[图片]洋桔梗原产于美国科罗拉多州、内布拉斯加州、得克萨斯州和新墨西哥一带。从20世纪70年代开始，洋桔梗作为切花开始在日本和朝鲜等地流行起来。 [图片]是否适合卧室养？ 洋桔梗的毒性 洋桔梗属于龙胆科，龙胆科的植物或多或少都带毒，比如同属龙胆科的桔梗的根便有毒，它里面含有桔梗皂甙，是一种溶血作用很强的成分。但是很幸运的是洋桔梗是不带毒的，而且全身无毒，不管是误食还是长时间与他接触都不会产生任何问题，可以说是非常亲近人的一种植物了。因此，放在室内养是没有问题的！ 卧室养殖的注意事项 洋桔梗生长的温度条件 最适宜洋桔梗生长的温度为15～28℃，因此洋桔梗不耐低温，如果环境温度低于5摄氏度就不会开花。晚上不能太冷到12摄氏度以下，当然也不能太高，一旦高于30℃，就会导致花期提前结束。因此，如果冬季把洋桔梗放到室内生存，在温度上是十分适宜的，尤其是北方的花友朋友们千万不能随手把娇贵的花朵仍在寒冷的阳台上。 洋桔梗生长的光照条件 另外冬季比较寒冷，光照强度也比较弱，对于洋桔梗这种喜欢晒太阳的植物来说，接收不到充足的阳光就无法开出迷人的花朵。因此不能放在室内的背阴处，卧室内的阳台比较适宜。 洋桔梗生长的湿度条件 洋桔梗喜湿但畏水涝，冬季不用浇水太多，在卧室里没有风吹日晒，如果房间里有加湿器那就事半功倍了。 另外最后还有一点就是洋桔梗的观赏价值。洋桔梗作为一种常见的切花材料，花型美观大方，是非常适宜放在花瓶里作为插花的。搭配优雅的木制家居用品和简洁大方的瓶器，代表着爱与希望的洋桔梗会给生活增添一抹明媚的亮色。

Description: This shrubby perennial is up to 3¼' tall. It tillers at the base, sending up multiple stems that are erect to ascending. These stems are light green to light yellow, terete, and pubescent or hairy, becoming woody with age in the absence of fire or browsing from animals. The leaves are alternate or opposite; they occur along the entire length of each stem. The leaves are up to 3" long and 2" across; they are ovate in shape and their margins are smooth to finely serrated and slightly ciliate. The upper leaf surface is pale-medium to dark green, and smooth to somewhat rough from minute stiff hairs. The lower leaf surface is pale green and pubescent or hairy; hairs are typically more abundant along the lower sides of the veins. The central vein and two primary lateral veins are palmate, while the remaining veins are pinnate; the upper leaf surface is often wrinkled along these veins. The petioles are short, light green to light yellow, and pubescent or hairy. The upper stems terminate in panicles of flowers; axillary panicles of flowers also develop from the axils of upper leaves. The peduncles (basal stalks) of these panicles are 2-8" long, light green to light yellow, terete, relatively stout, and pubescent or hairy. Individual panicles are 2-5" long and 2-3" across; their lateral branches are up to 1½" long and widely spreading to ascending. Both the rachis and lateral branches are light green, terete, relatively stout, and finely hairy. Along the rachis and lateral branches of each panicle are clusters of flowers on slender white pedicels. These pedicels are ¾–1" long. Each flower is up to ¼" across, consisting of 5 white sepals, 5 white petals, 5 stamens, and a pistil. The sepals are triangular-ovate and folded inward, while the petals are widely spreading. The petals have long narrow bases and widened tips; the lateral edges of these tips are folded upward. The blooming period occurs during early to mid-summer, lasting about 3-4 weeks. There is a pleasant floral fragrance. Afterwards, the flowers are replaced by 3-lobed seed capsules up to ¼" across. At maturity, these capsules become dark brown or black, and they split open to mechanically eject their seeds up to several feet. Each capsule contains 3 seeds that are 2-3 mm. in length, brown to dark brown, glossy, and ovoid in shape. The root system consists of a stout taproot. [图片]Cultivation: The preference is full or partial sun and average to slightly dry conditions. The soil can contain loam, rocky material, or sand. This plant adds some nitrogen to the soil. Germination from seed can be slow and difficult – exposing them to hot water may be helpful. Transplants are easier to manage and faster to develop. Drought resistance is very good – under severe conditions, the leaves will become discolored and shrivel, but quickly revive when rainfall returns. Foliar disease is rarely a significant problem. Range & Habitat: The native New Jersey Tea occurs throughout Illinois, except for a few counties in the southern part of the state (see Distribution Map). It is occasional to locally common in high quality habitats, but uncommon elsewhere. Habitats include mesic to dry black soil prairies, gravel prairies, sand prairies, hill prairies, sandy savannas, rocky upland forests, limestone glades, and barrens with scrubby vegetation. Occasional fire is a beneficial management tool in promoting the development and spread of this plant. [图片]Faunal Associations: The nectar and pollen of the flowers attract a variety of insects, especially bees, wasps, flies, and beetles. These floral visitors include Halictid bees (Agapostemon spp., Halictus spp., Lasioglossum spp.), Andrenid bees (Andrena spp.), plasterer bees (Colletes spp.), Sphecid wasps (Oxybelus spp., Cerceris spp., Tachysphex spp.), Vespid wasps (Polistes spp., Stenodynerus spp.), spider wasps (Anoplius spp.), Syrphid flies, thick-headed flies (Conopidae), Tachinid flies, flesh flies (Sarcophagidae), bottle flies (Lucilia spp.), Muscid flies, and miscellaneous beetles (Robertson, 1929). Hairstreak butterflies (Satyrium spp.) also visit the flowers. Other insects feed destructively on the foliage, seeds, and other parts of New Jersey Tea. These species include stem-boring larvae of a long-horned beetle (Calliomoxys sanguinicollis), leaf beetles (Babia quadriguttata, Pachybrachis trinotatus), seed-eating broad-headed bugs (Alydus spp.), and the Angulate Tingid (Gargaphia angulata); see Yanega (1996), Clark et al. (2004), Schaeffer (1980), and Cranshaw (2004). In addition, the larvae of several moths feed on New Jersey Tea, including the Broad-lined Erastria (Erastria coloraria), Sulfur Moth (Hesperymia sulphuraria), and Red-fronted Emerald (Nemoria rubrifrontaria); the caterpillars of a butterfly, the Spring/Summer Azure (Celastrina argiolus), and caterpillars of a skipper, the Mottled Duskywing (Erynnis martialis), also feed on this shrub (Covell, 1984/2005; Bouseman & Sternburg, 2001; and Bouseman et al., 2006). [图片]The foliage and stems are readily consumed by various mammalian herbivores, including elk (native in Illinois at one time), deer, rabbits, and livestock (Martin et al., 1951/1961). Some upland gamebirds, like the Wild Turkey and Bobwhite Quail, also use New Jersey Tea as a food source (Van Dersal, 1939). This can make the establishment of this plant difficult where there is an overpopulation of such animals. Photographic Location: The photographs were taken at Loda Cemetery Prairie in Iroquois County, Illinois. Comments: This little shrub has a lot going for it from both horticultural and ecological perspectives. It was used by colonists during the Revolutionary War as a substitute for tea (hence the common name), even though the leaves contain no caffeine. Early pioneers discovered that the stout roots of New Jersey Tea (Ceanothus americanus) were a formidable barrier to the plow. Chemical compounds from this plant have been found to affect the speed of blood coagulation (Lynch et al., 1958), and they have been found to have antimicrobial properties on oral pathogens (Li et al., 1997). The only other species in this genus that occurs in Illinois, Redroot (Ceanothus ovatus), differs from New Jersey Tea by having more narrowly shaped leaves and shorter panicles of flowers.

Description: This perennial plant is about ½–1½' and unbranched, except for some upper side stems near the inflorescence. Often, several stems will emerge from the same rootstock; they remain reasonably erect. The basal leaves have long petioles, and are about 1" across. They are usually cordate or orbicular and their margins are bluntly dentate. The basal leaves often wither away by flowering time. Along the slender central stem are alternate leaves. These leaves are linear and about ½–2" long. They usually angle upward from the stem, and then curve outward. Usually the foliage and stems are without hairs, although sometimes they are slightly pubescent. [图片]The central stem (and some of the side stems) terminates in either a solitary flower, or a short raceme of 2-3 flowers. These flowers are violet and bell-shaped. A typical flower is about ¾" long, and tends to hang toward from a slender pedicel. The corolla has 5 short lobes that curve outward. The interior of a flower is white or pale violet near the base, while a long violet style projects slightly beyond the outer rim of the corolla. This style terminates into a tripartite white stigma. The green calyx divides into 5 slender segments that are slightly recurved. The blooming period occurs from early to late summer, and lasts about 2-3 months. There is no noticeable floral scent. The flowers are replaced by ovoid capsules that contain numerous tiny seeds. These seeds are easily dispersed by gusts of wind. The root system consists of a taproot. Cultivation: This little plant prefers full sunlight and moist to dry conditions. It typically grows in shallow rocky soil, but will flourish in ordinary garden soil if taller, more aggressive plants are kept away. Harebell is surprisingly easy to grow, notwithstanding its delicate appearance. It tolerates alkaline soil. Range & Habitat: The native Harebell is an uncommon plant that occurs primarily in northern Illinois (see Distribution Map). It is more common in areas to the north and east of Illinois. Habitats include sandy Black Oak savannas, hill prairies, crevices of sandstone, limestone, or dolomite cliffs, and shallow rocky soil along streams. It also occurs along roadsides in neighboring states. Generally, Harebell is found in high quality habitats where there are rocky slopes. It also cultivated in gardens. Faunal Associations: Various bees often visit the flowers, where they seek nectar. While the foliage is potentially edible to mammalian herbivores, only the basal leaves are sufficiently large to attract much attention from them. The seeds are too small to be of any interest to birds. [图片]Photographic Location: The photographs of the flowers were taken at the webmaster's wildflower garden in Urbana, Illinois, while the photograph of the basal leaves was taken at the Japan House of the University of Illinois in the same city. Comments: This is a charming little plant. Harebell is distributed in both the Old World and New World, and may be variable across its large range. The native Campanula aparinoides (Marsh Bellflower) has smaller flowers and is found in wetland areas. Sometimes non-native bellflowers escape into the wild, such as Campanula rapunculoides (Creeping Bellflower), but they have broader foliage and larger flowers.

Description: This perennial wildflower consists of a low rosette of basal leaves up to 1½' across and a flowering stalk about 1½–2' tall. The floppy basal leaves are 6-12" long and 1/3" (8 mm.) across; they are medium to dark green, linear in shape, parallel-veined, glabrous, and smooth along their margins. Along the underside of each basal leaf, there is a prominent mid-rib. The erect central stalk is slender, light to medium green, and glabrous; it terminates in a spike-like raceme of flowers that is several inches in length. Underneath the floral spike, there are usually 1-3 bracts along the stalk. These bracts are green, linear to linear-lanceolate in shape, and up to ¾" long. Each flower is ¾–1" across, consisting of 6 tepals, 6 stamens with bright yellow anthers, and a green central ovary with a slender style. The tepals are light blue-violet to nearly white; they are oblong in shape and spread widely from the center of the flower. Each tepal (petal or petal-like sepal) has 1-3 poorly defined veins along its length. [图片]At the base of each flower, there is a single linear bract up to ¾" long that is early-deciduous. The slender pedicel of each flower is about the same length as the bract. The flowers begin to bloom from the bottom of the raceme and continue to bloom upward toward the apex; each flower lasts only 2-3 days. The blooming period occurs from mid- to late spring and lasts about 2-3 weeks. Each fertilized flower is replaced by a 3-celled seed capsule that is about 1/3" in length and nearly as much across. Each seed capsule contains many small seeds that are black and shiny. The basal leaves turn yellow and wither away by mid-summer. The root system consists of a bulb with fibrous roots. This wildflower reproduces by reseeding itself. Cultivation: The preference is full sun to light shade, moist conditions, and rich loamy soil. Wild Hyacinth is slow to develop, but fairly long-lived. Vegetative growth and development occurs during the cool weather of spring, when adequate moisture is essential. Range & Habitat: Wild Hyacinth is found occasionally throughout Illinois (see Distribution Map), where it is native. Habitats include moist black soil prairies, moist savannas, moist open woodlands (particularly along the banks of streams), rocky wooded slopes, and limestone glades. This species is typically found in high quality habitats, whether prairies or woodlands. Faunal Associations: The flowers attract their fair share of insects, including many bees and flies, and occasional butterflies and wasps. Most of these insects seek nectar from the flowers, although some short-tongued bees also collect pollen. Bee visitors include honeybees, bumblebees, Cuckoo bees (Nomada spp.), and Halictid bees (Halictus spp., Lasioglossum spp., etc.). Other floral-faunal relationships are poorly understood. White-Tailed Deer occasionally chomp off the tops of the basal leaves. Both the foliage and bulbs are not known to be toxic to mammalian herbivores. Photographic Location: Along a woodland stream in Douglas or Coles County in east-central Illinois. [图片]Comments: Wild Hyacinth has attractive flowers that are conspicuous during the spring. It is usually found in woodland habitats, but also occurs in prairies. Wild Hyacinth differs from the less common Camassia angusta (Prairie Hyacinth) in several ways, among them: 1) It has slightly larger flowers than the latter, 2) its flowers are usually a slightly lighter shade of blue-violet, 3) its seed capsules are about as broad as long, while Prairie Hyacinth has seed capsules that are slightly longer than broad, 4) the bracts of its flowering stalk are less persistent than those of Prairie Hyacinth, and 5) it blooms earlier in the spring.

Description: This perennial plant consists of a rosette of basal leaves up to 1½' across and one or more flowering stalks up to 2½' tall. The strap-shaped basal leaves are up to 14" long and 1" across; they are linear, smooth along the margins, and glabrous. Their veins are parallel. These basal leaves are rather floppy and they often arch downward or sprawl across the ground in the absence of support from other vegetation. The basal leaves wither away by mid-summer. The flowering stalks are erect, slender, hairless, and leafless. Each stalk terminates in a raceme of about 20-80 flowers. Each flower consists of 6 lavender to pale blue-violet tepals, 6 stamens with golden yellow anthers, and a light green pistil with a short slender style. Each flower spans about ¾" across when it is fully open. The pedicels of the flowers are slender, green, and deciduous, unless the flower is successfully cross-pollinated. Underneath each flower, there is often a persistent bract about ¾" long that is thread-like in appearance. After the flowers begin blooming on the raceme, there can be 3-20 (or more) of these bracts underneath. Several flowers bloom in a ring at the same time, which forms at the bottom of the raceme and moves upward. The blooming period occurs from late spring to early summer and can last up to 1 month for a colony of plants. The flowers that are successfully cross-pollinated form seed capsules that are ovoid-oblongoid in shape. Each capsule contains several seeds. The root system consists of a bulb with secondary fibrous roots at the bottom. This plant reproduces by forming offsets from the bulbs and by reseeding itself. Cultivation: The preference is full or partial sun, moist to mesic conditions, and a fertile loamy soil. This plant is rarely bothered by disease and insect pests. It is somewhat slow to develop, especially from seeds. Range & Habitat: In Illinois, Prairie Hyacinth is a rare plant that has been observed in Macon and Peoria counties only (see Distribution Map). At the present time, only one population of plants is known to exist within the state at a railroad prairie. Apparently, the other population has been extirpated. In neighboring states, Prairie Hyacinth has been observed in prairies and thinly-wooded areas. This native species is state-listed as 'endangered' in Illinois. Faunal Associations: The flowers attract both long-tongued and short-tongued bees, which suck nectar or collect pollen. Other visitors of the flowers include various flies, butterflies, skippers, wasps, and beetles, which suck nectar or feed on pollen. Aside from these flower-visiting insects, little information is available about floral-faunal relations for this wildflower. [图片]Photographic Location: The webmaster's wildflower garden in Urbana, Illinois. Comments: This little-known species is sometimes confused with Camassia scilloides (Wild Hyacinth), which is more common within the state. Both species are attractive wildflowers with similar habitat preferences. Their appearance is quite similar, which can make them difficult to tell apart. Prairie Hyacinth begins to flower about a month later than Wild Hyacinth and there is little overlap in their blooming periods; this is one good reason why they should be considered separate species. The flowering stalk of Prairie Hyacinth has 3-20 (or more) persistent bracts underneath the blooming flowers, while Wild Hyacinth has 0-2 deciduous bracts underneath the flowers of its stalks. The seed capsules of Prairie Hyacinth are longer than they are wide, while the seed capsules of Wild Hyacinth are about as long as they are wide. The flowers of Prairie Hyacinth tend to have shorter styles, shorter stamens, and tepals that are a little shorter and more deeply colored, but these distinctions are less reliable, or they require the careful use of a ruler or measuring tape in the field.

Description: This perennial plant is ¾-1½' tall and unbranched. It is usually erect, but sometimes sprawls across the ground. The central stem is light green and hairy; it rarely twines about the stems of adjacent plants, fences, or other objects. Alternate leaves about 1½-3" long and about one-half as much across occur along the central stem. They are yellowish green to dull green, oblong-cordate in shape, smooth along their margins, and slightly to moderately hairy. The leaf bases are usually cordate (less often truncate or rounded), while their tips are blunt or pointed. Each leaf usually has a short petiole about ½" long or less; sometimes the upper leaves are sessile. Occasionally, individual flowers develop from the axils of the leaves; there are 1-4 flowers per plant. Each flower is about 2-3" long and 2" across, consisting of a white (rarely pink) funnelform corolla with 5 shallow lobes, 5 light green sepals, several stamens, and a pistil with 2 white stigmata. At the base of the flower, 2 sepal-like bracts surround the sepals; these bracts are light green and ovate. The pedicel is 1" long or less. The blooming period occurs from late spring to mid-summer and lasts about 1-2 months. On any given day, only 0-1 flowers are in bloom per plant. Each large flower opens up during the early morning and closes at around noon; it lasts only a single day. Fertilized flowers are replaced by globoid seed capsules; each capsule is 2-celled and about 1/3" across. Each cell of the capsule contains a single large seed. The root system is rhizomatous, occasionally forming vegetative offsets. Cultivation: The preference is full sun, dry conditions, and soil containing sand, rocky material, or clay. Range & Habitat: The native Erect Bindweed is found primarily in central and northern Illinois, where it is uncommon (see Distribution Map). Populations of this species have declined across the state. Habitats consist of upland sand prairies, gravel prairies, hill prairies, open rocky woodlands, limestone glades, and roadside embankments. Erect Bindweed tends to increase in response to occasional wildfires as this reduces woody vegetation and excess debris. This is an indicator plant of high quality prairies. [图片]Faunal Associations: Little is known about floral-faunal relationships for Erect Bindweed, although there is some information available about its more weedy relatives, e.g. Calystegia sepium (Hedge Bindweed). The flowers are cross-pollinated primarily by miscellaneous long-tongued bees. The caterpillars of Agrius cingulatus (Pink-Spotted Hawk Moth) require bindweed as a food source; the caterpillars of Emmelina monodactyla (Common Plume Moth) and Bedellia somnulentella (Morning Glory Leafminer) also feed on the foliage of species in the Bindweed family. Several beetles feed on the foliage and other parts of these same species: Typophorus nigritus (Sweet Potato Leaf Beetle), Strongylocassis atripes and other tortoise beetles, Chaetocnema confinis (Sweet Potato Flea Beetle), the stem-boring beetle Phaea monostigma, and the seed weevil Megacerus discoidus. One insect, Charidotella sexpunctata (Golden Tortoise Beetle), has been found on the foliage of Erect Bindweed specifically. There are also records of upland gamebirds eating the seeds of bindweed species: the Bobwhite, Ring-Necked Pheasant, and Prairie Chicken. [图片]Photographic Location: The Coneflower Hill Prairie near Lake Shelbyville in Moultrie County, Illinois. The flowers are mostly closed because the photograph was taken after the blooming period during the morning. Comments: Unlike Erect Bindweed, most species in the Bindweed family are long twining vines that are adapted to thickets, overgrown meadows, and similar habitats. Most of these species are weedy annuals, although Ipomoea pandurata (Wild Sweet Potato) is a perennial with a tuberous swollen root. Species that are twining vines produce large showy flowers in abundance. While the flowers of Erect Bindweed are also large and showy, they are sparingly produced. All of these species have short-lived flowers that remain open during the morning of a single day. Other common names of Calystegia spithamaea are Dwarf Bindweed, Low Bindweed, and Low False Bindweed. An older scientific name of this species is Convolvulus spithamaeus.

[图片]多肉冬天每天应该晒多久太阳 并不是所有的多肉都适合晒太阳，也不是所有的多肉晒太阳的时间都一致。寿类及玉露，不管是哪个季节都不适合晒太阳，只可以给它们一些散光即可，如果非要晒太阳，也只能是临近太阳下山时的1至2个小时晒；有些多肉是整个冬季都在照晒，而且有些多肉则要避开午间的阳光，虽然冬季午间阳光并不算太毒辣。所以在给肉肉制定晒太阳时长的计划时，一定要先了解肉肉的生活特点。 [图片]冬天晒太阳注意事项 若是长期不晒太阳的肉肉，也不要长时间让它晒太阳，要一点一点增加晒太阳的时间，但要忌暴晒。 冬季若能让喜光照的肉肉们享受到阳光的沐浴，对于肉肉来说也是一件舒服的事。但是你若管理不当，肉肉也是会让你哭的，比如浇水。在肉肉享受阳光的时候，一定不要让植物表面有水渍，其叶心更不能有积水。 刚栽种的多肉就不要放在阳光下了，此时它们的根部还在缓根时期，此时无法吸收水分，而若在阳光下摆放，会让植物进入缺水状态的。大约4天至7天后在晒太阳。 [图片]

[图片]整枝修剪 对夏鹃盆景进行整枝修剪可以调整植株的生长状况，使其发育得更加旺盛，枝叶形态更加优美。 如果想对夏鹃整体修改型态、大幅修剪，要在春天植株生长旺盛的时候进行，如果长势较弱还必须修剪，则应先追肥培育，在夏鹃恢复精气之后再进行。另外，需要同时进行翻盆换土、去除老根，整体改善夏鹃的生长环境。 [图片]花前修剪 在花期之前，要适当修剪枝叶，去掉徒长的长枝、乱枝，这样在花期到来之后整个盆景就会有一个整齐自然的树冠。 花后修剪 花期之后要对枝干进行整修，如果任由新枝生长，就会破坏原有的平衡，新枝多的部位也会变粗，显得很不和谐。此时修剪要保留一两根长势方向都很好的新枝，侧面的枝条则去除竖向和逆生的枝条，保留横向生长的新枝。当然，如果想要主干加粗，则新枝可暂时不修剪。需要注意的是，花期之后的修剪要在六月中旬完成。 日常修剪 平常的盆景整理只要剪掉病弱的、杂乱的和徒长的枝桠即可，这种修整可以增强枝干和根系的生长平衡，还可以增加透光和通风性，利于夏鹃的整体发育。 吊扎 同其他盆景一样，夏鹃盆景也讲究架构、层次和疏密，一般而言，夏鹃盆景要先进行修剪然后再通过吊扎等技术做出完善的造型。需要注意的是，该花枝干比较脆弱，在吊扎前要先用水将枝条稍微软化一下，然后用铁丝对预留的枝条进行吊扎造型。 [图片]注意事项 无论怎样修剪，夏鹃的体型总会不断增长，因此每过三年都要进行一次大规模的修整，剪掉多余的花枝，压缩盆景的体积。同时，还要换土翻盆进行保养，这样才能使夏鹃盆景一直处于良好的生长状态，保持着妩媚优雅的造型。
