[图片]一、种子从何处来 如果想要用种子进行种植，那就必须准备好种子，那种子去哪里找呢，这个其实是很简单的。 可以等到它的花落了之后，从它的花序上采摘种子。尽量选那些颗粒较饱满的种子，这样就可以提高种子出芽率。 另外有的人嫌麻烦也可以直接去花卉市场购买，购买时一定要选好了，尽量不要选到那些坏种或者是不怎么饱满的种子，不然就算种下去也难以发芽。 二、种子处理 选好种子之后，就需要将种子稍微的处理一下。 一般都是将它的种子放在水里面泡上4到6个小时，让它能够充分的吸收水，这样子就可以涨起来，变得非常饱满。泡完了之后，再稍微晾一下就可以进行播种了。 [图片]三、播种时间 因为是用种子播种，播种时间也变得很重要。 一般选择在春天到夏天的这段时间最好，因为这时候的温度比较适宜，尤其是温度在22到28度时，它的种子发芽率会更有所提高。 四、怎么种 我们取来种子，把它均匀的埋在已经准备好的土壤里，埋入的深度不能太深，要稍浅，大约1厘米厚就可以了。然后就要时刻让土壤是湿润的，这样子过上30天左右就可以发芽了。 五、播种后的养护 再把种子播种完之后，我们就可以开始进行适当的养护了。当发现土壤稍微有点干的时候，一定要及时的给它浇水，让它的土壤保持湿润。 另外还不能让它受到强光的直射，尽量放在通风好和阴凉的地方。大约过上一个月，它就会开始生根，这时候就代表着它已经成活了。

[图片]一．缘由 1如果要解决这种植物不开花，那么首先要找出来到底是什么缘由导致它不开花。它的成长地阳光不够充足。 2它的成长扎根的土不能符合它的习性提供它所需要的养分。 3没有可供它攀爬的架子。 4水肥不够。 5没有给它做好保暖的措施。 [图片]二．解决方法 1因为这种植物好光，喜欢朝向太阳的环境，所以一定要安排一个能够没有太多遮挡，能够让它好好的享受太阳的地方种植。 2种植的土一定要符合它的要求，因为它喜欢肥沃的、湿润的、酸性的土，而且土最好是含有有机质，排水性要非常好，如果泥土的酸碱度不对，那么我们可以在浇灌的水中人为地加入硫酸亚铁补充植株成长的要求,少加点就行。 3因为这种植物是一种攀援的藤本的植物，会长出卷须，而且它必须要有物体来借助它攀爬成长。无论是为了美观需要还是为了种植需要，我们都可以给它搭一个架子，或者说搭一个棚，让它可以自由地攀爬汲取光照。 [图片]4因为这种植物的成长速度非常快，它孕育的花蕾又多，花期又非常地长，如果水分和肥料不够充足的话，就不能够结出一串串硕大的花苞，所以在它的成长期要每个月都给它施一次肥料，最好是在网上购买或者是从花农处购买一些腐熟稀薄的豆饼混水浇在种植植株的土层上面。还要保持泥土的一定的湿润，淋水的次数可以观察土层的湿润情况。在夏天除了要按时淋水，对于枝叶还要保持每天2到3次的喷水，同时向地面洒水以提高空气的湿度。在花朵孕育的时候最好能够补充一次氮肥。 5这种植物非常不能够抵抗寒冷，所以在北方的冬天要把它移植到屋子里面过冬，还要接触阳光，这个时候要控制淋水的量，不要施肥，室内的温度要保持在10度以上。

[图片]分株 这个方法除了冬天，其他时候都是能进行的。因为冬天的温度过低，不适合幼株的成活，不过这种方法也是比较简单的。母株上本来就可以自己发出蘖枝，直接把这个蘖枝拿下来就可以了。如果每棵上面能带2-4个芽就更好了，不然很难成活。等切口稍微干燥一点之后，就可以直接栽在盆里了，但是开始还是要在荫蔽一点的地方养护一段时间，这样就能转入正常管理了。 播种 如果是还没有开始种植的友友，可以选择播种。这个方法可能相比之下耗时会比较长，但是也并不困难，一般选择在早春的时候进行，种子上面盖的土不用太厚，温度保持在15-18℃就可以。这样大约等待3-5周时间就可发芽，发芽之后若是长出1-2片真叶，就可以移植了。移植之后基本上就能正常养护了。 扦插 这个办法需要在生长季节进行，因为这个时候是它们汲取养分能力最好的时候，成活的机会是比较大的。但时间也不是完全不能调节，基本上4-9月都可以。剪掉2-5cm长度的插穗，要把剪口晾干，这时有条件的花友可以稍微涂一点生根粉，这样既不会伤害植株还能让它们更爱成活。然后就可以把插条直接插进土里，刚插好的那一刻一定要浇足水，这样可以使插条和基质更好的结合，插枝的成活情况也会更好。

[图片]1.是否适合水培 是可以水培的。 在平时的时候，我们经常看到球松会被种植在盆土里面进行养护，它的萌发非常的强，特别容易萌发出来一些侧芽，在养护的时候一定要注意修剪。它主要被常常用来欣赏叶子，开出来的花并不是特别好看，因此在出现花序的时候一定要及时的剪掉。这样才能让它的植株长得更好，观赏起来效果也更佳。其实除了用盆土养护，它还是可以换种方法的，比如水培，也是非常不错的。 [图片]2.怎么操作 水培的时间：如果你要对自己的球松水培的话，最好把时间选择好，一般都是在春秋两个季节来进行，这个时间是它进行水培的最佳时期。不管是温度还是湿度上面都是非常适合的。 插穗选择：在水培的时候，我们一定要选择好插条，一般都是选择那些比较健壮、没有病害的枝条，这样才能有利于它水插之后更好养护，观赏效果也非常不错。另外在水插之前还要把准备好的插条放在凉爽通风的地方，让它晾干，一般只要2到3天就可以，让它伤口充分干燥就可以了。 [图片]修剪根系及其他：球松在水中的根系是水培观赏的特色，通常是不怎么进行修剪的，免得不好看了。但是随着时间的变长，根系就会长得太密太长，还是要给它适当的将老根给删除了，长的跟剪短就行，这样就可以促进它萌发出来新的根，增强根系的活力。还有。如果水温太高造成的根系烂掉，一定要及时把烂根剪去，还要进行换水。 [图片]换水时间：进行水培的话，就需要经常的给它换水，但是不同的季节，换水隔时间也是不一样的。在夏天的时候需要3到5天换一次水，如果是在春秋的话，就要5到7天换一次，到了冬天就可以10到15天换一次就可以了。另外每次换水的时候，只要是原来瓶子水的一半以上就可以了。

[图片]白晶菊的特点 首先，我们需要了解这种植物的习性，这样我们才能知道它冬天的需要。首先，它适合相对温润的环境，在冬天，即使水不必浇太多，但是温度是不能不顾的。另外，它喜欢温暖阳光的照射，在冬天对阳光的需求自然更多。还有，它对土壤中的养分也有一定需要，不然无法支持它顺利过冬。了解了这些，我们大概就可以得知冬天的禁忌事项了。 具体的禁忌 温度过低：其适合的温度在十五到二十五度这一范围。即使冬天不能保证在这个范围之内，也不能在零下五度之下。不然，植物的叶片就会受到冻伤，既而干枯并且变黄。所以，冬天我们不能将它遗忘在室外不管不顾，一定要将它放在屋中过冬。 荫蔽过度：因为上面我们说过它对阳光的需要是非常多的。另外，因为是冬天，所以阳光对它过冬来说就更加重要了。植物冬天一般会在室内过冬，但是也不能忘掉光照这个因素，一定要将它放在阳光能照射到的地方。 浇水过多：虽然这种花总体对水分的不少，但是因为是冬天，成长发育基本处于停滞的状态，所以对水分的需求也会相应减少。所以，冬天最忌水分过多，不然植物可能会出现根部腐烂的现象。 土壤过于贫瘠：虽然植物对于土壤的要求并不是太苛刻，但是较肥沃、疏松的沙质土对它越冬来说是更适合其的选择。

Description: This perennial herbaceous wildflower is 1-3' tall and semi-erect to erect in habit. Its stems are light green to purplish brown, angular or terete, glabrous, and sometimes glaucous. Alternate compound leaves occur along these stems at intervals; they are widely spreading to ascending and evenly pinnate. Each compound leaf consists of 4-10 pairs of leaflets along a rachis (central stalk) that is light green to purplish brown and glabrous. The tip of each compound leaf terminates in a branched tendril that can cling to adjacent vegetation, fences, and other objects. [图片]Individual leaflets are 1-2" long and ½-1¼" across; they are oval-ovate in shape, smooth along their margins, and glabrous. The upper leaflet surface is medium green, while the lower surface is pale green. Each leaflet has a short narrow petiole at its base that connects to the rachis of the compound leaf. Where each compound leaf joins the stem, there is a pair of leafy stipules about ½-1" in length. Each stipule is half-cordate in shape, forming a rounded basal lobe, where there are 1-3 small secondary lobes with blunt tips. Narrow racemes of 5-12 flowers (about 2½-5" in length) are borne on long naked peduncles that are shorter than the compound leaves. Individual flowers are ½-¾" long, consisting of 5 white or cream-colored petals, a light green to nearly white tubular calyx with 5 teeth, several hidden stamens, and a pistil with a single style. Each flower has aDistribution Map typical pea-like floral structure, where one upper petal forms the banner (or standard), 2 lateral petals form the wings, and 2 petals form the keel that is enclosed by the wings. The pedicels of the flowers are short and narrow. The blooming period occurs from late spring to mid-summer. Each flower is replaced by a 2-valved seedpod that becomes 2-3" long at maturity. Each seedpod is cylindrical, somewhat flattened, and glabrous, tapering at its tip into a curved beak. When they are fully mature, the seedpods divide into 2 parts to release their seeds. The root system is fibrous and rhizomatous. Cultivation: The preference is partial sun, moist to dry conditions, sandy or rocky soil with some organic matter, and relatively cool temperatures during the summer. Range & Habitat: Pale Vetchling is native to Illinois, where it is uncommon and state-listed as 'threatened.' It is found primarily in northern Illinois, although there are a few isolated populations in the southern part of the state. This wildflower is more common in areas lying north of the state. Habitats include upland woodlands, upland savannas, sandy bluffs, wooded slopes, the slopes of rocky ravines, and riverbanks. In Illinois, Pale Vetchling often occurs where oak trees are dominant. Faunal Associations: The flowers are pollinated by bumblebees and other long-tongued bees, where they seek nectar and pollen. The caterpillars of the butterfly Glaucopsyche lygdamus (Silvery Blue) sometimes feed on vetchlings (Lathyrus spp.), although they are more often found on Vetches (Vicia spp.); this insect has a boreal range that is similar to Pale Vetchling. An aphid, Nearctaphis crataegifoliae, and other aphids may feed on this plant as well. The Ruffed Grouse sometimes eats the seeds and foliage of vetchlings. Photographic Location: A woodland in NE Illinois. The photograph was taken by Tobin Fraley (Copyright © 2010). Comments: Pale Vetchling is one of several Lathyrus spp. (vetchlings) in Illinois. Sometimes it is referred to as 'Cream Pea' or 'Cream Peavine.' This species can be distinguished from others in this genus by its white or cream-colored flowers, relatively broad leaflets, and distinctive stipules, which have rounded basal lobes with one or more secondary lobes. Other species in this genus often have purple-lavender flowers, narrow leaflets (less than one-third as wide as long), and their stipules lack secondary lobes. Pale Vetchling would probably be adaptable to cultivation in partially shaded gardens.

Description: This biennial wildflower forms a low rosette of leaves about 8-12" across during the first year. During the second year, it bolts and becomes 2-7' tall. Usually, this wildflower is unbranched, although sometimes ascending lateral branches develop along the upper one-third of a large plant. The central stem (and any lateral stems) is rather stout, terete, and light green to pale purple; it is usually hairy along the lower half of its length, becoming hairless and slightly glaucous along the upper half. The alternate leaves are up to 6" long and 2" across, becoming gradually smaller as they ascend the stem; they are pinnatifid with pointed irregular lobes and dentate along their margins. The upper surfaces of these leaves are medium green and often sparsely hairy; their lower surfaces are pale green and hairy, particularly along the midribs. The basal leaves are similar to the alternate leaves, except they tend to be larger in size and more wide toward their tips (narrowly obovate to obovate). Young developing basal leaves are usually very hairy on both their upper and lower surfaces. The central stem (and any lateral stems) terminates in an elongated panicle of flowerheads about 6-12" long and 2-4" across. The branches of the panicle are light green to reddish purple, terete, and usually hairless. Each flowerhead is about 1/3" (8-10 mm.) across when fully open, consisting of 12-25 ray florets, no disk florets, and light green to purple floral bracts that are arranged in about 3 series around its base (involucre); this base is about 2/3–3/4" (15-20 mm.) long. The rays of the flowerhead are colored salmon to brick-red and their tips are truncate and finely toothed. The outer floral bracts are shorter than the inner floral bracts. [图片]The blooming period occurs from mid-summer to early fall and usually lasts about 3 weeks. Individual flowerheads last only a single day, blooming for only a few hours on sunny days. After only a short period of time, individual flowerheads are replaced by small black achenes with tufts of white hair. Each achene is 4-5 mm. long, ellipsoid-oblanceoloid in shape, and flattened; the tuft of white hairs is attached to the achene by a slender white beak about 2.5–3.5 mm. long. These achenes are distributed by the wind. The root system consists of a taproot. This wildflower reproduces by reseeding itself. Cultivation: The preference is partial sun, mesic to dry conditions, and somewhat acidic sandy or rocky soil. The size of individual plants is highly variable, depending on moisture levels and soil fertility. [图片]Range & Habitat: Red-Flowered Wild Lettuce is a rare native plant in Illinois and it is state-listed as 'endangered.' Thus far, this species has been collected from a single county in southern Illinois (see Distribution Map). Because this species can be confused with other Lactuca spp., it may occur in other areas of the state. Outside of Illinois, this species is also uncommon. Habitats include upland rocky woodlands, woodland openings, woodland borders, upland savannas, sandstone glades, pastures, and abandoned fields. These habitats also include sandy areas. Red-Flowered Wild Lettuce prefers some disturbance to reduce the abundance of woody vegetation. [图片]Faunal Associations: Little is known about floral-faunal relationships for this particular species. The flowerheads are probably cross-pollinated by various bees (medium- to small-sized), which offer nectar and pollen. In general, the caterpillars of some moths feed on Lactuca spp. (Wild Lettuce species), including Autographa precationis (Common Looper Moth), Grammia virgo (Virgin Tiger Moth), and Cucullia intermedia (Intermediate Cucullia). The caterpillars of the last moth species feed on the flowerheads. Other insect feeders include Thrips physapus (Dandelion Thrips) and several aphid species: Hyperomyza lactucae (Currant-Sowthistle Aphid), Nasonovia ribisnigri (Currant-Lettuce Aphid), Pemphigus bursarius (Lettuce Root Aphid), Prociphilus erigeronensis (White Aster Root Aphid), Uroleucon ambrosiae (Brown Ambrosia Aphid), Uroleucon gravicorne (Aphid sp.), Uroleucon pseudambrosiae (False Ambrosia Aphid), Uroleucon rudbeckiae (Golden Glow Aphid), and Uroleucon sonchella (Sowthistle Aphid). Among vertebrate animals, the Eastern Goldfinch eats the seeds, while White-Tailed Deer occasionally graze on the foliage of Lactuca spp. Photographic Location: The wildflower garden of the webmaster in Urbana, Illinois. [图片]Comments: This unusual species has been sadly neglected from many wildflower field guides. Although it has an extensive range in the eastern half of the United States, Red-Flowered Wild Lettuce appears to be uncommon to rare in most areas. The preceding description applies to var. sanguinea, rather the typical variety. In other areas of its range, Lactuca hirsuta may have yellow flowerheads and the hairiness of its stems and leaves can be variable (from nearly hairless to very hairy). Red-Flowered Wild Lettuce can be easily confused with the more common Lactuca canadensis (Common Wild Lettuce), which is itself a rather variable species. Generally, Common Wild Lettuce has flowerheads that are pale yellow to dull orange, flowerheads with shorter bases (involucres) that are ½" or less, and shorter achenes (less than 4 mm. long). Common Wild Lettuce is usually completely glabrous (except for some hairs along the lower midribs of its leaves), and its upper stems and floral branches are usually less purple. Another species, Lactuca biennis (Tall Blue Lettuce), has light blue to cream-colored flowerheads and its achenes have shorter beaks and tufts of tawny or gray hair, rather than white hair. These different Lactuca spp. cannot be identified reliably unless the flowerheads or tufted achenes are available for examination. Another common name of Lactuca hirsuta is Hairy Wild Lettuce.

Description: This perennial wildflower consists of a rosette of basal leaves, from which a flowering stalk about 1-2' tall is produced. The basal leaves are up to 7" long and 2" across; they are pale green to green, hairless, and oblanceolate or obovate in shape. Their margins are smooth, undulate, slightly dentate, or slightly pinnatifid. The flowering stalk is pale green, hairless, glaucous, terete, and erect. There are 1-2 cauline leaves on the flowering stalk that are ovate in shape and smooth or dentate along their margins. Where the uppermost cauline leaf occurs, the stalk branches into 2-5 ascending peduncles. Each peduncle terminates in a yellow or orange-yellow flowerhead about 1–1½" across. Each flowerhead has many spreading ray florets and no disk florets. Each ray floret is narrowly oblong and yellow or orange-yellow; it has a truncate tip with 5 small teeth. The base of the flowerhead is surrounded by several floral bracts in a single series; each bract is pale green, linear-lanceolate, hairless, glaucous, and about 1/3" (8 mm.) in length or a little longer. The blooming period can occur from late spring to mid-summer and lasts about a month. Later in the year, the ray florets are replaced by small achenes. Each achene is bullet-shaped and truncate at the apex, where it has a tuft of white hairs. The achenes are distributed by the wind. The root system consists of a thickened crown with fibrous roots. [图片]Cultivation: The preference is partial or dappled sunlight and mesic to dry conditions. Different kinds of soil are tolerated, including those containing loam, clay-loam, sand, or rocky material. Water-logged sites should be avoided. Range & Habitat: The native Two-Flowered Cynthia is occasional to locally common throughout Illinois (see Distribution Map). Habitats include open upland woodlands, open sandy woodlands, savannas and sandy savannas, rocky wooded slopes, thinly wooded bluffs, areas along woodland paths, rocky glades, and upland meadows. Two-Flowered Cynthia is often found in upland habitats where Oaks are dominant in areas with thin leaf cover and sparse ground vegetation. Faunal Associations: The flowerheads attract long-tongued bees (bumblebees, honeybees, Little Carpenter bees, Cuckoo bees, Mason bees), short-tongued bees (Halictid bees, Masked bees), predatory wasps, flies (Syrphid, Tachinid, & others), butterflies, skippers, and beetles. These insects suck nectar, collect pollen, or feed on pollen from the flowerheads. An oligolectic visitor, Andrena krigiana (Krigia Andrenid Bee), is specifically attracted to the flowerheads of Krigia spp. In addition to these floral visitors, an aphid, Uroleucon brachychaetum, sucks plant juices from these plants. Thus far, I have not observed any evidence that White-Tailed Deer feed on the foliage of Two-Flowered Cynthia, which contains a bitter white latex, although I would not rule out this possibility. Photographic Location: The photographs were taken along the edge of two wooded bluffs in Vermilion County, Illinois. Comments: The flowerheads and foliage of this wildflower are quite attractive. Most members of the Aster family with dandelion-like flowerheads (including other Krigia spp. in Illinois) have yellow ray florets, but the ray florets of Two-Flowered Cynthia often have an orange tint. Two-Flowered Cynthia has larger flowerheads (1" across or more), longer floral bracts (1/3" or more), and its achenes have more bristly hairs (20 or more) than either Krigia virginica or Krigia caespitosa (both annuals). Another species, Krigia dandelion (Potato Dandelion) has unbranched flowering stalks that each produce a single flowerhead. In contrast, Two-Flowered Cynthia has flowering stalks that branch above their uppermost cauline leaves, each stalk producing 2-5 flowerheads on separate peduncles.

Description: This herbaceous perennial plant consists of a twining vine up to 20-30' long. It will climb adjacent vegetation readily, or sprawl across the ground in open areas. The terete stems are usually hairless, but sometimes pubescent, and often reddish purple. Along the stems are alternate leaves up to 6" long and 4" across. These leaves are usually cordate and hairless, although sometimes the smaller leaves are ovate. They have long hairless petioles and smooth margins. Both the upper and lower surfaces of the leaves are olive green, while the petioles are often reddish purple. Flowering stalks develop from the axils of the leaves; each flowering stalk has a cluster of 1-5 funnelform flowers. The corolla of each flower is white, except for rosy pink or reddish purple coloration deep within its throat. The corolla has 5 shallow lobes; it is about 2½-3" across when it is fully open and similarly in length. The stamens of the flower are white; they project slightly from the throat of the corolla. The blunt overlapping sepals are light green, hairless, and about ½-¾" long; they often have narrow ridges. The flowers bloom during the morning (or during the afternoon on cloudy days), and they are individually short-lived. However, a typical plant will bloom for about 2 months during mid- to late summer. Each flower is replaced by a 2-celled capsule that contains 2-4 seeds. These flat seeds are conspicuously hairy along their outer edges, and pubescent elsewhere. The root system produces a large tuber that can lie several feet beneath the ground surface and weigh up to 20-30 lb. [图片]Cultivation: The preference is full to partial sun and mesic to dry conditions. The type of soil is not particularly important; this plant often grows where there are rocky or gravelly slopes. Growth can be rampant where the soil is moist and fertile; this plant can smother surrounding vegetation and it prefers some kind of structural support. Drought resistance is very good. Range & Habitat: The native Wild Sweet Potato occurs occasionally in most counties of Illinois, except in the extreme north and NW areas of the state, where it is uncommon or absent (see Distribution Map). Habitats include upland woodlands, edges of prairies near woodlands, rocky streambanks, thickets, fence rows, abandoned fields, and areas along railroads and roadsides. This plant is more often seen in disturbed habitats, but it can be found in higher quality habitats as well. [图片]Faunal Associations: The flowers primarily attract long-tongued bees, including honeybees, bumblebees, and digger bees (Melissodes spp.). Some oligolectic bees that visit the flowers of the Wild Sweet Potato and other Ipomoea spp. include Melitoma taurea (Mallow Bee) and Cemolobus ipomoea (Morning Glory Bee). These insects seek nectar primarily, although the oligolectic bees collect pollen as well. Less common visitors to the flowers include nectar-seeking swallowtail butterflies, skippers, and sphinx moths. Like other Ipomoea spp., Wild Sweet Potato attracts numerous tortoise beetles and other beetles that feed on the foliage. These species include Agroiconota bivittata (Striped Tortoise Beetle), Charidotella purpurata (Tortoise Beetle sp.), Charidotella sexpunctata (Golden Tortoise Beetle), Chelymorpha cassidea (Argus Tortoise Beetle), Jonthonota nigripes (Black-Legged Tortoise Beetle), Opacinota bisignata (Tortoise Beetle sp.), Strongylocassis atripes (Tortoise Beetle sp.), Chaetocnema confinis (Sweet Potato Flea Beetle), and Typophorus nigritus (Sweet Potato Leaf Beetle). Larvae of the Sweet Potato Flea Beetle and Sweet Potato Leaf Beetle also feed on the roots. Larvae of a long-horned beetle, Phaea monostigma, bore through the stems of Ipomoea spp. The caterpillars of such moths as Agrius cingulatus (Pink-Spotted Hawk Moth), Bedellia somnulentella (Sweet Potato Leaf-Miner), and Emmelina monodactyla (Morning Glory Plume Moth) also feed on these plants. Because the foliage is bitter and somewhat toxic, it is avoided by mammalian herbivores as a food source. Because its long leafy stems often form dense thicket tangles, Wild Sweet Potato provides excellent cover for birds and other kinds of wildlife during the summer and early fall. Photographic Location: The photographs were taken near an abandoned railroad in Champaign County, Illinois. The plant was growing along a gravelly slope, where it clambered over Conium maculatum (Poison Hemlock). [图片]Comments: The common name of this plant species refers to the large tuberous root, which is edible (barely) after being cooked. Another common name, Man-of-the-Earth, also refers to this large tuberous root. It was one of the food sources of native Amerindians. The Wild Sweet Potato is fairly easy to distinguish from other members of the Morning Glory family by its large white flowers with pinkish purple throats and its heart-shaped leaves. Perhaps its most unusual feature (aside from the root) is the hairiness of its seeds; other Morning Glory and Bindweed species usually have smooth seeds.
