to 2' long and are quite showy. They are typical pea flowers in overall structure, and about 1" long. There is no floral scent. The blooming period occurs from late spring to mid-summer and lasts about 1-1½ months. The flowers are replaced by large oblong seedpods, which are also rather showy. They are about 2" long and initially green, but later turn black. There is a stout deep taproot, and rhizomes that may form vegetative offsets. Once established, White Wild Indigo grows very quickly during the spring – it often towers above the surrounding plants by blooming time. Cultivation: The preference is full sun and moist to slightly dry soil. The soil can contain significant amounts of loam, clay, gravelly material, or sand. This plant is not fussy about growing conditions, and is easy to grow. However, it dislikes alkaline soil and may fail to bloom in shady conditions. Like other wild indigos, this plant may take several years to reach blooming size, but it is long-lived. The roots increase nitrogen levels in the soil. Range & Habitat: The native White Wild Indigo is widely distributed and occurs in almost every county of Illinois, but it is usually uncommon (see Distribution Map). In a few areas that are scattered around the state, this plant is locally common. Some local populations may be escaped cultivated plants, or the result of restoration efforts. Habitats include moist to dry black soil prairies, sand prairies, thickets, edges of marshes and sandy marshes, borders of lakes, limestone glades, and dry clay hills. White Wild Indigo is typically found in less disturbed habitats, partly because of limited seed dispersion. Occasional wildfires are readily tolerated. Faunal Associations: Worker bumblebees pollinate the flowers. The caterpillars of some skippers and butterflies occasionally feed on the foliage, including Erynnis baptisiae (Wild Indigo Duskywing), Achelerus lyciades (Hoary Edge), Colias cesonia (Southern Dogface), and Colias eurythema (Orange Sulfur). The caterpillars of the moth Dasylophus anguina (Black-spotted Prominent) can also be found on the foliage. Another insect, Apion rostrum (Wild Indigo Weevil), feeds on this plant and other Baptisia spp. The adult weevils eat both the leaves and flowers, while their grubs stay in the pods and eat the seeds. Because White Wild Indigo is poisonous, it is not much bothered by mammalian herbivores. If cattle, horses, or other kinds of livestock consume sufficient quantities of this plant, they can be seriously poisoned. [图片]Photographic Location: The photographs of the racemes and leaf close-up were taken at Meadowbrook Park in Urbana, Illinois. Comments: Large specimens of this wildflower are very striking while they are in bloom. White Wild Indigo is considerably taller than the related Baptisia bracteata (Cream Wild Indigo), which has spreading racemes of flowers that bloom earlier in the year. Other species of this genus in Illinois have yellow or blue-violet flowers. Another scientific name of White Wild Indigo is Baptisia leucantha.

[图片]平安树的来历却有一段美丽动人的传说：相传很久以前，有一条天龙受伤后落到今九台市莽卡满族乡境内不能行动，由于太阳晒和干旱少雨，天龙奄奄一息。当地群众闻讯后自发前来给这条龙搭了凉棚，防止太阳晒，并每天轮流给龙浇水，等到七七四“十九天后，这条龙伤愈后，腾云驾雾而起，它为了感谢这些好心的百姓救命之恩，保佑他们幸福平安，把自己的一枚龙珠投掷到今九台市胡家青松岭上，不久这枚龙珠变成一棵榆树，该树形态长得龙盘虎距，三伏天会流泪，那是天龙的感恩泪，谁喝了感恩泪，谁就心想事成，冬天该树青翠，那是天龙祝福，谁能看到谁就万事如意。 [图片]平安树能否放在卧室里一般来说植株比较小的平安树是可以放在卧室里的。这种树自身会散发出一种植物特有的清香，可能够有效去除卧室里的一些异味，对空气有着很好的净化效果。而且该树的生命力比较旺盛，光合作用能力较强，可以提高室内氧气的含量，有利于人们的身体健康。平安树摆放的位置如果想把平安树摆放在卧室里，需要注意一下摆放的位置。要注意不能将植物放在床头附近的位置，尤其是不能放在婴儿孩童的床边，这是因为植物虽然在白天会释放氧气，但是夜间没有阳光的时候是会消耗氧气的，中大型的绿植放在床头容易跟人体争夺氧气，影响人们的睡眠质量和身体健康。平安树比较喜欢阳光，如果放在向阳的地方会生长得尤其翠绿可人，同时该绿植也是比较能耐阴凉，所以选择放置位置的时候可以挑选向阳、透风的角落，这样能够促进平安树的光合作用，有利于枝叶的生长，减少树叶枯黄和徒长的现象。注意事项平安树虽然喜光，但是也不能强光照射，所以最好不要长时间放在太阳直射的地方，也不能长期至于阴暗无光的地方，会造成植株枯黄落叶、生长不良。如果是体型比较大、树叶较多的平安树，就需要根据房间面积的大小来慎重考虑要不要将其放在卧室里。因为大型植株的呼吸作用是比较强的，晚间对氧气的消耗量就会很大。如果卧室的面积比较大，放一株绿植也不会对人有太大的影响，可是如果卧室的面积比较小，还是尽量不要在房间内摆放绿植比较好。

[图片]铜钱草产中国湖南、四川、云南。生长在河沟边及阴湿的路旁草地；海拔1060-2900米。模式标本采自云南蒙自。全草入药，镇痛、清热、利湿，治腹痛、小便不利、湿疹等。多年生匍匐草本，直立部分高8-37厘米，除托叶、苞片、花柄无毛外，余均被疏或密而反曲的柔毛，毛白色或紫色，有时在叶背具紫色疣基的毛，茎节着土后易生须根。叶片薄，圆肾形，表面深绿色，背面淡绿色，掌状5-7浅裂；裂片阔卵形或近三角形，边缘有不规则的锐锯齿或钝齿，基部心形；叶柄长4-23厘米；托叶膜质，卵圆形或阔卵形。伞形花序单生于节上，腋生或与叶对生，花序梗通常长过叶柄；小伞形花序有花25-50，花柄长2-7毫米；小总苞片膜质，卵状披针形。花在蕾期草绿色，开放后白色；花瓣膜质，顶端短尖，有淡黄色至紫褐色的腺点。果实近圆形，基部心形或截形，两侧扁压，黄色或紫红色。花果期5-11月。 [图片]铜钱草可以放在卧室里面吗其实铜钱草放在卧室里面倒是没什么。从人体的角度出发，铜钱草并不会对人的身体产生什么不良的影响，没什么可令人担忧的，所以养殖在卧室是可以的。但是从实际的角度出发，铜钱草不能随随便便的就在卧室养护。铜钱草为什么不能随便养这个问题其实主要就是因为铜钱草的生长习性。铜钱草喜欢通风良好并且有明亮的光线的环境，但是卧室一般是不会满足这样的条件的。卧室的环境相对来说比较差，光照不好，通风也很差，养殖的时候，除非是大家经常的铜钱草拿出去晒晒太阳、通通风，否则它是很难长好的。如果说室内能够保证通风良好，并且至少有明亮的散射光线，养殖在晚上还是没什么问题的，只是铜钱草在生长的时候，叶子会长得比较小，没有室外养殖的铜钱草的叶子长得大。如果要在卧室里面养殖铜钱草，那还需要注意的是开花的时候将花及时的剪掉。反正铜钱草的花朵幼没什么观赏性，留在植株上面还会有花粉，对人体容易产生不良的影响。

[图片]夜来香：柔弱藤状灌木；小枝被柔毛，黄绿色，老枝灰褐色，渐无毛，略具有皮孔。叶膜质，卵状长圆形至宽卵形，叶脉上被微毛。伞形状聚伞花序腋生，着花多达30朵；花芳香，夜间更盛；花冠黄绿色，高脚碟状，花冠筒圆筒形，喉部被长柔毛，裂片长圆形，具缘毛，干时不折皱，向右覆盖；副花冠5片，膜质，着生于合蕊冠上，花柱短柱状，柱头头状，基部五棱。蓇葖披针形，外果皮厚，无毛；种子宽卵形，顶端具白色绢质种毛。花期5-8月，极少结果。 [图片]夜来香有毒吗夜来香有着浓浓的花香，虽然味道比较好闻，但是有些强烈，很多人就担心，这夜来香浓烈的香气是不是有毒。其实，夜来香的香气并不是有毒的，只不过是有些太浓烈了，长时间接触这些气味会使人感觉不舒服。不过，夜来香的香气还是有很多的作用的，尤其是在夏季的时候，因为蚊子是很讨厌这种气味的，所以夜来香可以驱蚊。夜来香可以放在卧室养殖吗其实，夜来香在养殖的时候，最好不要放在卧室里面。夜来香的香气十分浓郁，对于喜爱花香的人来说很好，但是却是不能长时间去闻。夜来香的香气会使人不舒服，刺激人们的嗅觉，并且会使患有高血压和心脏病的人感到头晕目眩，郁闷，并引起胸闷和呼吸困难等。此外长时间将夜来香摆放在室内的话，容易使人失眠。夜来香其实还是耗氧量比较大的植物，在白天的时候，进行光合作用的时候会消耗大量的氧气，对室内的空气会产生不良的影响。在晚上的时候，夜来香会停止光合作用，并释放出大量的废气，对人的健康会产生不良的影响。此外，夜来香在夜间香气会更加的浓郁，并释放刺激性的微粒。

Small Clementine oranges (Citrus reticulata "Clementine") don't have seeds. Their thin peel is simple to remove, making them a welcome treat as they ripen in winter. Like most citrus varieties, Clementine only grows in U.S. Department of Agriculture plant hardiness zones 8 through 11, but you can enjoy them in any climate by growing the trees indoors. Look for trees grafted onto dwarf or semi-dwarf root stocks -- often labeled as patio or container citrus by nurseries. "Clementine" grafted to dwarf root stock grows slowly and rarely reaches heights above 5 or 6 feet. [图片]Plant Clementine in a 20- to 24-inch-diameter container at least as deep as it is wide. Select a container with bottom drainage, and place it on a wheeled cart so it's simpler to move the heavy plant. Use a well-draining potting soil rich in organic matter, and plant the tree so that the graft union, or raised knot on the lower trunk, is just above the soil surface in the pot. Set the tree near a window that receives full, all-day sunlight. "Clementine" leaves yellow and the tree fails to fruit without sufficient sun. Set the container outside during frost-free summers to increase light exposure, and bring it indoors for winter. Alternatively, hang a full-spectrum fluorescent grow light 2 feet above the tree and leave it on all day to ensure the indoor plant receives sufficient light. Feel the soil in the pot daily, and water when the top 1 inch begins to feel dry. Pour water onto the soil with a watering can just until the excess begins to drain from the bottom of the pot. Empty the excess water from the drip tray beneath the pot after watering, because standing water can lead to waterlogged soil and root rot problems. Fertilize indoor potted Clementines year-round with a fertilizer formulated for citrus, such as a 13-7-13 blend. These trees don't enter a true dormant stage, so they require ongoing fertilization. Sprinkle 1 1/2 cups on top of the soil, a few inches from the trunk, for trees under 3 feet tall, or up to 3 cups for trees up to 5 feet tall. Water immediately after application so the fertilizer soaks into the soil. Reapply the fertilizer every two to three months. Trim off any suckers that grow along the trunk below the graft union. Cut these off flush to the trunk, using a shears sterilized in a 10 percent bleach solution. [图片]Cut off broken or dead branches any time, removing them back the to trunk or the nearest healthy wood. You can trim off small, unsightly branches from along the trunk to give the Clementine a more balanced appearance. Pinch back the growing tips of the branches by 1 inch when new growth appears in the spring to encourage full, balanced growth. Indoor citrus trees tolerate pruning at any time for shape or size control. Monitor the tree for common indoor pests, including aphids and mites. Take the tree outside or set it in a bathtub, and then spray the leaves with a sharp spray of water to dislodge and wash away these pests. If you take your Clementine outdoors in the summer, fully rinse the foliage before bringing the tree back indoors for winter.
