银皇后别称银皇后万年青、银后粗肋草、银后亮丝草等，为天南星科广东万年青属多年生草本植物，叶色美丽，特别耐阴，有独特的空气净化能力，在厅室点缀盆栽会感到明亮舒适，目前其剪叶插花休闲或装饰室外环境已属时尚。
银皇后叶子发黄的原因 浇水过多 浇水过多，造成土壤板结或者粘性过重，使得银皇后的根部呼吸不畅，造成根须腐烂，使得根系吸收水分和养分的能力降低，严重影响植株的生长，造成植株的叶尖萎蔫发黄。 空气干燥、光照过强、温度过高 这三种情形通常出现在夏秋季节，，因为银皇后喜欢生长在空气湿润的半阴环境中，一旦空气干燥，阳光强烈，温度又刚好在30℃以上，很容易造成银皇后叶尖干枯。如果遇到这种情况，要立即将银皇后移到半阴环境，将枯叶剪掉，并且经常喷水、通风，新生长的银皇后的叶子会恢复正常。 长期不换盆 长时间不换盆，盆底土壤板结，根系生长空间不充裕，在高温高旱的环境下，很容易造成银皇后根系先端枯萎，使其丧失吸收功能。若遇到这种情况，可以将银皇后从花盆中倒出，将枯死的枝叶剪掉，将坏死的根系剪掉，换上一半的新土，然后放在凉爽、湿润、半阴的环境中，注意及时喷水。 银皇后叶子发黄怎么办 控制浇水 银皇后入室后，空间不如室外的开阔，盆土及植株表面的水分都会有所降低，所以浇水要适当的减少，若此时还照常浇水，很容易造成植株烂根，叶子发黄。所以银皇后浇水要注意浇水量，有规律的进行，盆土快干时浇水，浇水就要浇透。 调整光照 银皇后喜欢半阴的环境，很耐阴，不要担心长期遮阴也会影响它的生长。只要你的家中不是漆黑一片，放在家里的任何一个角落，它都会生长的很好，不需要特意的补充阳光。 减少施肥 入秋后，银皇后的生长会逐渐变缓，对养分的吸收能力也逐渐降低，此时需要减少施肥，以防止银皇后叶子发黄。施肥时尽量选用液肥，薄肥勤施。 保持适温 银皇后喜欢温暖的生活环境，当温度低于10℃时就会停止生长，当低于5℃时会影响银皇后的生长，造成叶子发黄。同时养护过程中，尽量控制温度恒定，不要忽忽低。

鸢尾花为蓝紫色，花形似翩翩起舞的蝴蝶。五月，鸢尾花开的季节，你就可以看见一 只只蓝色蝴蝶飞舞于绿叶之间，仿佛要将春的消息传到远方去。法国人视鸢尾花为国花。因为相传法兰西王国第一个王朝的国王克洛维在受洗礼时，上帝送给他一件礼物，就是鸢尾。在法国，鸢尾是光明和自由的象征。
鸢尾叶子发黄的原因：阳光过度照射 鸢尾喜欢半阴的环境，这也是大部分鸢尾在温室培植的原因。在室外培植要注意遮蔽阳光，过度光照叶子会发黄。尤其是夏季正午，烈日炎炎，盛开的鸢尾在阳光照射下，水分蒸发较快，叶片易被灼伤，造成植株枯黄。 解决方法：阳光较强时，进行遮阴。另外室外养殖鸢尾，正午可适当进行喷雾，增加空气湿度降温。 鸢尾叶子发黄的原因：浇水过量 鸢尾不喜欢太潮湿的环境，所以最好不要过度频繁的浇水。盆土积水，根部呼吸受限，造成叶片变黄。 解决办法：成长期间7天浇一次水，温度降低水量要慢慢较少，盆土稍微干燥即可。 鸢尾叶子发黄的原因：浇水过少 随说鸢尾不需要太多的水分，毕竟是植物嘛，所以适量的水分也是必不可少的。盆土太过干燥是不利于它成长的，从而造成叶子泛黄。 解决方法：成长的时候需要适量的水分。 鸢尾叶子发黄的原因：肥料过量 许多花友在养护过程中，对鸢尾所需肥料及施肥时间不是很明确，施肥过多，造成土壤板结，影响根系生长，导致叶黄。 解决办法：培植前用些基肥，每年秋天施肥料一次，成长期可适量增加。

Description: This herbaceous perennial plant is ½–3' tall, producing one or more stems that are unbranched, except at their apices, where the inflorescences occur. Each stem is light green, terete, glabrous, and sometimes glaucous (rarely it is pubescent). Alternate leaves occur along the entire length of each stem, except at the apex underneath an inflorescence, where the uppermost leaves occur in a whorl of 3 or more. They are widely spreading to ascending. Individual leaves are up to 2½" long and ½" across; they are linear-oblong to oblong in shape and their margins are entire (toothless). The tips of these leaves are blunt, while their bases are sessile or nearly so. The upper and lower leaf surfaces are light gray-green to medium green and glabrous (rarely the lower leaf surface is pubescent). Leaf venation is pinnate with prominent central veins. The foliage of this plant contains a toxic white latex. Each mature stem terminates in a panicle of flowers up to ¾' long and 1' across. This panicle is somewhat flat-headed and it has an open airy appearance. Individual flowers span about ¼" across (including their petaloid bracts). Each flower has a tiny cup-like cyathium containing the reproductive organs, 5 white petaloid bracts, and 5 green glandular appendages at the bases of these bracts. Because Flowering Spurge is monoecious, separate male (staminate) and female (pistillate) flowers are produced on the same plant. Each male flower has several stamens, while each female flower has an ovary with a tripartite style. The petaloid bracts are obovate in shape; sometimes they are slightly notched at their tips. The branches and pedicels of the inflorescence are light green, glabrous, and terete; pairs of small leafy bracts up to ½" long occur at the bases of pedicels and where the branches divide. The blooming period occurs from early summer to early autumn, lasting about 1-2 months for a colony of plants. There is no floral fragrance. During this time, an entire plant may lean to one side because of the weight of its inflorescence. Afterwards, the female flowers are replaced by 3-celled capsules of seeds that are 3-4 mm. long, globoid, and 3-lobed in shape; there is one seed for each cell of a capsule. At maturity, these capsules split open to eject their seeds. The seeds are 2-3 mm. long, ovoid-obovoid in shape, and finely mottled. The root system consists of a taproot that becomes woody with age.
Cultivation: The preference is full sun and mesic to dry conditions. This plant will tolerate almost any kind of soil, including those that contain loam, clay, sand, gravel, or rocky material. Poor soil is actually preferred because of the reduction in competition from other plants. Drought resistance is excellent and disease is rarely a problem when the soil is well-drained. Range & Habitat: The native Flowering Spurge occurs in every county of Illinois (see Distribution Map), where it is common. Habitats include black soil prairies, clay prairies, sand prairies, gravel prairies, dolomite prairies, various kinds of hill prairies, openings in rocky upland woodlands, opening in sandy upland woodlands, typical savannas and sandy savannas, thinly wooded bluffs, limestone glades, stabilized sand dunes, roadsides, areas along railroads, mined land, and agricultural land in various stages of abandonment or neglect. Flowering Spurge can be found in either disturbed areas or high quality natural areas. Faunal Associations: The pollen and nectar of the flowers attract Halictid bees, masked bees (Hylaeus spp.), Crabronid wasps (Oxybelus spp. & others), paper wasps (Polistes spp.), the Five-banded Tiphiid Wasp (Myzinum quinquecinctum), Sphecid wasps, cuckoo wasps (Chrysididae), Syrphid flies, bee flies (Exoprosopa spp. & others), Tachinid flies, flesh flies (Sarcophagidae), Muscid flies, and small butterflies, including the endangered Karner Blue (Lycaeides melissa samulelis); see Robertson (1929) and others. Other insects feed on the sap, foliage, and other parts of Flowering Spurge. These species include the Euphorbia Bug (Chariesterus antennator), a flea beetle (Glyptina bicolor), and a monophagous aphid (Aphis pulchella); see Vestal (1913), Clark et al. (2004), and Hottes & Frison (1931). The polyphagous Potato Aphid (Macrosiphum euphorbiae) also feeds on spurges (Euphorbia spp.). The seeds are an attractive source of food to some birds, including the Wild Turkey, Greater Prairie Chicken, Bobwhite Quail, Mourning Dove, and Horned Lark (Martin et al., 1951/1961). Flowering Spurge is rarely eaten by mammalian herbivores because of the toxic white latex in its foliage. Photographic Location: A remnant prairie along an abandoned railroad in Urbana, Illinois. Comments: The typical variety of Flowering Spurge (Euphorbia corollata) has glabrous foliage, but there is an uncommon variety of this plant (var. mollis) with pubescent stems and pubescent leaf undersides. While the foliage is normally some shade of green, during the autumn it often becomes an attractive reddish color. For a species of the Spurge family (Euphorbiaceae), Flowering Spurge is more showy than most because of its relatively large inflorescence and the white petaloid bracts of its flowers. The flowers of most spurges in Illinois, whether native or naturalized, have either green to yellowish green floral bracts, or their floral bracts are tiny and easily overlooked.

Description: This herbaceous perennial plant is 3-6' tall. It is largely unbranched below, but forms occasional side stems toward the apex. The stems have indistinct lines of white hairs, and are generally pubescent. The leaves are primarily opposite, although the upper leaves near the inflorescence sometimes alternate. These leaves are up to 7" long and 2½" across, with petioles up to 1" long. They are lanceolate, largely hairless, with coarse serration along the margins, and there are 5 veins that diverge from the base. These leaves tend to nod downward from their petioles, and are often dark green. Inflorescence & Moths The flat-topped inflorescence consists of numerous heads of white disk florets; there are no ray florets. Each flowerhead has about 12 disk florets. Each disk floret is about ¼" long, narrow and tubular, with 5 small triangular lobes at the top. There is also a long divided style that is white, which protrudes conspicuously from each floret. The blooming period occurs during late summer or early fall and lasts about a month. There is occasionally a mild floral scent. The small achenes develop flat tufts of hair and are dispersed by the wind. The root system is fibrous and rhizomatous. This plant often forms colonies by means of these rhizomes. Cultivation: The preference is partial or full sun and moist conditions. The soil should be loamy and high in organic matter. Lower leaves sometimes discolor and fall off during a drought, otherwise this plant is subject to few problems. The size of this plant is significantly affected by moisture levels.
Range & Habitat: The native Late Boneset occurs in nearly all counties of Illinois, except for possibly three counties in the north (see Distribution Map). This is a common plant. Habitats include moist black soil prairies, moist meadows near rivers, swamps, areas near drainage ditches, low-lying areas along railroads and roadsides, pastures, and abandoned fields. This plant is often near sources of water, or where the water table is not far below the land surface. It is more common in disturbed areas. Faunal Associations: The flowers are very popular with many kinds of insects, including long-tongued bees, short-tongued bees, wasps, flies, small to medium-sized butterflies, skippers, moths, and beetles. Most of these insects seek nectar, although bees may collect pollen and beetles may feed on it. In the upper photograph, are two Ailanthus Webworm Moths sucking nectar from the flowers. The caterpillars of various moths can be found feeding on various parts of this and other Bonesets, including Haploa clymene (Clymene Moth; eats foliage), Phragmatobia lineata (Lined Ruby Tiger Moth; eats foliage), Carmenta bassiformis (Eupatorium Borer Moth; bores into roots), Schinia trifascia (Three-Lined Flower Moth; eats flowers and seed capsules). Mammalian herbivores rarely consume this plant because of the bitter foliage. In overgrazed pastures, Late Boneset often becomes more common because of reduced competition from other plants. Photographic Location: The photographs were taken along a drainage ditch in Judge Webber Park in Urbana, Illinois. Comments: The delicate flowers of Late Boneset closely resemble the flowers of other Bonesets, such as Eupatorium altissimum (Tall Boneset) and Eupatorium perfoliatum (Common Boneset), in both color and structure. These Bonesets can be distinguished readily from each other by an examination and comparison of their leaves. Tall Boneset has leaves that are pubescent, more narrow, and less coarsely serrated than Late Boneset, while Common Boneset has leaves that wrap around the stem and are without petioles.

Description: This perennial plant is 2-4' tall and unbranched, except for some flowering side stems near the apex. The central stem and side stems are covered with long white hairs. The opposite leaves are up to 8" long and 2" across, and light or yellowish green. Their bases surround the central stem and merge together (perfoliate). In shape, they are lanceolate with long narrow tips and serrate margins. There is a conspicuous network of veins, particularly on the lower leaf surface. This lower surface is also pubescent. Some of the upper leaves near the inflorescence(s) are much smaller in size and sessile. The upper stems terminate in clusters of white flowerheads, spanning about 2-8" across. Each flowerhead is about 1/6" (4 mm.) across and consists of about 15 disk florets. Each disk floret has 5 spreading lobes and a long divided style, in the manner of other Eupatorium spp. The blooming period is late summer to early fall, which typically lasts about 1-2 months for a colony of plants. There is a pleasant floral scent. The florets are replaced by achenes with small tufts of hair – they are dispersed by the wind. The root system is fibrous and produces rhizomes in abundance. Common Boneset typically forms vegetative colonies. Cultivation: The preference is full or partial sun, and wet to moist conditions. The soil should contain considerable organic material so that it can retain moisture. This plant can withstand flooded conditions for short periods of time, but it is not really aquatic. The foliage appears to be little bothered by pests and disease. Range & Habitat: The native Common Boneset has been reported from most counties of Illinois, and it is fairly common (see Distribution Map). However, this plant appears to be somewhat less common than either Eupatorium serotinum (Late Boneset) and Eupatorium altissimum (Tall Boneset). Habitats include openings in floodplain forests, poorly drained areas of black soil prairies, and various kinds of wetlands, including marshes, bogs, fens, seeps, edges of rivers, and sand flats along Lake Michigan. This plant also occurs in or near roadside ditches. Generally, it doesn't stray far from wetland areas of one kind or another.
Faunal Associations: The nectar or pollen of the flowers attracts many kinds of insects, including bees, flies, wasps, butterflies, and beetles. In particular, many kinds of unusual flies and wasps are attracted to the flowers because of the accessibility of the nectar. The caterpillars of various moth species are known to feed on various parts of Common Boneset, including Haploa clymene (Clymene Moth), Phragmatobia lineata (Lined Ruby Tiger Moth), Papaipema cataphracta (Burdock Borer Moth), Schinia trifascia (Three-Lined Flower Moth), Chlorochlamys chloroleucaria (Blackberry Looper Moth), and Semiothisa continuata (Geometrid Moth sp.). The small seeds appear to be of little interest to birds and other fauna, although they are occasionally eaten by the Swamp Sparrow. Mammalian herbivores display little interest in Common Boneset as a food source because of the bitterness of the foliage.
Photographic Location: The photographed plants were growing at the bottom of a drainage ditch amid horsetails near the Windsor Road Prairie in Champaign, Illinois. This portion of the drainage ditch does not have standing water during dry weather (i.e., a seasonal wetland). Comments: Common Boneset has interesting foliage and fragrant flowers. It tolerates flooded conditions better than many other Boneset species. It can be distinghished from these other species by the perfoliate leaves that surround the central stem. The other species have opposite leaves that are sessile or have distinct petioles. All of these species have spreading clusters of white flowers with a similar appearance. These flowers are quite popular with diverse kinds of insects.

Description: This perennial plant is 3-4' tall and unbranched, except for the upper flowering stems. The stems are covered with white hairs. The opposite leaves are up to 5" long and 1" across, occasionally with small teeth along the margins. They are usually dark green, lanceolate to narrowly ovate, and pubescent. There are three conspicuous veins that run along the length of each leaf. The rather flat inflorescence consists of numerous heads of small white flowers and their buds. These flowers are dull white and individually only 1/8" (3 mm.) across. There is little or no floral scent. The blooming period occurs from late summer to early fall, and lasts about 1-1½ months. The achenes develop small tufts of white or light brown hair; they are dispersed by the wind. This plant may spread vegetatively through rhizomes. Cultivation: The preference is full or partial sun, and mesic to dry conditions. The soil can contain significant amounts of loam, clay, or gravel; soil with a high pH is tolerated. Drought tolerance is good, although the plant may wilt. Tall Boneset is very easy to grow, and competes well against other plants. It is usually not affected by foliar disease. Range & Habitat: The native Tall Boneset occurs in most of Illinois, except some southern counties (see Distribution Map). It is a common plant. Habitats include mesic to slightly dry black soil prairies, clay prairies, gravel prairies, savannas, thickets, openings in upland forests, dry banks of lakes, limestone glades, pastures and abandoned fields, fence rows, vacant lots, and areas along railroads. This plant favors disturbed areas, where it may form large colonies.
Faunal Associations: The nectar of the flowers attracts many kinds of insects, including long-tongued bees, short-tongued bees, wasps, flies, small butterflies, skippers, beetles, and plant bugs. Among these, wasps and flies are particularly common visitors. The wasp visitors include Paper wasps, Thread-Waisted wasps, bee wolves (Philanthus spp.), Scoliid wasps, Larrine wasps, Sand wasps, Spider wasps, and others. Fly visitors include Syrphid flies, bee flies, Tachinid flies, Muscid flies, and others. The caterpillars of several moths feed on various parts of Tall Boneset and closely related plants, including Haploa clymene (Clymene Moth), Phragmatobia lineata (Lined Ruby Tiger Moth), Carmenta bassiformis (Eupatorium Borer Moth; bores into roots), and Schinia trifascia (Three-Lined Flower Moth; eats flowers & seed capsules). Mammalian herbivores, including livestock, shun the bitter-tasting leaves of this plant; consequently, it tends to flourish in pastures.
Photographic Location: The photographs were taken at a flower garden along a sidewalk in Urbana, Illinois, and in a vacant lot near the same city. Comments: Tall Boneset often competes directly with Solidago canadensis (Canada Goldenrod) in disturbed areas, although it prefers slightly drier areas. The two plants appear similar to each other prior to bloom, although the former has darker leaves. This plant provides some white color to a fall landscape that is often dominated by forbs with yellow flowers and the brown color of dried-out grasses. This is the easiest boneset to grow in dry sunny areas. Some people may mistake this plant for a weed, which it is to some extent.

Description: This perennial plant is 2-5' tall. It has a stout central stem that is unbranched, except near the inflorescence. The alternate leaves tend to occur near the base of the plant, although a few smaller leaves occur along the upper portion of the stem. These leaves are long and strap-like, rather stiff in texture, and up to 2½' long and 2½" across. They are narrowly lanceolate, often curve downward, and have parallel venation. There are widely scattered, but stiff, teeth along the margins. The base of leaves clasp or wrap around the stalk. The entire plant is bluish or greyish green, and quite hairless. At the apex of the central stem, and sometimes from the axils of the upper leaves, occurs a long-stalked inflorescence. This consists of several prickly balls of flowers that are individually about ½–1" across. These whitish green balls contain numerous small white flowers that are individually surrounded by prickly bracts. A flower consists of 5 white petals, a divided white pistil, and several white stamens with light brown anthers. Each ball of flowers is subtended by a star-like rosette of small leaves. These flowers have a sickly honey-like scent in bright sunlight. The blooming period occurs from mid- to late summer, and the balls of flowers remain attractive for about 2 months. The root system consists of a central taproot. After blooming, a plant will gradually die down, but one or more offsets will develop at its base. Thus, a small clump of plants will eventually form. Cultivation: The preference is full sun and moist to slightly dry conditions. This plant becomes spindly in shadier conditions, and may topple over while in bloom. The soil can contain significant amounts of loam, sand, clay, or gravel, but the site should not be subject to standing water. This plant is easy to grow, and isn't bothered by foliar disease nor many insect pests.
Range & Habitat: The native Rattlesnake Master occurs in most of Illinois, except for some western and southern counties (see Distribution Map). It can be locally common in some high quality habitats, otherwise it is fairly uncommon. Habitats include moist to slightly dry black soil prairies, clay prairies, sand prairies, thickets, typical savannas, sandy savannas, and limestone glades. Faunal Associations: The flowering heads attract many kinds of insects, including long-tongued bees, short-tongued bees, wasps, flies, butterflies, skippers, moths, beetles, and plant bugs. These insects usually seek nectar, although some of the bees may collect pollen for their brood nests. The caterpillars of the rare Papaipema eryngii (Rattlesnake Master Borer Moth) bore into the stems and feed on the pith. The coarse foliage and prickly balls of flowers are not popular as a source of food with mammalian herbivores, although they may nibble off the ends of the leaves.
Photographic Location: The photographs were taken at the webmaster's wildflower garden in Urbana, Illinois. Comments: This is a very odd member of the Carrot family that resembles a yucca or some other desert plant. However, it is a true tallgrass prairie species with a unique appearance. A close relative is Eryngium leavenworthii (Leavenworth Eryngo), which is an annual plant with a purplish appearance. This latter species doesn't occur in Illinois, but can be found in dry prairies further west. In the past, the dried seedheads of Rattlesnake Master were used as rattles by Amerindians. Pioneers thought the roots could be used as an effective antidote to rattlesnake bite, hence the common name of this plant. However, this belief was erroneous.
