Description: This perennial vine is semi-woody and up to 30' long. Young stems are green, glabrous, and terete, while older stems are brownish green to brown. Opposite pairs of compound leaves occur at intervals along the stems. These compound leaves are odd-pinnate and they usually have 5 leaflets. The long petioles of these compound leaves can lean or bend around neighboring objects for support; tendrils are not present. This vine can climb small trees, fences, and similar objects; in more open areas, it sprawls across the ground. The leaflets are up to 3" long and 1½" across; they are ovate or ovate-cordate, glabrous, and smooth along their margins. The upper surface of each leaflet is medium green, while the lower surface is dull light green; its major veins are parallel. Each leaflet has a petiolule (or small stalk) at its base of varying length. From the axils of the upper leaves, there develops flat-headed panicles of flowers. The flowers are usually bisexual, although monoecious vines (with separate male and female flowers) may occur. Each bisexual flower has 4 petal-like white sepals (less often 5), many long stamens, and 5-6 pistils with elongated styles toward the center. Both the stamens and styles of the pistils are white or cream-colored. True petals are absent. The branches and branchlets of the panicle are green and slender. The blooming period occurs from late summer into fall, typically lasting about 1½ months. The flowers have a strong sweet fragrance. After the blooming period, each flower is replaced by a cluster of achenes with long spreading styles. These persistent styles are covered with long white hairs, which provides them with a feathery appearance. The large achenes are ovoid and flattened in shape; they are thinly covered with appressed silky hairs. Because of their feathery styles, the achenes are distributed to some extent by the wind. This perennial vine reproduces by reseeding itself. Cultivation: Autumn Clematis thrives in full sun to light shade, moist to slightly dry conditions, and a loam or clay-loam soil. It also tolerates gravelly soil and probably sandy soil as well. This vine can smother small shrubs and is rather aggressive; sometimes it even climbs up the trunk of trees to occupy the lower branches. [图片]Range & Habitat: Autumn Clematis has naturalized in widely scattered locations across Illinois (see Distribution Map). This vine is undoubtedly more common than official records indicate, and its abundance within the natural areas of the state is still growing. Habitats include edges of woodlands, thickets, fence rows, areas along railroads and roads, and waste land. Autumn Clematis is native to East Asia and it is often cultivated as an ornamental plant. This species can be considered somewhat invasive. Faunal Associations: The caterpillars of the moths Horisme intestinata (Brown Bark Carpet), Thyris maculata (Spotted Thyris), and Thyris sepulchralis (Mournful Thyris) feed on the foliage of Clematis spp. The caterpillars of the latter two species are leaf-rollers. There is a lack of information about floral insect visitors for Autumn Clematis, but they are probably similar to the visitors of the native Clematis virginiana (Virgin's Bower). The insect visitors of this latter species include Halictid bees, various kinds of wasps, and an abundance of flies. Most of these insects are seeking nectar from the flowers, although some of them may feed on the pollen or collect it. Because the foliage of Autumn Clematis is toxic, it is not eaten by mammalian herbivores. Photographic Location: Meadowbrook Park in Urbana, Illinois. [图片]Comments: Like the native Clematis virginiana (Virgin's Bower), Autumn Clematis has showy white flowers. The latter is often found in drier habitats than the former and it blooms later in the year. These two species of Clematis are easy to distinguish: Virgin's Bower has leaflets that are shallowly cleft and dentate, while the leaflet margins of Autumn Clematis are smooth (or nearly so). During the late summer or fall, when the achenes develop, it is also possible to distinguish these species according to their styles: Autumn Clematis has feathery styles, while the styles of Virgin's Bower are more smooth. Other Clematis spp. that occur in natural areas of Illinois have nodding purplish flowers with a very different appearance; they are called 'Leather Flower' vines. Because the leaflets of some Leather Flower vines have smooth margins, it is possible to confuse these species with Autumn Clematis when the flowers are not in bloom. Another scientific name of Autumn Clematis is Clematis dioscoreifolia.

Description: This plant is an obligatory biennial that forms a rosette of leaves during the first year, and bolts upward during the second year to produce flowers. It forms occasional side stems, but remains erect in stature, reaching 3-6' in height. The stout stems are light green, somewhat angular, and covered with dense white hairs. The alternate leaves are up to 7" long and 2" across. In outline, they are lanceolate in shape, but deeply pinnatifid. The widely spaced lobes narrow into points that are individually armed with a pale yellow spine. Some of the upper leaves near the flowerheads may be lanceolate or linear, but remain unlobed. Across the surface of the leaves, there are short white hairs and scattered small spines. The upper surface is dark green, while the lower surface is light green. At the base of each leaf, there are a pair of narrow wings that are dark green and decurrent against the stem. These wings are extensions of the leaves and arm the stems with spines up to ¼" long. The upper stems terminate in flowerheads of purplish pink to purple flowers. Each flowerhead is 1½–2" across and contains numerous disk florets, but no ray florets. Each disk floret is long and tubular, but becomes divided into 5 long thread-like lobes. This provides the flowerhead with a showy hair-like appearance. At the base of each flowerhead, are numerous green bracts that taper into stiff points that curl outward and are quite prickly. Among these bracts are cobwebby hairs in the background. The blooming period occurs from mid- to late summer and lasts about 3-4 weeks, after which the florets wither away. They are replaced by achenes with large tufts of white hair. These achenes are long, slender, and slightly ribbed. TheyDistribution Map are dispersed by the wind. The root system consists of a stout taproot that runs deep into the ground. This plants spreads by reseeding itself and occasionally forms colonies. Cultivation: This thistle usually grows in full sun under moist to dry conditions. It prefers a fertile soil that consists of loam, clay loam, or that is slightly stony. Occasionally the foliage is affected by mildew during the summer or fall. Individual plants can produce a great abundance of seed, which have a high germination and survival rate. Thus, this plant can be quite aggressive. Because the seeds remain viable for only 1-2 years, one control strategy consists of destroying individual plants before they reach the flowering stage. It is possible for a plant to reestablish itself if a portion of the taproot remains in the ground. Range & Habitat: The Bull Thistle is a common plant that occurs in most counties of Illinois. This thistle is adventive from Eurasia, and it has existed in the United States since the 19th century, if not earlier. Habitats include pastures, abandoned fields, fence rows, areas along roadsides and railroads, cut-over woods, and miscellaneous waste areas. This species prefers disturbed areas and it is not common in high quality natural areas. Faunal Associations: The nectar and pollen of the flowers attract many kinds of long-tongued bees, including bumblebees, leaf-cutting bees (Megachile spp.), long-horned bees (Melissodes spp.), and cuckoo bees (Epeolus spp.). The flower nectar also attracts butterflies (especially swallowtails), skippers, and bee flies. Green metallic bees and other Halictid bees may collect pollen from the flowers, but they are non-pollinating. The caterpillars of the butterfly Vanessa cardui (Painted Lady) feed on the foliage. There are also many moth species with caterpillars that consume various parts of thistles (see Moth Table). The seeds are eaten by the American Goldfinch and the Clay-colored Sparrow. Goldfinches also use the tufts of hair as construction material for their little nests. Mammalian herbivores don't eat the Bull Thistle because it is heavily armed with spines. Even in overgrazed pastures where cattle and sheep have little to eat, the Bull Thistle is one of the few plants that is left alone. Photographic Location: Along a fence row near the webmaster's apartment in Urbana, Illinois. [图片]Comments: This is a very spiny thistle that can become quite tall. It is easily distinguished from many of the native thistles by the prickly bracts at the base of the flowerheads. These large bracts curl outward and narrow into sharp points, while the bracts of native thistles are appressed together and resemble green fish scales (fine spines are usually present on the outer bracts for some native species). The leaf undersides of the Bull Thistle are light green or whitish green, while the leaf undersides for some native thistles, such as Cirsium discolor (Pasture Thistle) and Cirsium altissimum (Tall Thistle), are powdery white in appearance. Other native thistles, however, don't have this latter characteristic. The Bull Thistle also has spines on its stems (from the decurrent extensions of the leaves), while the stems of native thistles are spineless.

Description: This annual or biennial plant is usually 1½–3' high, branching occasionally. The stems are variously colored, ranging from green to reddish brown. The lower stems can be quite hairy, while the upper stems are nearly hairless. The alternate leaves are up to 8" long and 2" across, becoming smaller as they ascend the stems. They are lanceolate, elliptic, or oblanceolate in overall shape, and either pinnatifid or dentate; the upper leaves have margins that are more smooth (entire). Each leaf narrows gradually to a petiole-like base, where it is either sessile or clasps the stem. There are usually conspicuous hairs along the central vein of the lower leaf surface. The upper stems terminate in long inflorescences that are either spike-like, or they are open branching panicles. Widely spaced along the flowering stalks, there are sessile or nearly sessile flowerheads and short triangular bracts. These flowerheads are about 1-1½" across and they have 10-20 ray florets. The petaloid rays of these florets are light blue, fading to white; there are 5 tiny teeth at the tip of each petaloid ray. Toward the center of each flowerhead, there are several light blue stamens with blue anthers. The flowerheads bloom during the morning, and close-up later in the day, unless the skies are cloudy. The blooming period can occur from early summer to early fall, depending on the weather and the timing of disturbances (such as occasional mowing). The achenes are oblongoid and 5-ribbed; there is a pair of small scales at the apex of each achene. The root system consists of a stout taproot. Common Chicory spreads by reseeding itself. Cultivation: Common Chicory appears to prefer full sun and a heavy soil that contains clay or gravel. This plant is typically found in locations that are mesic to dry, and it withstands drought rather well. Road salt and alkaline conditions are tolerated better than most plants. The foliage can appear rather battered-looking by the end of a hot dry summer. [图片]Range & Habitat: The non-native Common Chicory has been reported in nearly all areas of Illinois, except a few counties in the NW and SE sections of the state (see Distribution Map). It is quite possible that Common Chicory occurs in those counties as well. This plant originated from Eurasia, and was present in Illinois by the late 19th century. It has been spreading steadily ever since and has become common, particularly in disturbed open areas. Typical habitats include pastures, abandoned fields, areas along roadsides and railroads, grassy areas that are not mowed regularly, undeveloped real estate lots, and other waste areas. Occasionally, Common Chicory colonizes disturbed areas of natural habitats (e.g., early stages of a prairie restoration), but it is not a serious invader of such natural areas in the long run. Faunal Associations: The flowers attract short-tongued bees and probably other insects. Both nectar and pollen are available as floral rewards. The foliage of Common Chicory is eaten by Melanoplus bivittatus (Two-Striped Grasshopper), Melanoplus femurrubrum (Red-Legged Grasshopper), and probably other grasshoppers. The larvae of a lizard beetle, Acropteroxys gracilis, bore through the stems of this plant, while the caterpillars of the moth, Pyrrhia exprimens (Purple-Lined Sallow), feed on the the flowers, buds, and developing achenes. Because the foliage contains a bitter white latex, it is probably not preferred as a food source by mammalian herbivores, although cattle and sheep reportedly eat the basal leaves. [图片]Photographic Location: Along a roadside in Urbana, Illinois. Comments: The roots of Common Chicory have been roasted to create a coffee-substitute; they are also used as an ingredient in some herbal teas. The flowerheads are very beautiful, but short-lived. This species is easy to identify because of the appearance of these flowerheads – they are a lovely light blue, whereas similar plants in the Aster family usually have yellow flowerheads. However, some Lactuca spp. (Wild Lettuce) have light blue flowerheads that are smaller in size. These latter species produce achenes with tufts of hair, whereas the achenes of Common Chicory have only small scales.

Description: This herbaceous plant is a summer annual. A typical plant is about 6" tall and 12" across; it is abundantly branched at the base, and occasionally branched above. The stems are ascending to sprawling, more or less terete, pale reddish green to reddish purple, and glabrous. Sometimes the stems have vertical stripes that are green alternating with red. Alternate leaves occur along the entire length of each stem; they are ¾–2" long and 6-15 mm. across. The leaves are elliptic-oblong, elliptic, broadly elliptic, or lanceolate; they are shallowly pinnatifid, coarsely dentate, and/or sinuate along their margins. The leaf bases are wedge-shaped, while their tips and lobes (if any) are blunt or acute. The upper leaf surface is medium green or bluish green and glabrous, while the lower leaf surface is white-mealy (farinose). The petioles are up to ½" long, light green to yellowish red, and glabrous. The stems eventually terminate in either spikes or panicles of interrupted clusters of flowers; there are also axillary spikes of flowers that develop from the upper leaves. Individual floral spikes are up to 2" long; there are several small flowers per cluster. Some flowers may have pedicels up to 0.5 mm. long. Each mature flower is about 2 mm. across, consisting of 3-5 greenish sepals, 3-5 stamens, and a pistil with a pair of styles; there are no petals. The sepals are lanceolate to ovate, bluntly tipped, and glabrous; they are either weakly keeled or flat. The stamens are exserted with yellow anthers. The rachises of floral spikes are glabrous. The blooming period occurs from early summer to early autumn. However, individual plants remain in bloom for about 1 month; only a few flowers bloom at the same time. The flowers are cross-pollinated by the wind. Afterwards, the ovaries of the flowers develop into seeds (a single seed per flower); the orientation of these seeds may be vertical or horizontal. The persistent sepals cover only the edges of these seeds. Individual seeds are 0.5–1 mm. across, globular-flattened in shape, and dark brown to dark reddish brown. Thin membranes cover the seeds; they are easily removed. The root system consists of a shallow taproot with secondary roots that are fibrous. This plant reproduces by reseeding itself. Cultivation: The preference is full to partial sun, more or less mesic conditions, and soil containing some sand or loose loam. The size of individual plants is variable, depending on soil fertility and moisture conditions. Once the seeds have germinated in late spring, growth and development is rapid. Range & Habitat: The adventive Oak-leaved Goosefoot is occasional in NE Illinois and uncommon elsewhere in the state (see Distribution Map). This plant is native to Eurasia. Habitats include cropland, gardens, construction sites, areas along railroads, roadsides, barnyards, and waste areas. Habitats with a history of disturbance are preferred, especially when this exposes the topsoil. [图片]Faunal Associations: Various insects feed on the foliage, roots, and other parts of goosefoot species (Chenopodium spp.). These insect feeders include the Three-spotted Flea Beetle (Disonycha triangularis), larvae of the Spinach Leafminer Fly (Pegomya hyoscyami), the Chenopodium Aphid (Hayhurstia atriplicis) and Sugar Beet Root Aphid (Pemphigus betae), the Chenopodium Leafhopper (Norvellina chenopodii), and the larvae of such moths as the Flamboyant Twirler Moth (Chrysoesthia lingulacella), Hollow-spotted Blepharomastix (Blepharomastix ranalis), Chenopodium Scythris Moth (Scythris limbella), Eight-Spot (Amyna octo), Ragweed Borer Moth (Epiblema strenuana), and Morning Glory Plume Moth (Emmelina monodactyla). In addition, the caterpillars of two skippers, the Common Sootywing (Pholisora catullus) and Hayhurst's Scallopwing (Staphylus hayhurstii), also feed on these plants. Among vertebrate animals, upland gamebirds and many songbirds, especially sparrows, eat the seeds of goosefoot species (Martin et al., 1951/1961). The Bird Table provides a list of these species. Some small rodents also eat the seeds, including the Thirteen-lined Ground Squirrel, Prairie Deer Mouse, and White-footed Mouse (Whitaker, 1966). White-tailed Deer browse on the foliage and seedheads of goosefoot species, including Oak-leaved Goosefoot. The seeds of these plants are able to pass through the digestive tract of this animal and remain viable. In this manner, the seeds are dispersed across considerable distances (Myers et al., 2004). [图片]Photographic Location: Along a sidewalk in Urbana, Illinois, where some construction and landscaping activity occurred. Comments: Oak-leaved Goosefoot (Chenopodium glaucum) can be distinguished from most goosefoot species (Chenopodium spp.) by the shape of its leaves. In addition, the undersides of its leaves are white-mealy, while the rest of the plant is glabrous or nearly so. The flowers of Oak-leaved Goosefoot are also glabrous, and their sepals cover only the margins of the developing ovaries or seeds. Other goosefoot species usually have differently shaped leaves, their flowers are more or less white-mealy, and their sepals cover most of the developing ovaries or seeds. Like other weedy goosefoot species, Oak-leaved Goosefoot has a preference for disturbed habitats with exposed topsoil. It is less erect than most of them, having a tendency to remain relatively low and sprawl across the ground. There is a variety of Oak-leaved Goosefoot, Chenopodium glaucum salinum, that is native to the western United States. It tends to have bluish foliage, while the lobes, teeth, and tips of its leaves are usually more narrow and pointed. There are no records of this variety occurring in Illinois at the present time.

为什么黄叶？ 1、光照太强。 吊兰是比较喜阴的花，不能接受太阳的强烈照射，如果有花友把它放在南阳台上养着，非常容易黄叶。 解决方法： 吊兰放在室内有散射光的地方养护就可以，比如客厅、卧室等等。不要给予过强的阳光照射。 2、肥料不够。 水培的吊兰不能像土培一样吸收更多的微量元素，所以不经常换水的话，很容易造成营养不足而导致黄叶。 解决方法： 吊兰主要施氮肥，可以用尿素和水按照1:800的比例混合施在瓶中，注意不要过量，否则容易烧根。 3、不及时修剪。 叶子太过茂密会加速营养的吸收，叶子就会变黄，另外，杂根太多会影响吊兰对营养的吸收，也会导致黄叶。 解决方法： 及时把黄叶剪掉，吊兰太过茂密可以进行“砍头”操作，保证其他叶子能正常生长，把多余的虚根修剪掉，使根部能够充分的吸收营养。 水培绿萝黄叶 绿萝 为什么黄叶？ 1、环境突变。 一般刚买的绿萝到家会有一个适应新环境的过程，这时候如果有黄叶是正常现象。只需及时剪掉黄叶即可。 解决方法： 可以把刚买回来的绿萝放在卧室里或者家里其他的有散射光的地方，慢慢等它服盆即可。 2、营养不足。 水中营养不如土中的多，营养不足也会导致绿萝叶片发黄。 解决方法： 绿萝也是观叶植物，主要施氮肥，除了尿素，我们可以用腐熟的大豆水稀释20倍之后加一点在水培瓶中，平时可以往叶片上喷喷水。 3、水质较差。 有的花友直接用家里的自来水养绿萝，没有经过别的处理，自来水里的氯气对绿萝的生长不利，容易导致黄叶。 解决方法： 要勤换水。水培瓶中的水加到瓶子的1/2左右就可以，每2个周换1次水，换的时候不用把根拿出来，直接沿着平边往里倒即可。 水培铜钱草黄叶 为什么黄叶？ 1、营养不足。铜钱草长得很快，所以水中的营养消耗也非常迅速，如果出现黄叶倒伏的现象，很可能是营养不足了。 解决方法： 半土半水养殖。这样可以同时满足铜钱草对水分和营养的需要，一举两得。先往瓶里加土到1/2，然后种上铜钱草，再加水，慢慢加，不要把铜钱草冲倒，之后水少了再加即可。 2、通风不良。即便是水培，铜钱草依然需要一个通风良好，不憋闷的环境，如果空气过于潮湿且不流通就很容易造成铜钱草叶片发黄发蔫。 解决方法： 注意摆放位置。把水培铜钱草放在阳光充足且通风的地方，比如南阳台。 水培富贵竹黄叶 为什么黄叶？ 1、施肥不当。刚买的富贵竹一般没有根，所以吸收养分的能力较差，容易黄叶；但是施肥过量也会导致富贵竹叶片变黄。 解决方法： 刚买回来的富贵竹可以把下端倾斜45°切一刀，增加吸收营养的面积，还能促进生根；如果施肥过量，要马上停止施肥，剪掉黄叶，重新换水，稀释肥料。 2、光照不当。光照不足，富贵竹不能进行充足的光合作用，叶片会不绿；光照过强，富贵竹不耐晒，叶片也会变黄。 解决方法： 富贵竹喜阴，对光照的要求不是太严格，平时就放在客厅即可。 3、不换水。水培绿植不能一直不换水，水中的氧气、营养在利用一段时间后都会减少，慢慢地就满足不了富贵竹需要的条件了。 解决方法： 水质变差，容易滋生细菌，影响富贵竹的呼吸，一般一个月换一次水，平时水少了就往瓶中加水即可。 水培龟背竹黄叶 为什么黄叶？ 1、养分缺失。水培时间长了，水中营养不足，就容易导致龟背竹黄叶。 解决方法： 龟背竹是比较大型的观叶植物，家里可以常备一些专用的营养液，每个月往水里加一两滴，叶子就能绿油油了。 2、温度过低。龟背竹也不耐寒，冬天温度过低，龟背竹受冻易黄叶。 解决方法： 冬天温度低的时候，要注意给龟背竹保暖，白天可以多接受光照，注意不能受冷风，否则容易冻伤。 3、通风不良。虽然龟背竹喜湿润，但如果空气长期不流通， 而导致环境又湿又闷，很容易把它的叶子闷黄。 解决方法： 把龟背竹放在家里通风的地方，时常在周围喷喷水，保持空气的清新。

Purple sage (Salvia leucophylla) is an evergreen plant that typically grows 3 to 6 feet tall, though some individual specimens have been known to reach 12 feet tall and 12 feet wide. Purple sage shrubs have aromatic gray-green vegetation, an attractive, airy form and fragrant lavender-pink blooms. They thrive in full sun but need no water once established, which makes them ideal for drought-tolerant landscaping. Plants also tolerate freezing temperatures. This distant relative of culinary sage is best pruned minimally, to support general plant health and encourage optimal flowering in the landscape. [图片]Step 1 Prune purple sage only with a purpose, because any unnecessary trimming will only diminish the amount of attractive, fragrant flowers. Step 2 Make major pruning cuts only when purple sage is dormant, near the end of the winter when the coldest temperatures have passed. Step 3 Assess the shrub and its condition thoroughly before making any additional pruning cuts. First cut off dead, diseased or otherwise damaged branches and stems. Step 4 Stand back to study the plant's symmetry and general proportions, walking all the way around if necessary. Make your next cuts to enhance overall balance. Step 5 Trim lightly to remove dead branches and stems -- or to make corrective cuts you may have missed earlier -- at any time during the year. [图片]Step 6 Deadhead spent purple sage flowers for a neater look if desired, but this isn't absolutely necessary because dried flowers look fine too -- and leaving them gives seeds a chance to develop and disperse.

The name golden moss fern is deceptive as this plant is neither a moss nor a fern, but it does share characteristics of both. Like ferns and moss, this plant is non-flowering and produces spores as a primary means of reproduction. It grows just 6 inches tall with a spreading growth pattern that resembles a moss. Golden moss fern grows well as a ground cover in shady damp areas. It is also known by its scientific name, Selaginella kraussiana 'aurea,' or the common name gold clubmoss. [图片]Step 1 Plant golden moss fern in peat or humus-rich soil. A shady spot that naturally stays slightly damp most of the year is ideal. Avoid planting it in areas that experience periods of standing water or perpetually muddy conditions. Step 2 Dig a planting hole the same depth and 3 to 4 inches wider than the root mass. Slide the golden moss fern out of the nursery container and place it upright in the hole. Backfill the hole and smooth the soil under the golden moss fern. Step 3 Space multiple plants 6 to 12 inches apart. Individual golden moss fern plants reach a diameter of up to 2 feet when mature, but you may plant them closer together to get a ground cover started and then divide the plant later if they get too crowded. Step 4 Fertilize the plants twice a month. Use an all-purpose balanced fertilizer but dilute it to one-quarter the strength recommended on the package. Select a water-soluble or a slow-release formula. Discontinue fertilizing in the fall and resume in the spring. Step 5 Water the soil around golden moss ferns when it starts to feel dry on top. Soak the area around each plant down to 1 to 2 inches deep. [图片]Step 6 Divide golden moss fern in the spring. Dig up the entire root ball and pull it into sections of about 4 to 6 inches across. Replant the divisions in the garden or pot them for use as indoor plants. Replant the main root mass in the original spot.

Anthurium is a genus of tropical flowers native to the West Indies, Mexico and South America. They are commonly grown in warm climates such as Hawaii and southern Florida, as well as indoors and in greenhouses. They are noted for their large, colorful flowers and long spathes and are often used in bouquets and floral arrangements. Anthuriums can be propagated from seed and through division or cuttings. Division is the fastest method to propagate anthuriums and can be done by the average home gardener. [图片]Step 1 Examine the plant and look for offshoots that emerge from the ground near the main stem. The shoots grow from the roots of the main plant. In one year, up to 15 can appear from a healthy anthurium. Step 2 Dig up healthy-looking offshoots. Using sharp garden clippers, cut the roots about 4 to 5 inches deep to remove the offshoots from the mother plant. These aerial roots are necessary for successful propagation. [图片]Step 3 Replant the divided shoots in 4- to 6-inch pots that are filled with rich, organic potting soil. Keep the soil moist and place the pots in a humid location with partial sun.

Lamb's ear, known scientifically as Stachys byzantina, is a fuzzy plant with grayish-green leaves. It produces flowers in the spring and summer ranging in color from white to pink. In the early spring and late fall, lamb's ear creates a silvery coating on the ground that some find unappealing. Lamb's ear has a tendency to be invasive and often develops brown leaves near its base. You can remove unwanted or brown growth by pruning your lamb's ear plant in less than 10 minutes. [图片]Step 1 Rinse your scissors or garden clippers to remove dirt and debris with warm water. Wipe the blades dry before sanitizing them with rubbing alcohol. Even though lamb's ear is a hardy plant, you should take these precautions to lessen the chance of infection from pruning. Step 2 Cut dead or browning leaves from the entirety of the lamb's ear plant, allowing only healthy foliage to remain. Make the cuts about 1/4 inch away from the body of the plant, ensuring you do not damage any other leaves in the process. The cut should be as small and clean as possible to lessen the time your lamb's ear must devote to healing. Discard the pruned leaves. [图片]Step 3 Remove areas of the lamb's ear you find unappealing or sections of the plant that have spread beyond their boundaries. It will continue to grow back, requiring regular pruning, but this lessens the overwhelming effect lamb's ear can have on your garden. Cut the unwanted growth as close to the ground or main plant as possible for maximum impact.

Elephant ear plants (Colocasia esculenta) are mostly grown for their showy foliage as they have massive, ornamental leaves. Common names for elephant ear include taro, dasheen and coco yam. Elephant ears are generally planted in spring, once all danger of frost has passed, and only grow outdoors year-round in U.S. Department of Agriculture plant hardiness zones 8b through 11. They can flower from late spring to early fall. Elephant ears can be invasive and are on invasive plants databases for Texas and Florida. [图片]Bloom Period Elephant ears may bloom from spring through to summer with inconspicuous green flowers on long stalks. The flower has a modified leaf or spathe that covers the stalk, while the stalk consists of a cluster of tiny flowers. Flowering depends upon growing conditions and elephant ear plants may not bloom every year. Their showy foliage make up for their lack of attractive flowers. Foliage Color Elephant ears will grow up to 5 feet tall. The various cultivars bring a range of colors. "Black Magic" has burgundy or black foliage, "Chicago Harlequin" produces dark green foliage contrasted with random blotches of lighter green and the green foliage of "Illustris" has lime green veins and edging and is overlaid with black. Pigsqueak Also sometimes called elephant ears, pigsqueak (Bergenia cordifolia) grows in damp, shady areas. It produces tall panicles of pink flowers in spring. These plants grow up to 2 feet tall and are renowned for the vibrant fall colors. Pigsqueak grows in USDA plant hardiness zones 3 through 8. [图片]Pigsqueak Colors Pigsqueak cultivars offer a range of spring bloom colors. "Silver Light" has white blooms, "Ballawlay" produces red flowers, while "Evening Glow's" flowers are magenta. The common variety blooms in pink.
