姬星美人是非常袖珍的多肉植物品种，"姬"正代表她"迷你"的意思，翡翠般的深绿色细小叶片很适合用于多肉拼盘的点缀，十分适合摆放窗台、阳台和客厅。姬星美人正常的颜色应该是蓝绿色，夏天阳光强的情况下，姬星美人会变的矮小，匍匐在地上，颜色呈现非常迷人的所谓的蓝粉色，非常的可爱。
姬星美人叶子变黄原因：正常现象 若姬星美人靠近地表的叶片开始发黄，逐渐萎蔫，是正常现象，因为植株在生长过程中，不会伴随着养分的消耗。多肉植物会消耗底部的叶片来获取养分，而且底部都是一些老叶，萎蔫之后不会影响植株的生长，反而会加快植株自身的代谢，促进更新。 姬星美人叶子变黄原因：浇水过多 乍一看到图片，许多肉友会说，哇塞，很漂亮啊，这是叶片发黄的前兆，主要原因就是浇水过多，每个枝条顶端的较大的叶片会变成透明状，颜色较浅。浇水过多，造成根部腐烂，枝叶水分吸收受阻，造成生理性缺水，从而造成叶子发黄。 在养护过程中尽可能的少浇水，不干不浇。若浇水过多，就多晒晒太阳，松松土，若盆土还是长时间湿润，那就只能换盆了！ 姬星美人叶子变黄原因：光照不足 姬星美人在阳光充足的环境下会变成蓝色，非常漂亮，但正常情况下会保持绿色，只有少数情况，缺少光照会颜色暗淡。所以你要确定是否是因为缺少光照导致姬星美人叶子发黄。 如果是光照原因导致叶子发黄，那就容易很多，补充光照就好，放在阳光下多晒晒。 姬星美人叶子变黄原因：病虫害 姬星美人叶子发黄可能是病虫害在做怪，仔细观察叶片上有没有出现斑点，或者白色的小虫子，一旦发现及时清理干净。 姬星美人的植株很小，叶片较厚，成簇生长，发生虫害很难发现的。所以要以预防为主。在养护中每个月喷洒一下杀菌药剂。
一直喜欢姬星美人，袖珍，好养，够萌，不用操心，随便给她点阳光就能出效果，去年10月，掉在地上几个月的姬星美人居然生根活了，于是我把他们换到粗瓶子里养着，不到半年，变成胖妞了，呵呵，好吧，你想胖就胖吧~

吹雪之松锦原产纳米比亚，是一种变异带有白色锦斑的多肉植物。马齿苋科、回欢草属多肉植物，别称回欢草，顶端叶片似莲花展开，叶面厚实，五彩雍华，喜阳，但忌长时间放在烈日下。株高仅5厘米，叶色倒卵形，叶腋间有白色丝状毛，开玫瑰色小花。变异品种叶上有橘红色斑块，更具观赏性。是马齿苋科中唯一被作为多肉植物介绍的一类。在养殖过程中，养护不当会出现吹雪之松锦叶片发皱、烂根现象，接下来一起看看吹雪之松锦发皱原因及怎么解决。
吹雪之松锦发皱分析 吹雪之松锦皱了大部分是烂根了，水多了就会烂根。换个底部能透水的花盆。把多肉植物拔出来，检查一下根系的情况，把腐烂的根去掉，把多肉植物晾几天，然后再湿土干栽，过一段时间新的根生出来就好了。土壤不干不浇水，浇水一次要浇透(看到水从花盆底部渗出来)，如果花盆下面用了托盘，不要让渗出的水积在托盘里。放在明亮透风的地方。夏天日照时不要让阳光直射，以免灼伤叶片。
吹雪之松锦养殖事项 1、吹雪之松锦养殖：盆土配制 吹雪之松锦锦为浅根性肉质植物，盆栽土须用腐叶土和粗沙的混合土，盆栽时，盆底要多加瓦片，以便有良好的排水性。 2、吹雪之松锦养殖：光照充足 吹雪之松锦锦喜阳，能在全日照环境下生长最好，但忌长时间放在烈日下，夏季高温强光时适当遮荫。 3、吹雪之松锦养殖：浇水适量 夏季没有明显的休眠期，但要减少浇水，保持盆土干燥，不宜浇水过多否则会导致烂根的现象。 4、吹雪之松锦养殖：温度控制 平常在室内养吹雪之松锦锦，要保持温度在15~28为好，最低温5度、最高温35度是植株忍受的极限。 5、吹雪之松锦养殖：通风良好 不论是养什么植物，通风是很重要的环节，在闷热的夏天，到了夜晚要加强通风。 吹雪之松锦作为观赏植物，适宜用小盆栽种，陈设于窗台、案头、书桌、阳台等处，闲暇之时细细观赏其独特的株型、叶片，从中领悟大自然之神奇，植物之妙趣。

玉树是最好养的多肉吧？很久之前就看见过别人家随意丢都在院子里的土都干得裂缝的玉树，感觉它好坚强！我去年扦插了一枝，没怎么费工夫它就活了。生怕它干枯了，随时都把花盆里装满水，离开一周也照样昂首挺胸，虽说没开花没上色，却长势喜人，枝干比拇指还粗了。后来还切了一枝给同事，也是长得旺盛。 当然在好养的植物都有叶子发黄、发软的时候。那么是什么原因造成的呢？
玉树叶子发黄、发软原因分析 最常见的玉树叶子发软的原因是因为缺水，一般这种情况及时浇水就可以很快恢复，但是也有一些花友发现自己的玉树是莫名其妙的叶子发软，不知道该如何下手查找原因，下面我们来总结一些常见的排查玉树叶子发软的方法： 1、玉树发黄：水量大 前面我们已经说了，玉树的叶子含水量很大，所以首先检查是不是缺水了。 2、玉树发黄：光照 玉树忌暴晒，检查是不是突然把玉树从室内搬到室外了，叶子被晒蔫了，这种情况应该将玉树及时挪到阴凉的散光处养护。 3、玉树发黄：烂根 玉树还是比较容易烂根的，浇水多了，容易导致烂根，这个可以根据自己的浇水情况来排查，如果烂根，只有挖出来看看根的情况，适当处理重新栽种，如果严重，只能重新扦插了。 4、玉树发黄：通风 玉树需要通风良好的环境，有时候花友们的玉树是在比较闷的环境中，这不利于玉树的生长。 还有诸多原因，比如有换盆后叶子发软的，室内搬到室外暴晒导致叶子变软的等等，花友要结合自己的实际情况来排查。 春夏间可以给玉树换土，夏季到了，玉树移放室外养护，应先放在阴凉处，再移置强光下，放在屋檐下、阳台后口处最佳。平时浇水也不要过多过勤，见盆土表面发干时再浇。到了冬季，玉树就可安心地放在室内养护。
玉树景天科青锁龙属多肉植物有多个别名燕子掌、厚脸皮、玻璃翠、豆瓣掌等。小型灌木状肉质植物，茎圆柱形，灰绿色，肉质，多分枝，有节。叶对生，扁平肉质，椭圆形，全缘。玉树喜温暖、干燥和阳光充足环境。不耐寒，耐干早，怕积水，忌强光，稍耐阴。生长适温22一27℃。冬季温度不低于7℃。宜肥沃和排水良好的沙质壤上。玉树有“富贡吉祥”、“财源滚滚”等花语，盆栽茎干基部膨大，枝叶肥厚，四季碧绿，叶形奇特，株形庄重，宜于盆栽水养，装饰茶几、案头，翠绿清秀，十分诱人。非常适合家庭点缀。

子持年华烂根原因分析及解决方法 子持年华，很有诗意的一个名字。它在多肉植物中也算是比较好养活的一种，爆盆也非常容易，且爆盆后的观赏价值非常高。但在养殖过程中同样也会遇到烂根的情况，今天就来给友友们分享下烂根的原因与防治方法。
子持年华烂根原因分析 1、子持年华烂根：爱肉多动症 许多初期肉友在养肉时，急于求成，肉肉出一点问题，就会连根拔出，看看是什么问题。幼小的根茎怎么受得住这样折腾吗？就算本来生长良好，折腾几次，根的生长就会受到影响，若栽种时不注意，根部受伤，烂根在所难免。 2、子持年华烂根：冬天换盆找死 子持年华冬季会进入休眠期，肉友会认为，这个时候怎么动子持年华都没有事，就将死掉的叶子都清理干净，重新换盆，希望春天可以焕发新绿。万万没想到，反而作死。子持年华冬季是休养生息的时候，你这么折腾，怎么会好！ 3、子持年华烂根：土壤不透气 子持年华适宜生长在湿而不涝的环境中，当土壤湿度过大，透气性又差，就很容易造成烂根。
子持年华烂根处理方法 1、子持年华烂根处理：丢进土里 若子持年华根部已经完全腐烂，可以将叶片全部摘到，让其自生自灭，说不定会长出几个小子持。 2、子持年华烂根处理：子持年华叶片叶插 至于周围的走茎，没有化水的可以直接剪下，重新栽种，这部分成活的几率还是很大的。 3、管住手不要随便动 平时养护，不要随随便便就把根整个拔起，冬季也不要随便换盆。除非需要换盆，平时不要轻易将植株脱盆。 子持年华养护三要素： 土壤：子持莲华的土壤一般选用泥炭混合珍珠岩加浮石，比例1:1:1，为了不使植株和土表接触，也为了更加透气，可以铺上颗粒的干净河沙，河沙尺寸3到5毫米，沙层厚度5毫米左右。 光照：子持莲华是喜光性植物，尤其是在生长期，最好是全天日照。而在冬眠期的时候则要进行遮阳，防止过早的打破休眠期。 浇水：子持莲华浇水一般是干透才浇透，不干不浇水。炎热的夏季一般每个月4到5次水，不浇透，以维持植株的正常生长，夏季浇水太多容易腐烂。冬天温度低于5度就要逐渐断水，3度以下保持盆土干燥，尽量保持不低于零下20度。

Description: This is a herbaceous perennial plant about ½–2' tall that branches occasionally. The stems are light green to pale red, terete, slightly hairy, and shiny. Both basal and alternate leaves are produced. Basal leaves are compound or simple with long petioles; compound leaves are odd-pinnate with 3-7 leaflets. Simple leaves are orbicular, shallowly cleft, and dentate; the leaflets of compound leaves are ovate, shallowly or deeply cleft, and dentate. Alternate leaves are usually trifoliate with short petioles; their leaflets are narrowly ovate, cleft, and dentate. The upper surfaces of these leaves are medium to dark green and hairless to hairy. At the base of each leaf, there is a pair of large leafy stipules; these stipules are deeply cleft and dentate along their margins. Flowers develop from the upper stems on long branching stalks; each stalk terminates in an individual flower about ¼" across. Individual flowers also develop from the axils of the upper leaves on long unbranched stalks. These flowering stalks are slightly hairy, shiny, and terete like the stems. Each flower has 5 yellow petals, 5 light green sepals, and a dense cluster of pistils and stamens in the middle. The petals are about the same length as the sepals (less than 1/8" or 3 mm.); the sepals are ovate and hang downward from the rest of the flower. The blooming period occurs from mid- to late spring and lasts about 3 weeks; only a few flowers are in bloom at the same time. Each flower is replaced by dense cluster of bristly achenes; the receptacle of this clustered fruit is exerted from the calyx on a short stout stalk. The individual achenes are ellipsoid in shape and hairless to pubescent; the hooked bristles at their tips are persistent styles. The root system is fibrous and rhizomatous. Cultivation: The preference is dappled sunlight to light shade, moist to mesic conditions, and a rich loamy soil. Most growth and development occurs during the spring. Range & Habitat: The native Spring Avens is common in the southern half of Illinois, while in the northern half of the state it is occasional, uncommon, or absent (see Distribution Map). Habitats include rich deciduous woodlands, open woodlands, areas along woodland paths, shaped seeps, woodland borders, and fence rows with woody vegetation. Spring Avens can be found in both disturbed and undisturbed areas that receive some shade.
Faunal Associations: The flowers attract small bees primarily, including little carpenter bees, Halictid bees, cuckoo bees (Nomada spp.), and masked bees (Hylaeus spp.); these small bees suck mostly nectar, although some of the Halictid bees collect pollen for their larvae. Occasionally, Syrphid flies, Tachinid flies, and other flies also visit the flowers. The leaves of Spring Avens and other woodland Geum spp. (Avens) are grazed sparingly by White-tailed Deer. The bristly achenes can cling to the fur of mammals, feathers of birds, and clothing of humans. By this means, they are distributed into new areas. Photographic Location: A floodplain woodland in Vermilion County, Illinois. Comments: This is the first woodland Geum sp. (Avens) to bloom in Illinois. Because the yellow petals of its flowers are quite small and short-lived, Spring Avens is not very showy. In contrast, its leaves are moderately attractive and variable in shape. Other woodland species in this genus include Geum canadensis (White Avens) and Geum laciniatum (Rough Avens). These species have flowers with white or cream petals and they bloom a little latter in the year (late spring to early summer). Unlike other species in the genus, the bristly fruits of Spring Avens are exserted from their calyces on short stout stalks. The fruits of other Avens lack these stalks. Thus, Spring Avens is easily identified by this peculiar characteristic.

Description: This herbaceous perennial plant is 1-2½' tall, consisting of a loose cluster of basal leaves and flowering stems that develop directly from the creeping rootstock. On the lower portion of each flowering stem, there is a pair of opposite leaves. Both the basal leaves and the lower opposite leaves of the flowering stems have a similar appearance. They are up to 5" long and across, and palmately cleft with 5 deep lobes. Each of these lobes is wedge-shaped at the base. The leaf margins have a few secondary lobes and coarse teeth. The upper pairs of leaves on the flowering stems are like the lower leaves, except they are smaller in size and they usually have 3 primary lobes, rather than 5. The upper leaf surface is medium green with fine appressed hairs. The long petioles of these leaves are light green, terete, and coarsely hairy. The flowering stalks (peduncles) are up to 6" long and ascending to erect; like the stems with opposite leaves, they are light green to reddish brown, terete, and coarsely hairy. Each flowering stalk terminates in a floppy corymb or umbel of 2-5 flowers; sometimes only a single flower is produced. Each flower is about 1–1¼" across, consisting of 5 rounded petals, 5 green sepals, 10 stamens with pale yellow anthers, and a single pistil with 5 carpels. The petals are pale purplish pink and obovate with rounded tips; they have fine veins radiating across their surfaces that function as nectar guides. The sepals are light green, hairy, lanceolate-oblong or elliptic-oblong in shape, and cuspidate (tapering abruptly into short narrow tips); they are shorter than the petals. Both the flowering stalks (peduncles) and pedicels have non-glandular hairs. The blooming period occurs during the late spring to early summer, lasting about 1 month. The pistil of the flower elongates into a beak-like fruit about 1–1½" long. As it matures, the 5 slender carpels of this fruit curl upward and backward to fling the seeds from the mother plant. The seed surface is reticulated. The root system consists of a dark stout rootstock that produces rhizomes; it is high in tannins. This plant often forms colonies.
Cultivation: The preference is light shade to partial sunlight, moist to slightly dry conditions, and rich loamy soil with abundant organic matter. This plant also tolerates full sunlight if there is sufficient moisture in the soil. It is one of the easier woodland species to cultivate. Range & Habitat: The native Wild Geranium is a common plant of woodlands that occurs in all counties of Illinois (see Distribution Map). Habitats include both floodplain and upland woodlands, savannas, meadows in wooded areas, semi-shaded seeps, and rocky glades. Sometimes it invades hill prairies from adjacent wooded areas. Wild Geranium is a typical species of mesic deciduous woodlands.
Faunal Associations: The nectar and pollen of the flowers attract bumblebees, mason bees (Osmia spp.), cuckoo bees (Nomada spp.), long-horned bees (Synhalonia spp.), Halictid bees (Lasioglossum spp., etc.), Andrenid bees (Andrena spp.), and other bees. An Andrenid bee, Andrena distans, is a specialist pollinator (oligolege) of Wild Geranium (Geranium maculatum). The flowers also attract Syrphid flies, dance flies (Empis spp.), butterflies, and skippers. Other insects feed on the leaves and other parts of Wild Geranium. This includes leaf-mining larvae of the beetle Pachyschelus purpureus, Acyrthosiphon malvae (Geranium Aphid) and Macrosiphum geranii (Wild Geranium Aphid), Metriorrhynchomiris dislocatus (Yellow Plant Bug), burrowing bugs (Sehirus spp.), stink bugs (Euschistus spp.), and ebony bugs (Corimelaena spp.). The caterpillars of some moths species also feed on Wild Geranium and other Geranium spp., including Lacinipolia lorea (Bridled Arches), Heliothis virescens (Geranium Budworm Moth, Tobacco Budworm Moth), and Archips purpurana (Omnivorous Leafroller Moth). Among vertebrate animals, the Eastern Chipmunk sometimes eats the seeds, while the White-tailed Deer occasionally browses on the foliage.
Photographic Location: A flower garden at Crystal Lake Park in Urbana, Illinois, and Busey Woods in the same city. Comments: The Wild Geranium (Geranium maculatum) is the showiest of the native geraniums in Illinois with flowers at least 1" across. All of the others are far less showy because they have smaller flowers. There is a European species, Geranium pratense (Meadow Geranium), with equally large flowers, but it has not been observed in the wild in Illinois. This species has a similar appearance to the Wild Geranium, except that the hairs on its flowering stalks and pedicels are sticky-glandular, and its leaves are more divided and finely cut. Another European species, Geranium sanguineum (Long-Stalked Geranium), is rarely observed as a naturalized plant in Illinois. It has flowers with notched petals and its leaves are smaller in size.

Description: This sub-shrub is 3–8" (5–20 cm.) tall. It has ascending semi-woody stems that are sparingly branched. These stems are light green to bright red and more or less terete; they are sparsely to moderately covered with appressed white hairs. Alternate evergreen leaves occur along these stems. The leaves are ¾–2" (2–5 cm.) long and about one-third to one-half as much across; they are elliptic, ovate, obovate, or oval in shape. The margins of the leaves are sparsely serrated with bristly teeth. The upper leaf surface is medium to dark green, hairless, and shiny, while the lower leaf surface is light green, hairless to sparsely appressed-hairy, and dull. Leaf texture is somewhat stiff and leathery, while leaf venation is pinnate. The petioles of the leaves are light green to bright red and less than ¼" (6 mm.) long; they are sparsely to moderately covered with appressed white hairs. The foliage of this sub-shrub has a minty (or wintergreen) fragrance, especially when it is crushed. Either solitary or short racemes of 2-5 nodding flowers develop from the upper leaf axils. Each flower is about 1/3" (8 mm.) in length, consisting of a white bell-shaped corolla (sometimes tinted pink) with 5 short outwardly curled lobes, a white calyx with 5 ovate-oval lobes, 5 inserted stamens, and a pistil with a single stout style. The calyx is much shorter than the corolla. At the base of each flower, there is a pair of tiny ovate to heart-shaped bracts; these bracts can be light green, white, or red, and they have membranous margins. The pedicels of the flowers are up to 1/3" (8 mm.) in length, light green to red, and more or less terete; they are sparsely to moderately covered with appressed white hairs. The blooming period occurs from early to mid-summer, lasting about 3 weeks. The flowers are reported to be fragrant. Afterwards, fertile flowers are replaced by berry-like fruits that become mature during late summer or early autumn. Mature fruits are about 1/3" (8 mm.) or slightly more across, bright red, and globoid in shape; they have a fleshy interior that is slightly sweet and minty (wintergreen) in flavor. Each fruit contains many tiny seeds. The root system has shallow rhizomes, from which clonal subshrubs develop. The evergreen foliage becomes reddish or purplish during the autumn.
Cultivation: The preference is partial sun to light shade, moist to dry-mesic conditions, relatively cool temperatures, and somewhat acidic soil containing either sand or loam with decaying organic matter. Growth and development are relatively slow. Flowers and fruits are more likely to be produced in brighter locations. The seeds are difficult to germinate. Range & Habitat: Wintergreen (Gaultheria procumbens) is native to northern Illinois, where it is rare and state-listed as 'endangered' (see Distribution Map). Elsewhere within the state, it is absent from natural areas. Wintergreen occurs primarily in the Great Lakes region, northeastern USA, and adjacent areas of Canada; it also occurs in the Appalachian mountains in high-altitude areas. In Illinois, the habitats of this sub-shrub are largely restricted to upland oak woodlands, wooded hillsides, forested bogs, and shrubby bogs. In more northern areas, it is often found in coniferous woodlands, mixed woodlands, and shrubby meadows. Wintergreen occurs in high quality natural areas in Illinois. It is easily topkilled by wildfires, although the thinning of the tree canopy and reduction of taller shrubs can cause populations of this sub-shrub to increase.
Faunal Associations: Bumblebees are the primary pollinators of the flowers. Other floral visitors include cuckoo bumblebees (Psithyrus spp.) and the honeybee. Nectar is the primary floral reward for these insect visitors (Mirick & Quin, 1981; Reader, 1977; Lovell, 1898). Other insects feed on the plant sap or foliage of Wintergreen (Gaultheria procumbens). These species include an aphid (Illinoia borealis) and larvae of two moths, Cameraria gaultheriella and Rhopobota naevana (Blackman & Eastop, 2013; Ferguson, 1975; Needham et al., 1928). Birds and mammals also use Wintergreen as a source of food. The Ruffed Grouse eats the buds, leaves, and fruits; the Bobwhite Quail, Ring-necked Pheasant, and the extinct Passenger Pigeon eat (or ate) the fruits (Bennetts, 1900; Martin et al., 1951/1961; Coladonato, 1994; Schorger, 1955). This sub-shrub provides protective cover for the nests of the rare Kirtland's Warbler in Jack Pine barrens in the state of Michigan (Buech, 1980). Mammals feeding on this sub-shrub include the American Black Bear (leaves & fruits), Red Fox (fruits), Eastern Chipmunk (leaves & fruits), Elk (leaves & twigs), White-tailed Deer (leaves & twigs), Deer Mouse (fruits), and White-footed Mouse (fruits); see Coladonato (1994), Martin et al. (1951/1961), Schneider et al. (2006), Hamilton (1941), and Schloyer (1976) for more information. Fruit-eating birds and mammals spread the seeds to new locations.
Photographic Location: A flower garden at the Urbana Free Library in Urbana, Illinois, and a wooded hillside at the Pine Hills Nature Preserve in west-central Indiana. Comments: The most striking characteristic of this plant is the mint (or wintergreen) fragrance of its crushed leaves, from which oil of wintergreen is made. Even without flowers or fruits, Wintergreen (Gaultheria procumbens) can be identified by the size, shape, and fragrance of its leathery evergreen leaves. Another species in this genus, Creeping Snowberry (Gaultheria hispidula), is found north of Illinois in more boreal areas. Its crushed leaves have the same wintergreen fragrance, but Creeping Snowberry differs from Wintergreen by its prostrate habit of growth, white berry-like fruits, and smaller leaves. Other similar species in the Heath family (Ericaceae) are either larger shrubs or their leaves lack the wintergreen fragrance. Other common names of Gaultheria procumbens are Teaberry and Checkerberry.

Description: This herbaceous perennial plant is 1-3' tall, branching occasionally. The slender stems have a tendency to sprawl; they are light green to reddish green, angular, and strongly ridged. Usually, there are a few short hairs that provide the stems with a slightly rough texture. At intervals along the stems, there are whorls of 6 sessile leaves. These leaves are up to 2½" long and ½" across; they are oblanceolate in shape, while their margins are smooth and ciliate. Each leaf abruptly tapers to a short pointed tip (cuspidate). Occasionally, 1-3 stalks of flowers develop from the middle to upper whorled leaves; these stalks are often longer than the leaves, and they can be axillary or terminal. Each of these stalks may produce 1-3 flowers on slender pedicels. Each flower spans about 1/6" (4.5 mm.) across, consisting of 4 greenish white to white petals, 4 stamens, and a bristly 2-celled ovary. Each petal tapers to a narrow tip. The blooming period occurs during the summer for about 2 months. Each flower is replaced by a bristly 2-celled carpel; each globoid cell contains a single small seed. The cells of the carpel eventually separate. The root system produces rhizomes. This plant can spread by reseeding itself, or by forming vegetative offshoots from the rhizomes. Cultivation: The preference is light shade to partial sun, moist conditions, and a fertile loamy soil.
Range & Habitat: The native Sweet-Scented Bedstraw occurs in most areas of Illinois, where it is occasional to locally common (see Distribution Map). Habitats include moist to mesic deciduous woodlands, rocky bluffs, areas along woodland paths, thickets, moist meadows, partially shaded seeps and springs, partially shaded riverbanks, and bogs. In badly degraded woodlands, this plant is replaced by Galium aparine (Cleavers). Faunal Associations: The flowers are occasionally visited by small bees or flies; these insects usually suck nectar. The caterpillars of several moths feed on Galium spp. (Bedstraws), including Lobocleta ossularia (Drab Brown Wave), Epirrhoe alternata (White-Banded Toothed Carpet), and Hyles gallii (Galium Sphinx). Other insect feeders include larvae of Dasineura americana (Bedstraw Midge), larvae of the sawfly Halidamia affinis, and the polyphagous aphid Abstrusomyzus phloxae. Deer usually leave the foliage alone. The bristly carpels of Sweet-Scented Bedstraw can cling to the fur of animals and the clothing of humans; by this means, the seeds are distributed to new locations.
Photographic Location: Along a woodland path in a moist area of Busey Woods in Urbana, Illinois. Comments: The common name refers to the vanilla scent of the dried foliage. Sweet-Scented Bedstraw is typically found in moist woodlands. It can be distinguished from other Galium spp. (Bedstraws) by considering the following set of features: 1) there are 6 leaves per whorl, 2) the carpels are bristly rather than glabrous, 3) the leaves are oblanceolate with short pointed tips, and 4) the petals of the flowers taper to narrow tips. Sweet-Scented Bedstraw is one of the larger Bedstraws and its stems can be smooth or slightly rough. Its appearance is similar to Galium aparine (Cleavers), although the latter is an annual plant that occasionally produces 8 leaves per whorl and its bristly stems and leaf margins are more likely to cling to adjacent objects.

Description: This perennial wildflower is 4-20" tall at maturity, developing weak branching stems that have a tendency to lean on adjacent vegetation as they become longer. These stems are light green, angular, and branched; their edges are either smooth or slightly rough from short bristly hairs. Along the stems, there are whorls of mostly 6 leaves; often there are whorls of 4 leaves immediately below the cymes or panicles of flowers. Individual leaves are up to ¾" long and 1/8" (3 mm.) across; they are linear-elliptic in shape with short bristly hairs along their margins. The upper leaf surface is medium to dark green, hairless, and shiny. The leaves are sessile at their bases, while their tips are either blunt or acute. The upper stems terminate in either small cymes or large panicles of flowers; the size of an inflorescence is variable depending on the size of the plant and environmental conditions. Each inflorescence is abundantly branched, terminating in groups of 2-3 flowers on short divergent pedicels. The pedicels of the flowers are light green, angular, and hairless. Each flower is about 1/8" across or a little less, consisting of a white corolla with 4 pointed lobes, 4 stamens, 2 styles, and a 2-celled ovary that is without bristles. Each cell of the ovary is globoid-ovoid in shape and joined together with the other cell along one side. The blooming period occurs during early summer, lasting about 2-3 weeks. The flowers are later replaced with smooth 2-celled fruits that change color from light green to purple and finally brown. Each cell of the fruit usually contains a single seed (or sometimes none). The root system is fibrous and rhizomatous. Small colonies of plants often develop from the rhizomes.
Cultivation: The preference is medium shade to dappled sunlight, mesic to dry conditions, and soil containing loam, clay-loam, sand, or rocky material with decaying organic matter. This bedstraw is more tolerant of dry conditions than most species in its genus. It could be cultivated as a ground cover underneath trees. Range & Habitat: The native Shining Bedstraw is common throughout Illinois (see Distribution Map). Habitats include rich mesic woodlands, upland woodlands, open rocky woodlands, sandy woodlands, upper slopes and tops of bluffs, shaded cliffs, and woodland edges. Generally, this bedstraw is found in upland wooded areas where deciduous trees, especially oaks, are present. Faunal Associations: The small flowers are cross-pollinated by small bees and flies, including Masked bees (Hylaeus spp.), Halictid bees (Lasioglossum spp.), and Syrphid flies. These insects suck nectar from the flowers. Other insects feed on the foliage, flower tissue, or plant juices of Galium spp. (bedstraws). These insect feeders include the caterpillars of such moths as Epirrhoe alternata (White-Banded Toothed Carpet), Lobocleta ossularia (Drab Brown Wave), and Hyles gallii (Galium Sphinx). Another insect, Myzus cerasi (Black Cherry Aphid), uses bedstraws as summer host plants. Because the stiff bristly hairs of the leaves can cling to passing objects, animals may play a minor role in distributing the seeds to new locations. Photographic Location: The photographs were taken at a wooded bluff in east-central Illinois and the edge of a sandy woodland in NW Indiana. Comments: Shining Bedstraw can be identified by its attractive shiny leaves in whorls of 6, its smooth fruits, and its preference for upland wooded locations.

水晶掌小巧玲珑，好似用翡翠雕成的一朵小小莲花，因此被誉有有生命的工艺美术品，多摆在案头陈设，令人玩味无穷。 在日常养护中相信很多花友都遇到过水晶掌叶子腐烂的情况，这多半是因浇水与施肥不合理所造成的。下面就来具体分析一下。
水晶掌叶子腐烂 水晶掌喜好湿润的环境，但是浇水过多，会造成根部的腐烂，进而延伸到叶子部位，使叶子发黄逐渐腐烂枯萎。 当施肥过多的时候，也会灼伤水晶掌的根系部位，影响叶子的生长发育，使叶子因为缺乏根部提供的养分而逐渐枯萎腐烂。 解决办法 一定要注意浇水控制，在气温干旱炎热的季节，可以浇足够的水分，但是不要积水在盆土里；还可以时常在叶子表面喷洒水珠，保持叶子的湿润、光泽。 冬季注意一定要少浇水，盆土不干或者没有干透就不要浇水。 施肥要按植株的生长状况来界定，植株生长小且慢。可以施肥多一点，但不要过多，施肥以后就可以浇水，施肥料能够稀释，也好帮助植株吸收。 植株生长快也要施肥，保证养分的提供，总的来说施肥不要过多，更不可以施生肥，保护根部的健康生长。
水晶掌叶子颜色暗淡 水晶掌喜好温暖而湿润及半荫的生长环境，尤其注意要通风，以便叶子可以呼吸新鲜空气。 当因为通风不良，再加放置在很阴凉，没有光照的地方，就会导致其叶子出现颜色变暗淡的情况，及其影响植株的美观程度。 解决办法 注意在早晨以及夜晚阴暗的时候要放置在有光照的地方，有助于叶子生长发育； 在中午光照强烈的时候，要移动到半阴凉的地方，注意遮光，以免灼伤叶子，使叶子颜色渐变暗淡。 平时要注意通风，但不要直对风口，通风时间一般不超过2小时每天。
