Description: This annual plant is 1-4' tall, branching occasionally. It is more or less erect, often bending toward the light in partially shaded locations. The stems are light green to red, terete, relatively stout, and glabrous; they have a tendency to zigzag between the alternate leaves. The leaves are up to 7" long and 2½" across; they are medium to dark green, glabrous on both the upper and lower sides (for this variety), narrowly lanceolate to lanceolate in shape, and smooth to minutely ciliate along their margins. On rare occasions, the leaves are marked with chevrons that are faintly darkened, otherwise they are unmarked. The petioles are up to 1" long, usually light green, glabrous, and plano-convex (flattened above and convex below). At the bases of petioles, there are ring-like ochrea (membranous sheaths) that surround the stems. These ochrea are ¼–¾" long, light green to light brown (depending on their age), longitudinally veined, and translucent; their upper rims are truncate to asymmetric and devoid of bristles. The upper stems terminate in 1-2 spike-like racemes of flowers that are about ¾-2½" long and cylindrical in appearance; these racemes are usually straight and they are erect to ascending. Small flowers and flower buds are densely crowded along the entire length of each raceme, surrounding its rachis (central stalk) in all directions. Along this rachis, are ochreolae (small membranous sheaths) that are spaced at short intervals from each other; several flowers are associated with each ochreola. Each flower is 3-4.5 mm. long (1/8" or slightly longer), consisting of 5 tepals, several stamens, and a pistil. The tepals are white, light pink, or rosy pink; they are joined together along the lower one-half of their length, while their tips are ovate and erect. The anthers are white or pink. The peduncles of the racemes are ¾–3½" long, light green to reddish green, terete, glandular-pubescent, and either unbranched or dichotomously forked. Peduncles that are forked produce 2 racemes of flowers. The blooming period occurs during the summer or early autumn, lasting about 1 month for a colony of plants. There is no noticeable floral scent. Afterwards, the flowers are replaced by achenes (one achene per flower). These achenes are 2-3.5 mm. long and almost as much across; they are dark brown to black, flattened-orbicular in shape, smooth, and shiny. The root system consists of a taproot with smaller and more shallow lateral roots. Colonies of plants are often formed at favorable locations. [图片]Cultivation: The preference is full or partial sun, moist conditions, and rich loamy soil. Standing water is tolerated if it is temporary. This robust plant is rather weedy and easy to grow – it has more tolerance to drought than many other smartweeds. The leaves are rarely blemished by disease, although they are sometimes attacked by insects. Range & Habitat: The native Pennsylvania Smartweed occurs in every county of Illinois, where it is common (see Distribution Map). Habitats include wet prairies, prairie swales, swamps, low areas near ponds or rivers, edges of marshes, degraded seasonal wetlands, abandoned fields, low areas along railroads, roadside ditches, vacant lots, fence rows, and waste areas. This annual plant thrives on the reduced competition resulting from disturbance. [图片]Faunal Associations: The flowers of Pennsylvania Smartweed attract many kinds of insects, including honeybees, bumblebees, cuckoo bees (Epeolus spp., Triepeolus spp.), digger bees (Melissodes spp.), leaf-cutting bees (Megachile spp.), Halictid bees, Andrenid bees, Sphecid wasps, Vespid wasps, spider wasps (Anoplius spp.), Syrphid flies, Tachinid flies, flesh flies (Ravinia spp.), and miscellaneous butterflies and moths (Robertson, 1929). Most of these insects feed on the nectar and they help to cross-pollinate the flowers. Other insects feed on the leaves, roots, plant juices, and other parts of Pennsylvania Smartweed and other smartweeds (Persicaria spp.). These species include the Red-headed Flea Beetle (Systena frontalis) and other leaf beetles, larvae and adults of various weevils, the Polygonum Aphid (Capitophorus hippophaes) and other aphids, larvae of the Dock Sawfly (Ametastegia glabrata) and other sawflies (Ametastegia spp.), larvae of the Bent-line Carpet (Orthonama centrostrigaria) and other moths, and larvae of the Bronze Copper (Lycaena hyllus) and other butterflies. See the Insect Table for a listing of these and other species. [图片]Among vertebrate animals, the seeds of Pennsylvania Smartweed and other smartweeds are an important source of food to many bird species, including waterfowl, upland game birds, and granivorous songbirds (see the Bird Table). The seeds are also eaten by small rodents, including the White-footed Mouse and wild House Mouse (Whitaker, 1966). According to Ernst et al. (1994), several turtles feed on smartweeds (probably the foliage to a minor extent); this includes such turtles as the Snapping Turtle (Chelydrina serpentina), Painted Turtle (Chrysemys picta), Eastern Box Turtle (Terrapene carolina), and Slider (Trachemys scripta). Mammalian herbivores usually avoid the foliage of Pennsylvania Smartweed and most other smartweeds because their leaves are somewhat bitter and peppery. Photographic Location: The photographs were taken at a vacant lot near Urbana, Illinois, and a seasonal wetland at Judge Webber Park of the same city. [图片]Comments: This native plant, along with other members of the genus, is often undervalued because it is considered too common, and the flowers are not thought to be sufficient large and pretty. In fact, Pennsylvania Smartweed is rather attractive when the flowers are bright pink, and its ecological value to birds, moths, butterflies, and other insects, regardless of the color of the flowers, is quite high. Different varieties of this smartweed have been described by some authors (e.g., Mohlenbrock, 2002); Persicaria pensylvanica laevigata is the most common variety in Illinois, which is distinguished from the others by the glabrous lower surface of its leaves. Distinguishing Pennsylvania Smartweed from other smartweed species (Persicaria spp.) can be difficult, in part because of its variability across different populations of plants. This variability includes such features as the color of flowers (white, light pink, rosy pink), the hairiness of the foliage, and the width of the leaves. Pennsylvania Smartweed has the following features that are sometimes helpful in making a correct identification as to species: 1) the ochrea on its stems lack bristles along their upper rims, 2) the peduncles of its inflorescences are usually glandular pubescent, 3) its spike-like racemes are usually straight and more or less erect, rather than curved and nodding, 4) it usually forms taller plants than most smartweed species and its leaves are more long and wide, and 5) its flattened seeds are usually larger in size. Other common names for this smartweed are 'Pinkweed' and 'Big-seeded Smartweed.' Another scientific name of this plant is Polygonum pensylvanicum laevigatum.

Description: This herbaceous perennial plant is 2-3½' tall, branching sparingly. The slender stems are round and hairless. The alternate compound leaves occur sparingly along the stems; they are doubly pinnate, and about 8" long and half as wide. The slender leaflets are up to 1/8" (3 mm.) across. They often have 1-3 lobes, but their margins are smooth. The upper stems terminate in compound umbels with small white flowers. A typical umbel is about 6" across and has about 12 umbellets; these umbellets are loosely arranged, rather than compressed together. An umbellet is about 1" across and has 7-21 flowers. Each flower is about 1/8" (3 mm.) across, with 5 white petals that are notched in the middle, and 5 green sepals that are small and triangular. There are also up to 5 white stamens with 5 white anthers that are potentially observable; frequently, there appears to be fewer than 5 of these reproductive structures because they are fragile and short-lived. The blooming period occurs during early summer and lasts about 2 weeks. There is no noticeable floral scent. The root system is tuberous, which enables this plant to develop quickly during the spring and early summer. After blooming, it quickly fades away and becomes dormant for the rest of the year. Cultivation: The preference is light shade to full sun, and moist to slightly dry conditions. Wild Dill often grows in soil that is rich and loamy; it also tolerates some clay or rocky material. This plant should be cultivated more often in wildflower gardens. [图片]Range & Habitat: The native Wild Dill occurs occasionally in NE and central Illinois, but it is rare or absent elsewhere (see Distribution Map). Habitats include mesic black soil prairies, openings or edges near woodlands, areas along woodland paths, thickets, limestone glades, and bluffs. It often grows in grassy areas, but is easy to overlook, except during the short blooming period. This plant is more typical of high quality habitats than disturbed areas. Faunal Associations: The nectar of the flowers attracts many small bees, wasps, flies, and beetles. Among the flies, are such visitors as biting midges, Syrphid flies, thick-headed flies, Tachinid flies, flesh flies, bottle flies, Muscid flies, Chloropid flies, and others. Among the wasps, are such unusual visitors as cuckoo wasps and various parasitoid wasps, including the Chalcid, Perilampid, Eucoilid, Figitid, and Ichneumonid wasps. Little is known about this plant's relationship to mammalian herbivores; because the foliage is not known to be toxic, it is probably consumed by them occasionally. [图片]Photographic Location: The photographs were taken at Meadowbrook Park in Urbana, Illinois, and at Prospect Cemetery Prairie in Ford County, Illinois. Comments: This is an ethereal plant that is lovely while in bloom; unfortunately, this doesn't last very long. From a distance, Wild Dill may appear to be an early blooming Daucus carota (Wild Carrot), but closer inspection of the foliage and flowers will reveal significant differences between these two plants. What sets Wild Dill apart from many other white-flowered members of the Carrot family is the season of bloom (early summer) and the slender, delicate leaves (not wider than 1/8" across). Also, it should not be confused with Anethum graveolens (Cultivated Dill); this familiar annual herb from the Old World has yellow flowers. Another common name for Perideridia americana is 'Thicket Parsley.'

Description: This perennial plant is 2-3' tall, forming one or more unbranched flowering stalks. The central stem is light green, glabrous, and terete. Pairs of opposite leaves develop along the lower half of this stem; they are up to 5" long and 2" across, deltate-ovate to oblong-lanceolate in shape, and smooth to slightly toothed along their margins. Between the leaves on the lower stem and the inflorescence, the central stem is usually naked; sometimes pairs of small narrow leaves (1" long or less) can be found along the upper stem that resemble bracts. The upper surface of the leaves is medium to dark green and glabrous, while the lower surface is pale green and glabrous. Two Plants in Bloom The inflorescence consists of a cylindrical panicle of flowers about ½-1½' in length. Within this inflorescence, the flowers are clustered together at intervals in pseudo-whorls (about 6-12 flowers per pseudo-whorl). Individual flowers are about ¾-1" long and across, consisting of a funnel-shaped white corolla that flares outward into 5 rounded lobes, a small green calyx with 5 ovate teeth, 5 stamens (one of them sterile), and a pistil with a single style. Tiny glandular hairs occur along the outside and inside of the corolla. The peduncles and pedicels of the flowers are either glabrous or glandular-hairy. The blooming period occurs from late spring to early summer and lasts about 3 weeks. The flowers are replaced by ovoid seed capsules about 1/3" long; the latter eventually split open to release numerous small seeds. The root system consists of a crown with fibrous roots. Low basal leaves are usually present during winter dormancy. Cultivation: The preference is full or partial sun, mesic to dry conditions, and loamy or rocky soil. Well-drained conditions are required to prevent root rot. [图片]Range & Habitat: Trumpet Penstemon is uncommon in southern Illinois, and rare or absent in the rest of the state (see Distribution Map). Illinois lies near the northeast range-limit of this species. Habitats include meadows and openings in upland woodlands, oak savannas, thinly wooded bluffs, prairies, limestone glades, and prairie remnants along railroads. Faunal Associations: The nectar and pollen of the flowers attract long-tongued bees primarily: bumblebees, Anthophorine bees (Anthophora spp.), a Mason bee (Osmia distincta), and a wasp (Pseudomasaris occidentalis). The last two insects are oligoleges of Penstemon spp. (Penstemons). Other floral visitors include Green Metallic bees (collect pollen only) Swallowtail butterflies (suck nectar only), and the Ruby-Throated Hummingbird (suck nectar only). Moth caterpillars that feed on Penstemons include Elaphria chalcedonia (Chalcedony Midget), Oncocnemis saudersiana (Saunder's Oncocnemis), and Pyrrhia exprimens (Purple-Lined Sallow). Mammalian herbivores apparently make little use of the foliage as a food source. [图片]Photographic Location: A prairie in Fayette County, Illinois. The photographs were taken by Keith & Patty Horn (Copyright © 2010). Comments: Trumpet Penstemon is an elegant wildflower with an unusually long and slender inflorescence. In addition to these characteristics of its inflorescence, it differs from other Penstemon spp. (Penstemons) by the shape of its flowers (narrow and funnel-shaped at the base, rather than swollen), the large size and similarity of its corolla lobes, the lack of conspicuous leaves between the inflorescence and the leaves of the lower stem, the presence of tiny glandular hairs within its corolla, and the lack of hairs on its leaves and central stalk. Sometimes the scientific name of this species is spelled Penstemon tubiflorus (see Britton & Brown, 1913/1970).

[图片]一．冬季的土壤要求： 土壤的安排是，最好是给它提供排水性好、透气性好的，还要偏酸性的泥土。 二．温度安排： 因为这种植物喜欢温度高湿度也高，所以冬季因为天气寒冷的原因，而且它已经进入了休眠期，这个时候就需要把它的成长的环境的温度控制在15℃左右，如果温度低过10℃，它的叶子就会开始变黄发干，而且很容易会掉落。 [图片]三．光照： 这种植物喜欢阴性的地方，不能接受被阳光直射暴晒，但是可以把它放在有散光并且通风的阴性的地方，冬季的休眠期可以给它安排一个干燥阴凉的地方，这样可以促使它的花芽的分化，但是在它冬季开花之前如果适当地给它增加光照，它的开花质量就会相对地提高。 四．水分控制： 这种植物本身的生长就需要非常多的水分，但是在冬天有一个短暂的休眠期，可以给它少浇水，只要保持盆里的泥土稍微干燥就好，等到了冬天的开花期，这个时候就需要给它补给它所需要的水分，盆里的泥土也要对应地维持湿度，而且一定要给它提高空气的湿度。 [图片]五．肥料控制： 它在冬季有一个开花期，这期间可以适当地给它增添磷钾肥，来补充它开花所需要的大量的养分。 六．养护注意事项： 1、土质必须要疏松，绝对不能含有石灰质，如果含有石灰质，土壤会偏碱性，对于它的成长不利。 2、当它在要开花的时候绝对不可以施加肥料，肥料的施加时间可以安排在开花之前还有花谢后。

金鸡菊一般做绿化植物用，有网友问及金鸡菊什么时候播种，在全国大部分地区都可以在春季播种，也就是3-4月份的时候播种，北方可根据实际情况适当延后。 [图片]春季播种的金鸡菊大概在5-6月份左右就能开始开花了，花期可以一直持续到10月份左右，金鸡菊花期比较长。 如果是小范围种植，比如盆栽之类，播种期就相对自由一些了，8月份也可以播种。 [图片]金鸡菊为多年生宿根草本，而且可以自行繁衍，所以一般撒播一次后，第二年可自行发芽。 金鸡菊类耐寒耐旱，对土壤要求不严，喜光，但耐半阴，适应性强，对二氧化硫有较强的抗性。

[图片]一、浇水引起的 1.水分过多 有的时候，我们为了想要它赶快长大，所以就会不停的去浇水，这样子就会容易让水量太多，再加上它又非常喜欢干燥的地方，所以水量太多更不行。如果水量很多的话，就会让它的根长时间处在较湿的条件，进而让根容易烂掉，这样子就没办法吸收营养了，所以就会让它变得干枯。 2.水分太少 虽然它比较喜欢干旱的地方，但是也不能让水分太少了，如果水分过少，就会影响根的吸收效果。如果缺水时间太长了，就会让整个植株因为脱水开始干枯，所以也不能让水量太少了。 [图片]二、肥料引起的 1.肥量太多 如果给它施肥过勤或肥浓度太高的话，就会给它带来肥害，会对它的根和叶子造成伤害，中断营养传送，进而让营养跟不上，造成下面的干枯。所以一定要控制好施肥的量，才能让植株更好生长。 2.肥量过少 有时候肥料不够或者施肥浓度太低的话，也是会让它下面干枯的。所以这时候就需要我们给它增施一点肥料，在施的时候还要注意，对于这种长时间缺肥的植株，一定不能用浓度太高的肥料，防止烧根。 [图片]三、光照引起的 1.光照太强 所谓的光照太强，也就是在夏天的时候，这时候光线比较强，如果它不小心受到了强光照射，就会容易把它的叶子灼伤，进而出现干枯的现象。所以在夏天光线较强的时候，我们需要把它及时的搬回房间，防止它受到强光照射。 2.光线太弱 钱串，除了在夏天不能受到强光照射，其它的时候，都是可以尽情享受光照的。因为本身它也比较喜欢阳光。如果光线太弱的话，就会让它的下面干枯。 [图片]

[图片]一．原因分析 1.给水次数及水量过多。因为给水过多，造成新叶泛黄，但老叶子没有什么明显的变化。 2.缺水。有水量过多的情况不可避免地也会有缺水的情况，因水不够会引起下面的老叶子黄掉，时间长了会整株叶子黄掉从而干枯死掉。 3.肥料过多。肥料放置过多会使新叶子表面坑坑洼洼生长不平。 4.缺肥料。不按时施肥会让植株缺少营养，新叶子和嫩茎会黄掉，时间长了会使植株死掉。 5.植株缺铁。室内种植会让土壤不稳定，会随时变化，会使叶子呈现不同程度的干瘪黄掉。 [图片]二．解决办法 1.浇水问题：要按时浇水，控制浇水量和浇水的次数来避免浇水过多或植株缺水引起的植株叶子干瘪。 2.肥料问题：要按时按量进行进行追肥，避免一次性肥料过多让植株发育畸形或长时间不施肥让植株缺失营养而引起的叶子泛黄的情况。 3植株缺铁问题：按比例用7份饼肥和5份硫酸亚铁一起和水配成稀释液浇到植株上，可解决这个问题。 总结：要在养护上多加细心，充分了解其习性以及生长环境，既要保持盆栽内的水分又要适当地给予阳光照射，并要在高温时注意给它通风遮挡阳光。此外还要定期修剪植株，给盆栽内的土进行松土透气等。 [图片]

[图片]1.适当的光照 钱串是非常喜欢阳光的，它在光照充足的条件下生长速度会很快，所以在大多数的情况下，我们应把它放在光照较多的地方，让它尽情的享受光照。 但是并不是任何时候，都这么的随心所欲，当到了夏天的时候，尤其阳光过强时，千万不能让它此时去晒太阳，不然就会晒伤它的叶片，从而影响它生长。我们这时候可以把它搬回房间，或者也可以在外面搭一个小棚子来遮荫。 [图片]2.适合的土壤 虽然它本身对土壤的要求并不是很高，但最起码要保证透气疏松，而且排水能力也要好，因为它是非常害怕积水的。另外，一般在选择土壤的时候，我们可以人为的配置一下，只要满足以上要求就可以让它长的更快。 3.合理的浇水 它喜欢干燥的地方，极讨厌一些比较潮湿和闷热的环境。所以我们在平时打理的时候，一定要处理好浇水的水量和频率。尤其是在夏天和它的生长季节时，浇水要更小心一点，一般都是等到盆土干了再去浇，不干的话就无须去浇。另外在冬天的时候，浇水也是要小心一点的，一般都是超过10℃的话，再进行正常浇水，如果低于这个温度，就要停止浇水。 [图片]4.适当的施肥 为了让它长得更快，这期间养分是一定要给够的，尤其是在生长期的时候，需求更大，基本上每半个月就要给它施加一次肥料。然后到了冬天的时候，跟浇水是同样的原理，如果温度大于10℃，就可以施肥，反之，则要停止施肥。 5.适当的修剪 因为在它生长时，容易长出很多分枝，从而会让营养扩散，不能让它正常生长。所以一定要进行适当的修剪，这样不但保证了营养的充足，让它长得更快，还可以让它的外观更加好看。

[图片]一、施肥的时间 众所周知，在每年九月到次年4到5月的这段时间，就是它的生长期，这时候肯定需要的肥量是很多的，所以这时候我们在施肥的时候，可以适当的多给它施加一点，从而给它提供充足的营养，让它更好的生长。 但是等过了中秋之后，这时候温度慢慢降了下来，如果要施肥的话就不能那么随心所欲了，我们为了让它能够平安的迎接冬天并顺利越冬，就必须要停止施加任何肥料了，以防给它带来肥。因为这时候温度很低，施肥太多会容易伤到它的根。 然后等到了春天就可以正常施肥了，另外到了夏天也要注意，尤其是高温时，施肥也是要适当减少的，以防高温给根带来伤害。 [图片]二、肥料的选择 在刚开始栽培它的时候，我们应该在基质中加入一些复合肥，以满足它前期所需，然后等到了生长期之后，每个月可以给它施加一次稀薄的液态肥料。接着等到了秋天之后，就可以追施一点磷酸二氢钾，浓度要掌握好，就这样施加个2到3次，便可以让它叶片更加硬化和充实。 之后在每年给钱串换盆的时候，我们可以在它的盆底加入一下长效基肥，这样就可以长时间的给它提供营养。 然后在平时养护时，还需施加少量的复合肥，这种肥料的肥效非常快，使用也很方便，而且在施加之后会让养分更多，但是要注意的是，施加的量要合理一点。 [图片]三、其他的注意事项 在平时施肥的时候，一定要注意不能让肥料撒到叶子上面，或者直接埋到根上，不然就会让叶子黄化、根系腐烂，严重的时候还会让整个植株死掉。 所以在施肥时，一旦发现肥料撒在叶子上，就要及时的给它抖落掉，或者是擦掉，对于根也是，在施肥时，尽可能让肥料离根远一点。 [图片]

[图片]一、生长期的浇水 很多多肉植物在生长期的时候，需要的水量是很大的，钱串当然也不例外。在每年9月到下年的4到5月，这一段时间就是它长得最旺盛的时期，所以我们一定要满足它对水分的要求，但是在冬天温度特别低的时候要控制给水量，例如当温度低于10度的话，即使是在生长期，也要节制浇水，除非温度保持在10度以上就可以正常浇水。所以生长期浇水也是要看天气情况的。 二、根据种植环境浇水 在对它浇水的时候，也是看要下你的种植环境，如果你是在北方的话，因为天气非常的干燥，所以浇水可以稍微勤一点，量也可以适当的多一点。但如果你是在南方的话，那就要控制一下浇水了，因为南方的天气是非常湿润的，不像北方那么干燥，所以需要的水量并不是非常多，那我们浇水的次数就可以适当的减少。 [图片]三、根据植株的种植时间浇水 1.刚种的植株 浇水也是要看下你种的钱串时间长短来决定。如果它是刚刚被种上的，那就不能给它浇水，也不能晒太阳，一般要等个10天到2周以后，才能去给它浇水，因为刚种的钱串根系还是处于受损状态，这时候它基本上已经停止生长了，它的根吸收水分也是极少的，所以这时候对于水分的需要是很少的，如果你这时非要去浇水，就会容易造成积水，让根长时间处在较湿润的状态，从而导致烂根，所以一定要等到它的根已经长好了再去浇水。 2.种植时间较长的植株 如果它是已经种植时间很长的植株，那我们只需要正常浇水就可以了，因为这时候它的植株已经足够健壮了，对于水分的需求也要比刚种的植株大一点。
