Description: This perennial plant is up to 1' tall, branching occasionally and rather bushy when mature. There are scattered hairs along the stems, and the opposite leaves are ciliate, but without serration. The leaves are oblong-lanceolate, broadly lanceolate, or ovate. Each leaf is about 1-2" long and about one-third as wide, with a prominent central vein and a smoothFlowers texture. At the ends of the stems are clusters of small flowers. These flowers are usually white or light purple, but sometimes a darker shade of purple. Each flower is about ¼" across, with a short tubular shape and four lobes that flare outward. The reproductive parts are white, except for the light brown anthers. The flowers bloom during late spring or early summer for about a month. There is no floral scent. The small seeds are distributed to some extent by the wind. The root system consists of a branching taproot. Cultivation: The preference is full or partial sun, and moist to slightly dry soil. This plant typically grows in soil that is loamy or rocky. It is not usually bothered by foliar disease, and is one of the easier bluets to maintain in an average garden situation. Range & Habitat: The native Lance-Leaved Bluets occurs occasionally in the southern half of Illinois, while in the northern half of the state it is rare or absent (see Distribution Map). Habitats include mesic black soil prairies, rocky upland forests, rocky bluffs, limestone glades, borders of lakes, and pastures. This wildflower is found primarily in higher quality natural areas. Faunal Associations: The flowers attract long-tongued bees, short-tongued bees, flies, small butterflies, skippers, and beetles. Bee visitors include Little Carpenter bees, Nomadine Cuckoo bees, Halictine bees, and Panurgine bees. Other common insect visitors include Syrphid flies, Checkerspot butterflies, Copper butterflies, White butterflies, and Flower Scarab beetles. The seeds of this plant are too small to be of much interest to birds. Limited information is available regarding this plant's attractiveness to mammalian herbivores. Photographic Location: The photographs were taken at Loda Cemetery Prairie in Iroquois County, Illinois. [图片]Comments: This unassuming little plant is a good candidate for a rock garden, in either sunny or partial shaded areas. It is easily overlooked in the wild, but when it is found in bloom this is always a pleasant surprise. Lance-Leaved Bluets can be distinguished from other bluets by the wideness of its leaves – up to 2/3" (17 mm.) across. Other species of bluets in Illinois have narrow to very narrow leaves. An exception is Houstonia purpurea (Wide-Leaved Bluets), which has leaves up to 1¼" wide, sometimes with 3 conspicuous veins. This latter species occurs primarily in woodland areas in extreme southern Illinois. Lance-Leaved Bluets is sometimes considered a variety of this species: Hedyotis purpurea calycosa or Houstonia purpurea calycosa, depending on the authority.

Description: This small perennial wildflower is about 3-6" tall, consisting of a rosette of basal leaves and one or more flowering stems with opposite leaves. The basal leaves are about ½" long, medium green, elliptic or oblanceolate in shape, glabrous, and smooth along their margins. The unbranched stems are light green, 4-angled, glabrous, and more or less erect. The opposite leaves, which are widely spaced along each stem, are ¼" long or less, medium green, linear-elliptic in shape, glabrous, sessile, and smooth along their margins. Each stem terminates in 1-2 flowers (usually only one). The flowers have slender pedicels that are light green and glabrous. Individual flowers are 3/8" (10 mm.) across, consisting of a light green tubular calyx with 4 linear lobes, a narrowly tubular corolla with 4 petal-like lobes, 4 stamens, and a pistil with a single style that is bifurcated at its tip. The petal-like lobes of the corolla are pale blue-violet (rarely white), ovate in shape, and widely spreading. At the base of the lobes, the corolla is yellow. [图片]Two types of flowers are produced: those with long stamens and a short style, and those with short stamens and a long style. Regardless of the flower type, both stamens and style are inserted within the corolla or barely visible at its mouth. The blooming period occurs during the late spring and lasts about 3 weeks. The flowers are replaced by 2-lobed seed-capsules about 1/8" (3 mm.) across. The capsule contains several small seeds with minute pebbly surfaces (when viewed under magnification). This wildflower has shallow fibrous roots and slender rhizomes, forming tufts of flowering plants. Cultivation: The preference is full or partial sun, moist to dry-mesic conditions, and either sandy or thin rocky soil that is somewhat acidic. Most growth and development occurs during the spring. This wildflower will adapt to rock gardens. [图片]Range & Habitat: The native Quaker Ladies is found along the easternmost tier of counties and scattered areas of southern Illinois (see Distribution Map). It is an uncommon species in this state. Habitats include sand prairies, sandy savannas, sandy paths in wooded areas, sandstone glades and ledges, and damp rocky areas along upland streams. This wildflower occurs in higher quality habitats with sparse ground vegetation. Faunal Associations: The flowers of Quaker Ladies attract Little Carpenter bees (Ceratina spp.), Green Metallic bees and other Halictid bees, bee flies (Bombyliidae), and small butterflies. Blanchon (1901) observed the butterfly Boloria bellona (Meadow Fritillary) as a frequent visitor of the flowers. Both nectar and pollen are available as floral rewards. According to Covell (1984/2005), Houstonia spp. (Bluets) are host plants for caterpillars of the moth Thyris maculata (Spotted Thyris). It is doubtful that mammalian herbivores make much use of the foliage of Quaker Ladies, considering its low stature and sparseness. Photographic Location: A mossy path in a sandy woodland in NW Ohio near the Oak Openings region. Comments: This wildflower is dainty, delicate, and wonderful. It is perhaps the most aesthetically pleasing of the small wildflowers in its genus. In Illinois, Quaker Ladies can be distinguished from other Bluets (Houstonia spp.) by the patch of yellow at the center of its corolla. In addition, the opening of its corolla is more narrow than most Bluets and the lobes of its corolla are relatively larger in size and more widely spreading. A species that does not occur within the state, Mountain Bluets (Houstonia serpyllifolia), shares these characteristics with Quaker Ladies. Mountain Bluets differs by having oval-shaped basal leaves that creep across the ground. This latter species is found primarily in the Appalachian mountains. Other common names of Houstonia caerulea are Azure Bluets and Innocence.

Description: This herbaceous perennial plant forms a low rosette of basal leaves, from which a flowering stalk about 2-5' tall develops. Alternate leaves occur along the lower one-half of this stalk, becoming smaller in size and more widely separated above. The unbranched central stalk is pale green, terete, and rather stout. This stalk is densely long-hairy below, becoming sparsely long-hairy and/or short-pubescent above; the long hairs are either white or brown. The basal and lower alternate leaves are 3-8" long and ¾–1¾" across; they are usually oblanceolate in shape and their margins are entire (toothless). The middle to upper alternate leaves are linear-lanceolate or elliptic in shape and their margins are entire (toothless). The basal and lower alternate leaves have long white hairs or long brown hairs that are 1/3–1" in length; these hairs are most abundant along the margins, central veins, and bases of the leaves. The upper surface of both basal and alternate leaves is medium green, while the lower surface of these leaves is pale green. The central stem terminates in a cylindrical panicle of flowerheads about ½–1½' in length; this panicle is longer than it is across. Both the lateral branches and peduncles (basal stalks) of the flowerheads are short (less than 2½" in length). The central stalk, lateral branches, and peduncles are pale green, terete, and glandular-hairy. The flowerheads are ½–1" across when they are fully open, consisting of 30-80 fertile ray florets and no disk florets. The spreading petaloid rays of these florets are yellow and linear in shape; their tips are truncate and 5-toothed. The base of the flowerhead is cylindrical-campanulate (cylindrically bell-shaped) or cylindrical-urceolate (cylindrically urn-shaped); it is surrounded by several phyllaries (floral bracts) in a single series. These phyllaries are linear-lanceolate in shape, appressed, pale green, and glandular-hairy. Some of the glandular hairs on the phyllaries have black bases. There are also secondary floral bracts that are much smaller in size; they are located at the base of the flowerhead. The blooming period occurs from mid-summer to late summer, lasting about 1 month for a colony of plants. Afterwards, the florets are replaced by achenes with tufts of tawny hair at their apices; they are distributed by the wind. The achenes are 3-4 mm. long, dark-colored, and fusiform (spindle-shaped); there are no thread-like beaks connecting the tufts of hair to the achenes. The root system consists of a caudex or short crown with fibrous roots. [图片]Cultivation: The preference is full sun, mesic to dry conditions, and soil containing loam, clay-loam, sand, or rocky material. Range & Habitat: Long-bearded Hawkweed is a native plant that has been found in most areas of Illinois, although it is now widely scattered and uncommon (see Distribution Map). Populations of this plant have declined with the destruction of prairie habitat. Habitats include black soil prairies, clay prairies, sand prairies, prairie remnants along railroads, typical savannas and sandy savannas, upland rocky woodlands, and disturbed areas along railroads. Long-bearded Hawkweed occurs primarily in high quality natural areas. [图片]Faunal Associations: Very little is known about the floral-faunal relationships for Long-bearded Hawkweed. Gangwere (1961) reported that Spharagemon bolli (Boll's Grasshopper) feeds on the dry leaves of this plant. The flowerheads of hawkweeds (Hieracium spp.) are cross-pollinated primarily by little carpenter bees (Ceratina spp.), Halictid bees (including green metallic bees), and other bees. Some aphids feed on the sap of these plants, including Nasonovia ribisnigri (Currant-Lettuce Aphid) and Uroleucon sonchi (Sow Thistle Aphid); see Blackman & Eastop (2013). The Ruffed Grouse and Wild Turkey feed on the basal leaves and seeds of hawkweeds, while their foliage is sometimes browsed by the White-tailed Deer and Cottontail Rabbit (Martin et al., 1951/1961). However, Georgia (1913) states that cattle and other domesticated livestock usually avoid the hairy bitter foliage of these plants. [图片]Photographic Location: A prairie in Fayette County, Illinois. The photographs were taken by Keith & Patty Horn (Copyright © 2015). Comments: The native Long-bearded Hawkweed can be distinguished from other hawkweeds (Hieracium spp.) by the exceptionally long hairs (1/3–1" in length) of its basal leaves, lower alternate leaves, and lower flowering stalk. Other hawkweeds in Illinois have hairs that are less than 1/3" long. In addition to having shorter hairs on its foliage, a similar native species, Hieracium gronovius (Gronovius' Hawkweed), has slightly smaller flowerheads with fewer ray florets (20-40). Another common name of Hieracium longipilum is Long-haired Hawkweed.

Description: This perennial herbaceous plant is 1-3' tall, consisting of a rosette of leaves from which a flowering stalk develops. The basal leaves are up to 6" long and 2" across, tapering to a narrow petiole. They are ovate or oblanceolate, usually with smooth margins, and have scattered white hairs that are ½" or less. The flowering stalk is variably hairy, with a few small leaves alternating along the lower half. The upper half of the stalk is either leafless, or has a few tiny leaves that resemble bracts. Generally, the lower stalk is conspicuously hairy (particularly near the bases of the leaves), while the upper stalk has few or no hairs, except where the flowers occur. This stalk terminates in a panicle of composite flowers. Each composite flower is about ½–¾" across, consisting of a head with 15-30 yellow ray florets. The ray florets have tips that are truncated, ending in 5 small teeth. The blooming period is mid-summer to early fall, and lasts about 1-2 months. Beneath the ray florets, there is a cylindrical arrangement of narrow bracts. These bracts are green or purplish green. The slender stems within the panicle have glandular hairs that are ½" or less; like the bracts, these stems are green or purplish green. The florets are eventually replaced by achenes with white or brown tufts of hair. These achenes are spindle-shaped, tapering at both ends; they are dispersed by the wind. The root system consists of a short crown with fibrous roots underneath; sometimes rhizomes are produced, enabling vegetative reproduction. Cultivation: The preference is full sun to light shade, and moist to slightly dry conditions. Gronovius' Hawkweed normally grows in soil that is sandy or rocky, which reduces competition from other plants. The height of this species is variable, depending on such factors as light and moisture levels. Range & Habitat: The native Gronovius' Hawkweed is scattered throughout Illinois, except for many counties in the NW and central areas of the state (see Distribution Map). Depending on the area, it is occasional to rare or absent. Habitats include moist to mesic sand prairies, sandy thickets, openings in rocky or sandy woodlands, savannas, bluffs, and edges of fields. Where this plant grows in shade, it is usually taller and grows in drier locations. Where it is sunny, this plant is usually shorter and prefers moister locations. Faunal Associations: The nectar or pollen of the flowers probably attracts many kinds of insects, including long-tongued bees, short-tongued bees, bee flies, and beetles. The seedheads are eaten by the Wild Turkey, while the foliage is eaten by mammalian herbivores, including deer and rabbits. [图片]Photographic Location: Along a sandy path in a Black Oak savanna at Hooper Branch Savanna Nature Preserve in Iroquois County, Illinois. Comments: Another common name for this species is Hairy Hawkweed, although this name is also used for Hieracium longipilum. The Hieracium spp. are another group of plants that can be tricky to identify. They fall into two broad groups: short stoloniferous plants that consist of leafy rosettes, and taller plants with a flowering stalk that is more or less leafy. The former group is dominated by introduced species from Europe, while the latter group consists of native species. Gronovius' Hawkweed is similar in appearance to Hieracium longipilum (Hairy Hawkweed) and Hieracium scabrum (Rough Hawkweed). It differs from the former by having fewer and shorter hairs of ½" or less, and differs from the latter by the absence of leaves on the upper flowering stalk that are any larger than tiny bracts. Gronovius' Hawkweed has spindle-shaped achenes (tapering on both ends), while Rough Hawkweed has bullet-shaped achenes that taper only at the bottom. Other native Hieracium spp. have hairless foliage and stalks, conspicuous teeth along the margins of the leaves, or flowers that are 1" across or more.

[图片]金钱树又名雪铁芋，中国引入时间是1997年，从荷兰引进在广州芳村和顺德陈村露面。1999年中国昆明世博会上，人吔仲唔知其喊作乜嘢名，仅以其外部形态特征将其称作“金钱树”或“金币树”。它的学名为Zamioculcas zamiifolia ，作为一种以观叶为主的常绿草本植物，其拉丁文的种加词“zamiifolia”，意为“泽米叶的”，也就是说它是一种叶片同泽米苏铁（Zamia furfuracea）很相似的天南星类植物，即“泽米叶天南星”。“金钱”、“金币”之名，可能与其叶轴上的叶片形状、质地、排序有关，它的圆筒形叶轴粗壮而肥腴，其上的小叶呈偶数羽状排列，且叶质厚实、叶色光亮，宛若一挂串连起来的钱币。以树命名，主要是因其叶轴直立硕壮，从外表看有木本植物的质感，因而被称作“树”类。中国广东的钟志权先生撰文，建议将其名称改作“赞美叶”，理由有三：一是种加词的译音就有赞美之谐音；二是该植物并非木本植物，主要观赏部位为叶片；三是叶片长势趋上，有仰尚赞举之意表。 [图片]一、金钱树的生长习性在了解金钱树冬季的养护方法之前，我们先了解一下金钱树的生长习性。金钱树喜欢温暖，较为干燥的生还环境，由于地处非洲东部，全年温差小，因此金钱树也适合在温度变化小的环境下生长。适合的生长的温度在20℃～32℃之间，耐旱不耐寒，忌强光暴晒。二、金钱树冬季的养殖方法 1.温度冬季最好能维持在10℃以上的棚室温度，若室温低于5℃，易导致植株受寒害进而严重危及其生存。秋末冬初，当气温降到8℃以下时，应及时将其移放到光线充足的室内，在整个越冬期内，温度应保持在8℃~10℃之间，这样比较安全可靠。 2.光照对冬季移放到棚室内的盆栽植株，应给予补充光照。盆土水分保持偏干，植株可保持长年无病。别外新抽的羽状复叶并不表现为明显的趋光性，株型良好。 3.水分在冬季应特别注意盆土不能过分潮湿，以偏干为好，否则在低温条件下，盆土过湿更容易导致植株根系腐烂，甚至全株死亡。 4.肥料当气温降到15℃以下后，应停止一切形式的追肥，以免造成低温条件下的肥害伤根。 5.防寒保温当冬季气温降到5℃以下，再加上盆土潮湿，易导致植株羽状嫩叶因寒害而倒伏，严重时会引起块茎腐烂，很难再恢复其生机。防治方法：无论是生产性栽培，拟或是家庭种养，越冬期间的棚室温度都应维持不低于10℃，并保持盆土稍呈干燥的状态。少量盆栽，在特别寒冷的日子里，可于夜晚套罩双层塑料袋，次日温度回升后再解去套袋。以上就是亲农网为大家介绍的有关金钱树的养护，金钱树摆放在家中除了有观赏价值之外，还有吸附空气中灰尘等有害气体、释放氧气的作用，既美观又实用，还非常适合摆放在刚装修的房子中，喜欢的朋友不妨选择在天气比较好的时候，买上这么一盆放在家中哟！

[图片]圆叶竹芋：竹芋科，肖竹芋属多年生常绿草本观叶植物。株高可达80厘米，叶片硕大，薄革质，卵圆形，新叶翠绿色，老叶青绿色，有金属光泽，头状花序，小苞片膜质；萼片近相等；花冠管与萼片硬革质，种子三角形。原产美洲的热带地区，生长在热带雨林中。中国有引种栽培。由于该植物耐阴，甚适合家庭居室内装饰美化、绿化之用。可在较明亮的房间内长期摆放观赏，在光线较暗的房间内放置4-6周，对其生长也无太大的影响，所以可以长期在较暗的房间内摆放，亦能生长良好。 [图片]一、圆叶竹芋的生长习性圆叶竹芋是一种生长在热带雨林区域的植物，但它却不是很符合大部分热带植被的耐热的特性，圆叶竹芋最适宜的生长温度在18℃到25℃之间，不耐寒冷和干旱，同时也不耐烈日的暴晒和干热风的吹袭；但同时它也继承了热带雨林植物喜欢高湿的特性，在新叶生长期要多向叶片喷水，如果空气中水分不足，新叶会舒展不开，老叶也会逐渐焦黄，下面我们来具体看一看圆叶竹芋的生长习性。二、圆叶竹芋的养殖方法 1.温度圆叶竹芋喜温暖平和的环境，因此不耐炎热，怕高温，耐寒性差，其生长环境适合的温度在18-30℃。春末夏初时环境温度超过25℃，要进行搭棚遮荫，环境喷水来创造一个凉爽通风潮湿阴暗的环境。冬季环境温度不可低于10℃，如果室温低于5℃圆叶竹芋就睡收到严重的冻害。一般来讲，在秋季末，就应当将竹芋及时搬到室内阳光充足的地方进行保护和越冬了。 2.光照圆叶竹芋喜半阴，忌高温的暴晒，切忌叶片不可出现严重的灼伤。导致叶片暗淡无光泽，失去本来应有的美感。因此在冬季应当将其放置于温室当中进行补充光照。日常生活中可以摆放在室内作为盆栽观赏，应当置于有充足散射光照的窗前。 3.水分圆叶竹芋喜湿润的环境，因此生长季节每天要浇一次透水，还要加强页面和环境周围的喷雾，保持一定的湿润不可过于干燥。冬季严格控制浇水，盆土过湿会导致排水不畅，根部腐烂，使叶片出现枯萎的现象。当春满花开后植株会重新抽出新叶。新叶的萌发也不可过多的浇水，要伴随新叶的增多，逐渐增加浇水量，有利于植株的健康生长。 4.施肥圆叶竹芋在生长期内，要每周施加一次稀薄的有机肥。盆栽植株适合放置在居家和公共场所进行观赏。进入夏季高温季节，当温度高于32℃时，应当停止对圆叶竹芋的施肥。秋末冬初，停止一切追肥，否则会造成植株烂根的现象。以上就是亲农网为大家带来的有关圆叶竹芋的养殖方法，圆叶竹芋除了观赏外，还能够净化空气中的甲醛和氨气，它的根茎中含有淀粉，可以入药，有着清肺热、利尿的作用。有想法在家中摆放一盆绿植的朋友可以考虑入手哟！

[图片]春之奇迹也就是薄毛万年草为景天科多肉植物，这个种类有个优点：生长非常迅速，而且叶插扦插存活率也很高拿到后首先需要让肉肉们恢复生长状态，适应新环境，然后就可以各种叶插、扦插了不出半年，就会变成一小片，养到一年的话基本就是满满一盆了。 [图片]一、徒长原因 1.光照不足这种植物的确非常喜欢光照，这是源于原产地墨西哥的气候造成的。在充足的太阳光的抚育下，这种植物能够进行它所需要的生物作用，吸收阳光的同时展现出迷人的粉色，而且还能使得植株能够爆盆，紧紧凑凑地长在一起，不会造成徒长的情况。 2.水量控制不好浇水量过多，虽然这种植物的生长期间需要水分，但是如果水分太多，没有相匹配的阳光满足它的要求，它就只会长成瘦瘦长长的样子，并不能满足观赏者的观赏要求。二、解决办法 1.给它大量的光照在天气允许的状况下一定要给它多多晒太阳，只有充足的光照才能让它满满地爆盆，如果只是控制了水分，并没有给它大量的光照，这样的种植方式只会让它的植株越来越小甚至会死掉，在阳光充足的地方养育它才是阻止它只会徒长的关键。 2.适当的水分浇水量大会让它徒长，如果浇水量太少，它只能长得很慢，所以说水分的控制对于它的成长来说也很重要。要养育它，只能在满足水分的同时增加光照。依据种植地方的气候进行浇水，成长的时候基本上是维持在一个星期或者两个星期一次就好。三、注意事项 1.控制温度成长环境的温度不可以比30度还要高，但是如果温度高达30度的话，可以给它控制水分。 2.控制湿度春之奇迹的生长环境不能太干，太干会造成植株的干枯，太湿又会导致植物的黑化腐烂。 3.满足光照所需一定要给它充足的光照，不然这种植物的徒长只会成为一种常态，要让他满满当当地爆盆又不会长成瘦瘦长长的样子，一定给它要多晒太阳。以上就是亲农网为大家带来的有关春之奇迹徒长的处理办法，春之奇迹的繁殖方式可以采用扦插和叶插的方式，成活率高，生长速度也比较快，如果养殖得好，可以看到它的叶片由翠绿变为粉红，也是一种十分美好的观叶植物。

Description: This herbaceous perennial plant consists of a rosette of basal leaves. The mature leaves are about 3-5" across, palmately lobed, and orbicular or slightly cordate in shape. Their margins are coarsely serrate or dentate, often with straight white hairs along the major veins on the underside of each leaf. The petioles are longer than the leaves. They have straight white hairs that are quite long and conspicuous. From the center of the rosette emerge several flowering stems that are 2-4' tall. These stems are without leaves and have straight white hairs like the petioles. Each stem terminates in a narrow panicle of green flowers. Sometimes the flowers have reddish tints when exposed to the sun. Each flower is about 1/8" (3 mm.) long, consisting of a bottle-shaped calyx that is divided into 5 lobes. There are 5 inconspicuous petals within the calyx, while 5 stamens with orange anthers are exerted beyond the calyx. The blooming period is usually early summer, and lasts about a month. There is no floral scent. Small capsules develop, containing tiny unwinged seeds, which are dispersed by the wind. The central root stock is stout and short, dividing into coarse roots. Cultivation: The preference is light shade to full sun, and mesic to dry conditions. This plant prefers rocky soil, but will grow in clay-loam,loam, or sandy soil. Once established, it is an easy plant to grow. Range & Habitat: The native Prairie Alumroot occurs occasionally in the northern 2/3 of Illinois, but is rare or absent in southern Illinois (see Distribution Map). Habitats include upland areas of black soil prairies, hill prairies, gravel prairies, sand prairies, limestone glades, and rocky upland woodlands. Generally, Prairie Alumroot favors areas with poor rocky soil where there is reduced competition from taller plants. Faunal Associations: Small bees pollinate the flowers, including Halictid bees and Plasterer bees (Colletidae). The seeds are too small to be of any interest to birds, while the relationship of this plant to mammals is uncertain. [图片]Photographic Location: The photographs were taken at the edge of the postage stamp prairie of Dave Monk in Champaign, Illinois. This plant was underneath a small tree. Comments: This plant has a similar appearance to Heuchera americana (Common Alumroot). Generally, Prairie Alumroot has straight white hairs on the petioles of the leaves and the flowering stems, while Common Alumroot has short appressed hairs (lying against the flowering stems or petioles), or is devoid of conspicuous hairs. The flowers of Prairie Alumroot are slightly larger in size (about 1/8" or 3 mm. long), while those of Common Alumroot are about 1/10" (2.5 mm.) long. The flowers of Prairie Alumroot are often longer at the top than the bottom, while those of Common Alumroot are more symmetrical. Across different localities, there are significant variations in the characteristics of this plant, and different varieties have been identified. In Illinois, var. grayana has flowers that are strongly asymmetric, while var. affinis (as illustrated in a photograph above) has flowers that are only slightly asymmetric. Plants with reddish leaves and silver markings have been introduced by the nursery trade, which are sometimes grown in flower gardens. The wild plant, however, isn't very showy.
