[图片]1.浇水 浇水是影响它叶子变色的一大点，如果喷水太多它的叶子就会变颜色。它是比较喜欢排水良好的土壤的，在它生长的时候我们需要等到它干了再浇，如果没干就不要浇，不要让盆里面积水，要不然根还会烂掉。这一种植物是耐旱但是不耐涝的，所以浇水一定不能太频繁。如果浇水太多它的叶子会变成黄色，严重的时候它还会掉落。当然，我们把它放在比较阴凉通风的地方是解救它的一个大方法。 [图片]2.光照 光照也是会影响它的叶子变色与否的。它本身的颜色应当是紫褐色甚至浅褐。如果新的枝条在光下是紫红色的，那光就比较充足，假若它是绿色的，光就不太足了。因此我们要给它充足的光照，如果它待在半阴凉的地方，根茎就很容易徒长，分枝也不太好，而且变色会很明显。 [图片]3.施肥 它有自己需要的肥料。但是给它的肥料不能够太浓厚，当然也不能经常给它浇。一般情况下，我们只要等到换土之时才给它加一些。 [图片]

[图片]1.时间 这一种植物的扦插的时间宽度比较大，在每一个时间段都可以进行，只不过在春天和秋天是最好的，因为在这一个时间根的存活率比较高。 2.枝条 现在这条要稍微老一些，长的要比较好，最好是侧枝比较多。我们从上面选取待带叶子的。枝条的长度在八到十二厘米，我们要将它放在比较阴凉的地方晾干一两日，让伤口变干燥，然后把它插到沙床里面。当然，我们也可以选择主茎的叶子，等到它晾干就可以插到沙床。它生根挺快，半个月就会长出。 [图片]3.温度 温度是在二十到二十五这一个区间，这样它生根才会比较快。 4.土壤 我们要等枝条的伤口干了之后再进行后续操作，土需要比较干，所以在插上去一个星期之后是不能够给它浇水的。 [图片]5.压条 假如我们实在不会做这个，可以压条。把正长的枝条划一道小口，也需要等到伤口干，再把它压到土里固定，大概几个月之后它就会长出根来，确认它长了根之后要把枝条剪断，让它成为新的一个植株，这个是比较安全的，不过需要等挺长时间。 [图片]

[图片]1、阳光 我们想要让它开花开得好，需要的就是让它所处的环境与原产地相差无二，这虽然不简单，但是用心做还是可以的。首先我们需要做的是出了夏天之外给它一定的光照，只要有充足的光它才能够积累特别多的养分，当然光不可以过多，要不然叶子会因此萎蔫。一般的光照它还是受得了的，毕竟它的原产地光也别强。我们可以根据它新的枝条颜色来辨别它的光是否足够，如果它的光足了，新的枝条会使紫红色的，如果不足，那就是绿色的。 [图片]2、温差 温差的增大对它而言是一种促使开花的好方法，白天还有晚上的温度差别是要在湿度以上的，这样才能够让养分消耗得最少。 [图片]3.通风 通风的增强对它也有重要作用，除了低温，我们最好让它在露天的环境里，这样子风才会比较多，花才能够尽心开放。 4、施肥 施肥是必要的，如果不施加它很难长出花来。每两个星期就要给它加一次稀肥水，当然是以氮为主。 [图片]

[图片]1、检查 首先我们需要做的是检查一下植株的烂根状况，看一下情况是否严重，烂根的范围是不是太大，而且能不能继续活下去，如果能的话就可以拯救一下它，不能的话只能够选择放弃了。 [图片]2、修根 这个时候我们需要做的是将它烂掉的根剪去，烂掉的枝叶同样也要剪除。修剪的时候需要注意一下，必须要让把它修干净，而且修剪的时候可以适当往正常的枝叶延伸一下，这样子留下的就一定是没有烂掉的枝条了。 3、换盆 修剪之后，我们要看一下这个盆是不是符合它，当植株的大小与盆的大小不合适之时，我们要给它换盆。小的配小盆，大的配大盆。一定不能够将太小的苗放在太大的盆里，要不然水流失得很慢，这样子还会再烂根。 [图片]4、浇水 再给它换好盆之后，我们需要做的是控制一下浇水，不能给它浇太多水，而且时间也要控制好，如果是秋冬时节的话中午浇水是可行的，但是如果是春夏的时候还是只能够在早上和晚上进行。 5、通风 通风是必要的，尤其是当它的烂掉之后我们要确保它的通风状态，这样子它才能够好的快，而且长得也会比较好，将它放在通风不好的环境里它很难长得好。 [图片]

[图片]1.增加光照 对于金鱼吊兰来说，阳光是生长过程中必不可少的一个重要因素，在接受光照的同时，植物自身也在储蓄能量，而此植物开花前则需要充裕的阳光才能保证正常开花；它的花期是冬季，所以根部不必担心会被阳光晒伤，可以全天候的放在阳光充裕的地方摆放，这样开出的花不但数量多且花色也会非常艳丽。但其它三个季节则要适当的进行遮阳。 [图片]2.增加水分 金鱼吊兰在冬季会出现休眠的状态，但只是一小段时，这段时间过后就会开花，但此时很多人会减少浇水，其实此时应该增加浇水，只要保证盆内不出现积水现象即可，温度要控制在20度左右。这样会更容易让其开花，且会开的更加充分。除了浇水外，还要经常给植物周边或是叶子喷洒些水，过干的环境会让它掉叶，也会影响其开花。 [图片]3.增加空气流通性 冬季室内的空气流通性都比较差，这对此植物的开花来说也是会有一定影响的，尤其在其花芽生长时，若空气流通性过差，会导致它暂停生长，最终无花可开。 4.增加养分 很多友友在养花时，第一年知道按时施肥，到了第二年，就将其抛于脑后，养分不充足时，也时花芽也是无法正常生长的。开花前要增加磷肥的施放；但开花时就不要在进行施肥了。 [图片]

[图片]1.处理方法 金鱼吊兰受冻后首先将植株移到室内，把已经枯黄的叶子全部摘除，然后用20度左右的水浇灌盆土，但在浇时最好沿着花盆边缘缓缓浇入，不可直接一次性倒入，同时不可离根部太近，否则会出现反作用，让植物无法快速接受温度的变化。底部有水流出后，再浇一次即可。水温切忌不可过高。 [图片]2.增加温度 金鱼吊兰在10度以下的温度中两天便会出现受冻的现象，其叶子会先变黄。所以首先要将温度调整至15度左右，不可将温度一下由10度以下转变为22度以上，温差过大，并不利于它恢复，要循序渐进。 冬季若可以将温度维持在15度以上时，金鱼吊兰便可安全越冬；但也要注意温度不要超过28度，否则会造成它叶子枯焦。 [图片]3.增加光照 金鱼吊兰受冻后，除了增加温度外，还可以将之摆放在阳光充足的地方，因是冬季，所以无需担心它会被晒伤，而且它的花期亦是冬季，花期前后也是需要充裕的阳光，这样才可开出颜色艳丽且饱满的花朵。 [图片]

[图片]1.处理方法 金鱼吊兰徒长有两种处理方法：第一种是打顶，把其生长点除去。意思就是将枝条的顶端掐去，让其在无法生长；第二种是摘叶，把徒长的枝条上的叶子摘去2对至3对。以上两种方法都是为让其枝茎粗壮化，植物整体矮化，且保留养分给枝茎与侧芽，让其更好的生长。 [图片]2.预防方法 ①阳光：造成它徒长的原因之一便是缺光。虽说此植物的生长过程不需太多的阳光，但若长期无阳光则是很容易徒长的，春、夏、秋三个季节要适当的给些阳光，但午间的阳光要进行遮挡，而冬季可以完全放在阳光下摆放。这样便可有效的避免其徒长。 [图片]②养分：造成它徒长的另一原因便是养分。施肥过于频繁或是肥量过大也是会造成其徒长的，若已经过多施肥，那么可以暂停浇水与施肥，让植物濒临饥渴状态，这样可以让其回归正常状态。且养分过多时，对于植物开花也是有影响的。当其恢复正常后在按常规施肥，宁淡勿浓。 ③水分：其实浇水与阳光是要相配合的，若长期不见阳光，但还给它充足的水分，也是会徒长的，所以要避免给它浇太多的水。 [图片]

Description: This herbaceous perennial plant is about 4-6" tall, consisting of 1-2 basal leaves and a flowering stalk with a single flower. Immature plants produce a single leaf and fail to flower, while mature plants that bloom produce a pair of leaves. The basal leaves are up to 6" long and 2" across. They are elliptic, lanceolate, or narrowly ovate, and smooth (entire) along their margins. The upper leaf surface is mottled pale green and brownish or grayish green, while the lower leaf surface is pale to medium green. Both leaf surfaces are glabrous; the upper leaf surface is often waxy. The leaves often curve upward slightly from the midvein to the margins. A naked flowering stalk develops between the basal leaves of mature plants. This stalk is light green to reddish brown and glabrous; it nods downward at its apex, where the flower occurs. Each nodding flower is about 1½" long and across; it consists of 6 white tepals, 6 stamens with long yellow anthers, and a slender style with a stigma that has 3 lobes that spread outward. The tepals are linear-lanceolate and strongly recurved, while the stamens and style are exerted. The blooming period occurs during mid-spring and lasts about 2 weeks. Each fertilized flower is replaced by a 3-chambered seed capsule that is ovoid and about ¾" long. Each chamber of the seed capsule contains 2 rows of flattened seeds. The root system consists of a corm that is several inches below the surface of the ground; this corm produces fibrous roots at its base and occasionally sends out underground stolons that can form new plants a few inches away from the mother plant. White Trout Lily can produce large colonies of plants if it is left undisturbed for several decades. [图片]Cultivation: The preference is dappled sunlight during the spring, moist to mesic conditions, and a rich loamy soil with decaying leaf mould. Situations involving more shade are tolerated later in the year. The foliage withers away during the summer. It takes several years for a new plant to fully develop and bloom. Corms can be transplanted successfully during the fall, while the establishment of new plants from seeds is difficult and slow. Range & Habitat: The native White Trout Lily is a common plant that occurs in every county of Illinois, except for Jo Davies county in the extreme NW corner of the state (see Distribution Map). Habitats include moist to mesic deciduous woodlands and gentle slopes in wooded areas. An abundance of this plant indicates that a woodlands has never been subjected to the plow or bulldozed over. White Trout Lily is one of the spring wildflowers that is threatened by the spread of Alliaria petiolata (Garlic Mustard) in wooded areas. [图片]Faunal Associations: The flowers are primarily pollinated by both long-tongued and short-tongued bees, including honeybees, mason bees (Osmia spp.), cuckoo bees (Nomada spp.), digger bees (Synhalonia belfragii), Halictid bees (Halictus spp., Lasioglossum spp.), plasterer bees (Colletes inaequalis), and Andrenid bees (Andrena spp.). The bees suck nectar from the flowers; honeybees and short-tongued bees also collect pollen. An oligolectic bee of Erythronium spp. (Trout Lilies) is Andrena erythronii. Less typical insects visiting the flowers for nectar include the Giant Bee Fly (Bombylius major), butterflies, and skippers. Trout Lilies (Erythronium spp.) are occasionally eaten by White-tailed Deer, but the damage is usually minor because of the low stature and ephemeral nature of the foliage. Photographic Location: A deciduous woodlands at Busey Woods in Urbana, Illinois. [图片]Comments: White Trout Lily usually blooms a little earlier than other spring wildflowers in woodlands; this blooming period is short, and immature plants that don't bloom always outnumber mature plants. Both the flowers and foliage are attractive (especially if the latter is mottled). The other Trout Lilies in Illinois are less common; they include Erythronium americanum (Yellow Trout Lily) and Erythronium mesochoreum (Prairie Trout Lily). Yellow Trout Lily has yellow flowers and the lobes of its stigmas are united, rather than spreading. Prairie Trout Lily resembles a White Trout Lily with unmottled foliage. However, it produces a larger seed capsule (about 1" long) that nods downward from its stalk, sometimes touching the ground. White Trout Lily has a smaller seed capsule (about ¾" long) that remains more or less erect on its stalk. The flowers of Prairie Trout Lily are light blue-violet more often than those of White Trout Lily, and its basal leaves tend to be less broad and more strongly folded upward along their midveins.

Description: This perennial wildflower is 3-10" tall, consisting of one or more stems with alternate leaves and compound umbels of flowers. The light green to reddish brown stems are stout, longitudinal ridged, and glabrous; sometimes they are erect, but more often sprawl across the ground. The leaves are up to 5" long and 3" across; they are ternately compound (typically divided into 3 leaflets). Each leaflet is irregularly cleft into about 3 narrow lobes; these lobes are oblong, elliptic-oblong, or narrowly oblanceolate and their margins lack teeth. The blades of the leaves (i.e., their leaflets) are light to medium green and glabrous, while their long petioles are sheathed at the base. The stems terminate in compound umbels of white flowers. Each compound umbel consists of 1-4 umbellets, while each umbellet has 1-6 flowers. The flowers of each umbellet are closely bunched together because their pedicels are quite short. At the base of each umbellet, there is a small leafy bract. Each flower is about ¼" across, consisting of 5 narrow white petals, 5 stamens, a divided white style, and no sepals. The anthers of the stamens are initially dark red, but they soon turn black. The blooming period occurs from early to mid-spring and lasts about 1 month. Each flower is replaced by a slightly flattened globoid fruit (a schizocarp) that contains a single seed. The root system consists of a corm with fibrous roots. This wildflower reproduces by reseeding itself. Occasionally, it forms loose colonies of plants. Cultivation: Some dappled sunlight is required during the spring, otherwise shade is tolerated. Moist to mesic conditions and a rich loamy soil with some rotting organic matter are preferred. Most vegetative growth and development occurs during thePlant in Bloom spring. Range & Habitat: The native Harbinger-of-Spring has a scattered distribution throughout most of Illinois, but it is absent from the NW section of the state (see Distribution Map). It is occasional in some woodlands, but mysteriously absent from many others. Habitats include rich mesic woodlands with deciduous trees, wooded areas at the base of bluffs, rocky bluffs, wooded bottomland of rocky canyons, gentle wooded slopes along rivers, and areas along woodland paths. This wildflower is normally found in high quality deciduous woodlands. [图片]Faunal Associations: The flowers attract primarily small to medium-size bees and miscellaneous flies. Bee visitors include Little Carpenter bees (Ceratina spp.), Mason bees (Osmia spp.), Andrenid bees (Andrena spp.), and Halictid bees (Lasioglossum spp., Halictus spp., etc.). Fly visitors include Calliphorid flies, Anthomyiid flies, Frit flies (Chloropidae), Lance flies (Lonchaeidae), and flower flies (Syrphidae). These insects seek primarily nectar from the flowers. Photographic Location: A wooded area at the base of a bluff in Kickapoo State Park, Vermilion County, Illinois. This location is not far from an abandoned coal mine. Comments: This is one of the earliest wildflowers to bloom in our deciduous woodlands. Because of its small flowers and low growth habit, it is rather easy to overlook. Also, when observed from a distance, Harbinger-of-Spring can be confused with other wildflowers with small white flowers. Another common name is 'Pepper-and-Salt Plant,' which refers to the anthers of the flowers (after they have become black) and the bright white petals. This wildflower is fairly distinctive because of its period of early bloom, stout stems, oddly colored anthers, and tight umbellets of flowers with narrow white petals.

Description: This herbaceous parasitic plant is 4-18" tall. Small plants are often unbranched, but large plants are paniculately branched with stiff ascending stems. These stems are initially cream, tan, or purple-striped, but they turn brown with age. The surface of each stem is mostly glabrous, but sometimes it is slightly pubescent. The leaves are reduced to insignificant scales; they are located underneath some of the flowers. Along the length of the stems are alternate flowers; the lower stems have cleistogamous (self-fertile) flowers, while the upper stems have perfect flowers that are usually sterile. The cleistogamous flowers are small and bud-like in shape, while the perfect flowers have tubular corollas with short calyces. The corolla of a perfect flower is about 1/3" (8 mm.) in length, cream- and purple-colored, with 4 short lobes along its outer rim. Each calyx is cream-colored with 5 purple-striped teeth; it is much shorter than the corolla of a perfect flower. Each perfect flower has a single style and four stamens; the latter are hidden within the corolla. The blooming period occurs from late summer into the fall. There is no noticeable floral scent. Each fertile flower is replaced by a small ovoid seed capsule about ¼" (6 mm.) long; it contains numerous tiny seeds that can be blown about by the wind. The root system is fibrous. Sometimes large colonies of this plant can be found. Cultivation: This parasitic plant contains no chlorophyll and obtains its nutrients from the roots of Fagus grandifolia (American Beech). Without the presence of this tree, Beechdrops cannot survive. [图片]Range & Habitat: The native Beechdrops is uncommon in Illinois; it is found in a few counties of the southern and SE regions of the state (see Distribution Map). Illinois lies at the western range limit of both Beechdrops and the American Beech; both species are more common further to the east. Habitats include mesic woodlands and rocky wooded slopes where American Beech and Sugar Maple trees are usually codominant. Faunal Associations: Very little information is available about floral-faunal relationships for this species. The perfect flowers may be visited occasionally by long-tongued bees. The ecological value of Beechdrops to animals appears to be low. Photographic Location: A rocky wooded slope in west central Indiana where American Beech was present. [图片]Comments: From a distance, this plant looks like it is dead, even when it is in bloom, resembling an elongated skeletal hand that has poked up from the ground. When examined up-close, however, it is an interesting plant with beautiful cream and purple-striped flowers and similarly colored stems. Beechdrops is a member of a small group of parasitic plants in the Broomrape family (Orobanchaceae). None of these species are very common in Illinois, and they should be protected in the areas where they occur. Other species in this family tend to be more stout and less branched than Beechdrops; they also produce larger flowers with similar tubular corollas (exceeding ½" in length). These species don't compete directly with Beechdrops because they are parasitic on the roots of plants other than American Beech; typical hosts are oak trees and various members of the Aster family.
