Description: This herbaceous perennial plant is 2-5' tall, branching occasionally. The larger stems are occasionally reddish, and have lines of white hairs. The alternate leaves are up to 5½" long and ¾" across, becoming smaller and narrower as they ascend up the stems. They are lanceolate, narrowly ovate, or linear, and have smooth margins. Underneath, the leaves are whitish green with a reticulate network of fine veins that is quite conspicuous. The inflorescence is large and pyramidal, containing numerous daisy-like composite flowers from ½–¾" across. Each flower has 20-30 lavender or light blue ray florets surrounding numerous yellow disk florets that eventually become reddish purple. The blooming period occurs from early to mid-fall, and lasts about a month. There is no noticeable floral scent. The achenes develop with small tufts of hair, and are dispersed by the wind. The root system is fibrous and rhizomatous. The Willow Aster often spreads vegetatively to form small to large colonies. Cultivation: The preference is full sun, moist conditions, and fertile loamy soil. Foliar disease occurs occasionally, which may involve some yellowing of the leaves and the formation of black spots. This affects primarily the older leaves near the base of the plant, otherwise the foliage remains attractive. Some standing water is tolerated if it is temporary. [图片]Range & Habitat: The native Willow Aster is widely distributed, and it occurs in most counties of Illinois (see Distribution Map). This plant is occasional to locally common. Habitats include moist black soil prairies, moist meadows along rivers and lakes, thickets, roadside ditches, abandoned fields, and other poorly drained areas. Faunal Associations: Many kinds of insects visit the flowers, including long-tongued bees, short-tongued bees, flies, butterflies, and skippers. Among the bees, this includes such visitors as honeybees, bumblebees, Halictine bees, and some Andrenid bees that fly late in the season. Some Syrphid flies and beetles may feed on the pollen, otherwise these insects seek nectar; bees also collect pollen for their larvae. The caterpillars of the butterflies Chlosyne nycteis (Silvery Checkerspot) Phyciodes tharos (Pearl Crescent) feed on the foliage, as well as the caterpillars of several species of moths (see Moth Table). Various insects suck the juices from this and other asters, including plant bugs, lace bugs, and aphids. The Wild Turkey eats the foliage and seeds to a limited extent. Deer browse on this plant occasionally, while rabbits nibble on the foliage of immature plants. [图片]Photographic Location: The photographs were taken at Loda Cemetery Prairie in Iroquois County, Illinois. Comments: This is another attractive aster for autumn bloom, producing abundant flowers. The Willow Aster can be distinguished from other asters (Symphyotrichum spp.) by the conspicuous reticulated pattern on the lower surface of its leaves. In addition, the stalks of the flowerheads are relatively short and they are covered with relatively large leafy bracts. Unlike many woodland asters, the leaves of Willow Aster are always narrow and willow-like, even at the base of the plant, and they lack serrated edges. The flowers are usually lavender or light violet, although sometimes they are white.

Description: This herbaceous perennial plant is 1½–3' tall and largely unbranched, except near the inflorescence. The central stem is light green, terete, and glabrous to sparsely short-hairy. Alternate leaves occur along the central stem, becoming shorter and more narrow as they ascend. The lower leaves are up to 3" long and 1½" across; they are narrowly oval to ovate in shape and smooth along their margins. The middle leaves are up to 2½" long and ¾" across; they are narrowly lanceolate to lanceolate in shape and smooth along their margins. The upper leaves are up to 1¼" long and ¼" across; they are linear-oblong in shape and smooth along their margins. The upper leaf surfaces are medium to dark green and glabrous or nearly so, while their lower surfaces are light green and glabrous to short-hairy along the major veins. The petioles of these leaves are up to 2" long, becoming shorter as they ascend the stem – however the upper leaves are sessile. The petioles are light green, concave above and convex below, and glabrous to slightly hairy. In addition to the deciduous alternate leaves, this plant also produces a loose tuft of semi-evergreen basal leaves. These basal leaves are similar in appearance to the lower alternate leaves, except they are more broad (oval to oval-cordate in shape) and their margins are sometimes crenate-serrate. The petioles of basal leaves are up to 3" long. The central stem terminates in a panicle of flowerheads that is ½–1½' long and about one-half as much across. When a plant is in bloom, it often leans to one side because of the weight of the inflorescence. Several Flowerheads The panicle has a rachis (central stalk) and several ascending primary branches; these branches divide into secondary and tertiary branches that terminate in daisy-like flowerheads. The rachis and branches are light green and glabrous to sparsely short-hairy; scale-like to linear leafy bracts up to ¾" long occur at intervals along these branches. Each flowerhead is about ½" across or slightly larger, consisting of 10-25 ray florets that surround numerous disk florets. The petaloid rays are lavender or light blue (rarely white), linear-oblong in shape, slightly notched at their tips, and widely spreading. The tiny corollas of the disk florets are tubular in shape with 5 ascending to spreading lobes along their upper rims; these corollas are initially yellow, but they later become purplish red and finally brown. Surrounding the base of each flowerhead, there are scale-like bracts (phyllaries) that are arranged in 3-5 series that are appressed together or slightly spreading. These floral bracts are about 2 mm. long, lanceolate in shape, and mostly light green, except toward their tips, where there are dark green patches that are diamond-shaped. The blooming period occurs from late summer into autumn, lasting about 1 month for a colony of plants. Afterwards, the florets are replaced by small bullet-shaped achenes (about 2 mm. in length) that have small tufts of hair at their apices. These achenes are distributed by the wind. The root system is fibrous and rhizomatous; older plants may develop a short caudex. [图片]Cultivation: The preference is full or partial sun and mesic to dry conditions. This plant is rather indifferent to soil characteristics – it can flourish in soil that is loamy, sandy, rocky, or contains clay. This plant is easy to grow and drought resistant; the lower leaves are occasionally marred by powdery mildew and other foliar diseases. Range & Habitat: The native Sky Blue Aster occurs occasionally in the northern and western halves of Illinois, but it is uncommon or absent elsewhere (see Distribution Map). Habitats include mesic to dry prairies, sand prairies, hill prairies, rocky upland woodlands, upland savannas, upland sandy savannas, woodland borders, sandy meadows, limestone glades, and roadside embankments. This plant is usually found in higher quality natural areas where the original ground flora is still intact. Occasional wildfires or other disturbance that reduce competition from woody vegetation is beneficial in maintaining populations of this plant. [图片]Faunal Associations: For Sky Blue Aster, the nectar and pollen of the flowerheads attract bumblebees, digger bees (Melissodes spp.), leaf-cutting bees (Megachile spp.), Halictid bees (Agapostemon spp., Halictus spp., Lasioglossum spp.), Andrenid bees, Syrphid flies, bee flies (Bombyliidae), butterflies, skippers, miscellaneous beetles, and other insects (Reed, 1993). Bees that are specialist pollinators (oligoleges) of asters (Symphyotrichum spp.) and closely related composites include Andrena asteris, Andrena nubecula, Andrena simplex, Colletes simulans armatus, and Melissodes dentiventris. Other insects feed destructively on the leaves, flowerheads, and other parts of asters. These species include larvae of the Aster Leafminer Fly (Calycomyza humeralis), larvae of the Papery Blister Gall Midge (Asteromyia laeviana), larvae of fruit flies, plant bugs, the Goldenrod Lace Bug (Corythucha marmorata), aphids (especially Uroleucon spp.), the Aster Leafhopper (Macrosteles fascifrons), Blatchley's Walkingstick (Manomera blatchleyi), and grasshoppers (see the Insect Table for a listing of these and other species). In addition, larvae of the butterflies Silvery Checkerspot (Chlosyne nycteis) and Pearl Crescent (Phyciodes tharos) feed on asters, as do larvae of the Aster Borer Moth (Carmenta corni), The Asteroid (Cucullia asteroides), and many other moths (see Moth Table). Among birds, the Ruffed Grouse and Wild Turkey browse on the leaves and seeds of asters; the Tree Sparrow also eats the seeds during the winter. Among mammals, the Cottontail Rabbit and White-Tailed Deer browse on the foliage, while the White-footed Mouse eats the seeds (Martin et al., 1951/1961). Groundhogs, cattle, horses, and other livestock also browse on the foliage, especially when it is young and tender. [图片]Photographic Location: The photographs were taken at the webmaster's wildflower garden in Urbana, Illinois. Comments: For the size of the plant, the inflorescence of Sky Blue Aster (Symphyotrichum oolentangiense) is rather large and showy. This species of aster closely resembles Short's Aster (Symphyotrichum shortii), even though the latter species is a woodland aster. However, the upper leaves of Short's Aster are often narrowly cordate, rather than narrowly lanceolate or linear, and its flowerheads are slightly larger in size. Another similar species, Smooth Blue Aster (Symphyotrichum laeve), has alternate leaves that are all sessile, while Sky Blue Aster has lower to middle leaves with petioles. Other asters (Symphyotrichum spp.) have hairier foliage, or their leaves are narrow throughout, or they have more cordate leaves, or their alternate leaves have toothed margins. Older scientific names for Sky Blue Aster include Aster azureus and Aster oolentangiensis, while another common name for this species is Azure Aster.

Description: This perennial plant is 1-2' tall, branching frequently to create a bushy appearance. The slender stems are rather stiff and slightly pubescent; the lower stems turn brown and become slightly woody during the fall. The alternate leaves are up to 2" long and ½" across, becoming smaller as they ascend the stems; they are typically one-half the maximum size or a little less. They are linear to linear-oblong, slightly pubescent, and smooth along the slightly ciliate margins. These leaves are rather densely crowded along the stems (particularly the upper stems) and sessile. The compound flowers are daisy-like and about 1–1¼" across. Each compound flower consists of about 20-35 blue-violet or purple ray florets that surround numerous disk florets that are yellow or amber. These disk florets later become reddish purple. Each compound flower is subtended by spreading linear bracts that resemble the upper leaves. The blooming period occurs during the fall and lasts about 1-2 months; a robust plant will be covered with flowerheads. There is no noticeable floral scent, although the crushed foliage and flowerheads have a balsam-like aroma. Aromatic Aster is one of the last wildflowers to bloom prior to heavy frost. The achenes have small tufts of light brown hair and are distributed by the wind. The root system is fibrous and rhizomatous; older plants often have a short caudex. There can be significant variability in the characteristics of plants across different locations. Cultivation: The preference is full sun and dry conditions, although an average moisture level is tolerated if the site is well-drained. Poor, rocky soil with open terrain is preferred; a high pH is tolerated. Some of the lower leaves may wither away before the plants begin to bloom, but the foliage usually remains quite attractive. At moist fertile sites, this plant has trouble competing against tall aggressive plants, unless such neighbors are selectively weeded out. [图片]Range & Habitat: The native Aromatic Aster occurs primarily in northern Illinois, the hilly sections of southern Illinois, and in areas bordering the Mississippi and Illinois rivers (see Distribution Map). It is generally an uncommon plant, although locally common at a few exceptional sites. Habitats include mesic to dry gravel prairies, dolomite prairies, gravelly hill prairies, limestone glades, and rocky bluffs along major rivers. Faunal Associations: Many insects visit the flowers, including long-tongued bees, short-tongued bees, small to medium-sized butterflies, and skippers. These insects seek nectar primarily, although the bees also collect pollen. Many kinds of insects feed on the foliage and other parts of asters, including the caterpillars of the butterfly Chlosyne nycteis (Silvery Checkerspot) and many moth species (see Moth Table). The Wild Turkey and possibly other upland gamebirds eat the seeds and foliage to a limited extent. Mammalian herbivores occasionally eat the foliage of asters, even though their food value is low. [图片]Photographic Location: The above photographs were taken in the wildflower garden of the webmaster in Urbana, Illinois. Comments: This aster has attractive flowers and is fairly easy to cultivate in a sunny rock garden and similar areas. Aromatic Aster can be distinguished from other asters (Symphyotrichum spp.) by the number of ray florets per flowerhead (greater than 20), the size of its flowerheads (usually about 1" across or slightly more), and the spreading linear bracts underneath each flowerhead. The leaves are shorter and more narrow than those of many other Aster spp., and they release a pleasant aroma when crushed. In general habit, Aromatic Aster has denser foliage and a bushier habit than other asters, which are usually more tall and lanky. In mass-market horticulture, some plants that are labeled 'Aromatic Aster' appear to be hybrids of Aromatic Aster and Symphyotrichum novae-angliae (New England Aster). These cultivated plants tend to be larger in size and have larger lower leaves; their flowerheads are slightly larger and more double than those of Aromatic Aster.

Description: This herbaceous perennial plant is up to 4' tall, consisting of a central stem that branches occasionally near the top. The central stem and side branches are covered with short white hairs. The alternate leaves are up to 4" long and 1" wide, becoming smaller as they ascend the flowering stems. They are lanceolate or oblong, pubescent, and clasp the stem at the base of each leaf. Their margins are smooth, but ciliate. Clusters of composite flowers occur at the ends of the upper stems. Each composite flower consists of numerous gold or yellow disk florets, which are surrounded by 30 or more ray florets that are purple, lavender, or light pink. Each composite flower is about 1½" across. A mature plant may bear two dozen or more of such flowers, putting forth a showy display. There is no noticeable floral scent. The blooming period occurs from late summer to fall, and lasts about 2 months. The root system consists of a stout caudex with fibrous roots, which often produces short thick rhizomes, enabling this plant to spread vegetatively. The achenes are longitudinally ribbed and slightly hairy, with tufts of hair that enable them to be carried off in the wind. Cultivation: The preference is full or partial sun, and moist to average conditions. The soil can contain loam or clay. This plant can become stressed out by hot dry weather, often dropping its lower leaves in response, while the remaining leaves may turn yellow or brown. Another problem is that the stems often flop over in the absence of supportive vegetation. Powdery mildew often afflicts the leaves during the cool, moist weather of the fall. This is an easy plant to grow in moist conditions, but it is more difficult to maintain in good condition throughout the year. Sometimes it becomes aggressive and spreads vegetatively. [图片]Range & Habitat: The native New England Aster occurs throughout Illinois, except in a few southern counties (see Distribution Map). It is a common plant. Habitats include moist to mesic black soil prairies, clay prairies, thickets, moist meadows in woodlands, open areas along rivers and lakes, fens, abandoned fields, open areas along railroads and roadsides, and miscellaneous waste areas. Some populations are probably escapes from cultivated plants. This plant colonizes disturbed areas readily, but it also occurs in high quality habitats. Faunal Associations: The flowers are visited primarily by long-tongued bees, bee flies, butterflies, and skippers. Short-tongued bees and Syrphid flies also visit the flowers, but they collect pollen primarily and are non-pollinating. Among the long-tongued bees, are such visitors as bumblebees, honeybees, Miner bees, and large Leaf-Cutting bees. Cross-pollination by these insects is essential, otherwise the seeds will be infertile. The caterpillars of many moths feed on various parts of this and other asters (see Moth Table). Other insects feeding on this plant include Lygus lineolaris (Tarnished Plant Bug), Poccilocapsus lineatus (Four-Lined Plant Bug), Corythuche marmorata (Chrysanthemum Lace Bug), and Macrosiphum euphoriaca (Potato Aphid). The seeds and leaves of this plant are eatened to a limited extent by the Wild Turkey, while deer, livestock, and rabbits occasionally browse on the foliage, sometimes eating the entire plant. However, New England Aster isn't a preferred food source for these animals. [图片]Photographic Location: The photographs were taken at Judge Webber Park in Urbana, Illinois. Comments: New England Aster can be variable in terms of its size, color of the flowers, and other characteristics. This plant has attractive flowers with a long blooming period, but it often appears messy by the fall as a result of drought, insects, and disease. It is easy to distinguish this aster from other asters (Symphyotrichum spp.), because its compound flowers are larger in size and they have more numerous ray florets.

Description: This perennial herbaceous plant is 1–3½' tall, branching occasionally. The central stem and lateral stems are light green to dull red, terete, and sometimes shallowly grooved; they usually have vertical lines of white hairs. Older lower stems sometimes become brownish, woody-looking, and glabrous. Alternate leaves occur along the entire length of the stems, becoming gradually smaller in size as they ascend. These leaves are up to 5" long and ¾" across; they are narrowly lanceolate, elliptic, or elliptic-rhombic in shape, while their margins are entire (toothless) or sparingly serrated. Usually the lower to middle leaves have a few teeth along their middle to outer margins, while the upper leaves are entire. The leaves taper to acute tips, while their bases are wedge-shaped (cuneate); they are either sessile or taper gradually into short winged petioles. The upper leaf surface is medium to medium-dark green and glabrous, while the lower leaf surface is slightly more pale and usually glabrous (very young leaves may be sparsely short-pubescent below). A reticulated network of secondary veins is clearly visible on the lower side of each leaf, and sometimes it is also visible on the upper side. During cold autumn weather, sometimes the foliage becomes purple. The central stem terminates in a panicle of flowerheads up to 8" long and 4" across; smaller panicles of flowerheads are often produced from upper lateral stems and the axils of upper leaves. Flowerheads, Leaves, & Leafy Bracts The branches of these panicles are similar to the stems, except they tend to be more hairy and more grooved. Solitary leafy bracts up to 1½" long and 8 mm. across occur where these branches diverge, and they also occur at the bases of peduncles (basal stalks of the flowerheads). These peduncles are up to 1½" long. Each daisy-like flowerhead spans ½–¾" across, consisting of 20-40 ray florets that surround a dense head of numerous disk florets. The petaloid rays of a flowerhead are white and linear-oblong; when a flowerhead is fully open, they are widely spreading to somewhat declined. The corollas of disk florets 3-5 mm. long, tubular in shape, and 5-lobed along their rims; they are initially yellow, but later become orange-red. The lobes of the corollas are triangular in shape and ascending to widely spreading. The ray florets are fertile and pistillate, while the disk florets are fertile and perfect. Surrounding the base of each flowerhead, there are numerous phyllaries (scale-like floral bracts) in several series that are erect to ascending. The phyllaries are 2-4 mm. long, light to medium green, linear-oblong in shape, and glabrous. The blooming period occurs from late summer into autumn for 1-2 months. Afterwards, the florets are replaced by achenes with small tufts of white hair; they are dispersed by the wind. The achenes are about 1.5–2 mm. long, gray to dark gray, narrowly oblanceoloid in shape, slightly flattened, and finely pubescent. The root system is fibrous and long-rhizomatous. Clonal colonies of plants are often produced from the rhizomes. [图片]Cultivation: The preference is full to partial sun and moist conditions. Favored locations are poorly drained areas that form pools of water temporarily, but later dry out. This plant can tolerate average levels of moisture and some drought, but it won't grow as large and its lower leaves may shrivel away. The soil can contain loam, clay, gravel, or even large rocks – this plant doesn't seem to care. Some foliar disease may occur, such as patches of rust or powdery mildew, but the foliage is usually in good shape during the blooming period of autumn. In damp open areas, this plant may spread aggressively by means of its rhizomes. Range & Habitat: The native Panicled Aster occurs in most counties of Illinois (see Distribution Map), where it is common. Habitats include disturbed areas of moist prairies, prairie swales, openings and edges of floodplain woodlands, moist meadows along rivers, thickets, gravelly seeps, low areas along ponds and small lakes, edges of marshes, seasonal wetlands, roadside ditches, poorly drained gravelly areas of junkyards, fence rows, pastures, and abandoned fields. This plant often thrives in moist disturbed areas that are subjected to little or no mowing. [图片]Faunal Associations: The nectar and pollen of the flowerheads attract many kinds of insects, including honeybees, bumblebees, leaf-cutting bees (Megachile spp.), Halictid bees (including green metallic bees), Halictid cuckoo bees (Sphecodes spp.), oligolectic Andrenid bees (Andrena spp.), Crabonid wasps (Ectemnius spp. & others), bee wolves (Philanthus spp.), thread-waisted wasps (Ammophila spp.), paper wasps (Polistes spp.), Eumenine wasps, Ichneumonid wasps, Syrphid flies, bee flies (Bombyliidae), Tachinid flies, flesh flies (Helicobia spp. & others), bottle flies (Lucilia spp.), Muscid flies, butterflies (Vanessa spp. & others), skippers, and beetles. Other insects feed destructively on the leaves and other parts of the Panicled Aster (Aster lanceolatus). These species include the leaf beetles Microrhopala xerene, Ophraella pilosa, Paria thoracia, and Sumitrosis inaequalis; larvae of the leaf-mining flies Nemorimyza posticata, Ophiomyia texana, and Phytomyza albiceps; larvae of Asteromyia laeviana (Papery Blister-Gall Midge) and the gall fly Rhopalomyia asteriflorae; the aphid Uroleucon olivei; and caterpillars of a butterfly, Phyciodes tharos (Pearl Crescent); see Clark et al. (2004), Needham et al. (1928), Felt (1917), Blackman & Eastop (2013), and Opler & Krizek (1984). Other insects that feed on this aster and other asters (Symphyotrichum spp.) include the larvae of fruit flies, plant bugs, several aphids, grasshoppers, and the larvae of many moths. Vertebrate animals also use asters as a source of food. The Ruffed Grouse and Wild Turkey feed on the seeds and foliage of these plants, while the Tree Sparrow and White-footed Mouse feed on the seeds only. Mammalian herbivores also browse on the foliage of asters, including deer, rabbits, groundhogs, horses, cattle, and sheep. In particular, White-Tailed Deer are very fond of the foliage of Panicled Aster, browsing its leafy stems to within inches of the ground (Martin et al., 1951/1961; personal observations). [图片]Photographic Location: The photographs were taken at a rock-filled ditch near Urbana, Illinois. Comments: Panicled Aster (Symphyotrichum lanceolatum) is rather showy when it is in bloom, even though it is often treated as an undesirable weed. This aster can be difficult to distinguish from other asters (Symphyotrichum spp.) that have small flowerheads with white petaloid rays. It has several characteristics that, when they are taken together, are useful in making a correct identification: 1) its flowerheads are usually ½" across or slightly more, 2) its flowerheads have at least 20 ray florets, 3) its leaves have wedged-shaped bases, rather than rounded or cordate (heart-shaped), 4) its mature leaves are hairless on both their upper and lower sides, 5) its stems usually have lines of fine white hairs, and 6) its panicles of flowerheads have conspicuous leafy bracts. Regarding nomenclature, alternative common names for this plant are 'Tall White Aster' and 'White Field Aster,' while older scientific names include Aster lanceolatus, Aster paniculatus and Aster simplex.

[图片]一、土壤要求 硕苞蔷薇盆栽的土壤最好选择5份园土，3份腐叶土，2份砻糠灰混合成的营养土。平时应该注意土壤的通风、排水、营养等，防止硕苞蔷薇出现烂根，营养不良的状况。 栽培完成后，需要在每年冬天前对硕苞蔷薇进行换盆，换土，为来年更好生长做足准备。需要提醒大家一点，花盆最好选择泥瓦盆。 [图片]二、水量控制 硕苞蔷薇浇水量随着季节的变化而有所不同。冬天，植株处于休眠的状态，只要保证土壤湿润，不干燥就可以。 春天的时候，它的枝叶苏醒生长，此时我们可以适当增加浇水量，早晚都要勤浇水。当植株处于生长旺期的时候，水分的需求量比较大，再加上夏季太阳的直射，很容易干燥脱水影响硕苞蔷薇的正常生长。这个生长时期，除了每天早晚需要浇水外，还要尽量避免让植株受到暴晒。 如果有花友在高温的时候浇水，每次浇水量应该以有少部分水从花盆渗出为宜。 三、肥料施用 硕苞蔷薇需要每隔半个月施用一次液肥，能让植株快速生长，也能让叶子更有光泽。早春枝条发芽前，我们需要施用一次浓度高一点的液肥。 在硕苞蔷薇开花的时候不要施用肥料，花谢的时候再施肥就可以。进入休眠期的植株需要施用有机肥。 [图片]四、修剪枝条 每次硕苞蔷薇花开后，需要修剪枝条。修剪的程度不要过大，只需要及时修剪那些凋零的花朵和瘦弱的枝条就可以。 整体的花型为了美观可以修剪成爱心，不但增强观赏性而且还能延长花期，让我们可以有更长的时间欣赏硕苞蔷薇花的美丽。 [图片]

[图片]一、白粉病 1、症状 叶片会生长出白色的霉斑，大的病叶最终变成褐色；嫩叶染病后叶片会变为紫红色最终覆上一层白粉，严重时叶片逐渐枯萎。 2、原因 因为病菌在植物内越冬，到等温度升高至二十度以上就到了发病的时期，所以4—5月、9—10月为发病高峰期，也就是说蔷薇花的病害与气温息息相关。 3、如何预防 大家应选择抗白粉病的硕苞蔷薇品种进行种植，同时冬季要对其进行修剪，及时清除病枝，从源头杜绝蔷薇的生病。 4、注意事项 要减少病害，要适当通风、透光，少施氮肥。使用药物时，要注意使用的安全间隔期，不可任意加量和缩短间隔期。 [图片]二、虫害 1、金龟子 养过这种植物的人应该在叶片上见过金龟子，常年种植的人可能会说这是一种健康的表现，代表植株并没有撒过药，可是我们应该知道，如果植物有一只金龟子那无关紧要。但是过多的虫害就是灾难了，金龟子喜食蔷薇的根茎、叶子。严重将影响花朵的产量和质量。 防治方法：可采用灯光、杨柳等方式吸引金龟子，从而减少其数量。 [图片]2、刺蛾 植物较为年长时，会很大程度吸引刺蛾，一般蔷薇的虫害时间主要集中在夏季炎热的夏季，最为严重的时期是夏末，气温高对刺蛾的发育其正作用。刺蛾会吃掉叶片，植物光合作用、生长发育的工具都无法具备，更无法成长，若是叶片在此期间得病，则这盆花可能损失过重，不幸死亡。 防治方法：冬季及时检查 是否有虫卵，应及时清楚掉虫卵。

[图片]繁殖方法一：播种 我们在植物繁殖时多会采用播种方式，在春天我们需要将沙藏的硕苞蔷薇种子用水浸泡30分钟，然后播种在土壤的表面，土壤必须保持湿润的状态。播种后盖上一层薄膜，保证充足的光照，3到4天洒一次水，出苗后就可以进行移栽了。但是不建议采用播种培育的方法，这种方式的成活率比较低，如果有的花友想尝试也不妨。 [图片]繁殖方法二：分株 将硕苞蔷薇新生出来的小枝条与母株相连接的地方分离，然后放入土壤中进行栽植，耐心等待小的枝条成长为新的植株。这种分株繁殖的方法相对容易，成活概率也比较高，推荐给大家。 [图片]繁殖方法三：扦插 硕苞蔷薇的繁殖也常常采用扦插的方法。要用嫩的枝条作为扦插的育苗，这样比较容易成活。 插穗最好选择生长比较健硕的枝条，并需要用心处理，最好立即进行扦插，提高成活率。我们也可以在插穗的切口处涂抹一些草木灰，能够很好的起到防止腐烂的作用。扦插的硕苞蔷薇最好能够保持温度在20度到25度之间，温度过高容易引起切口处的腐烂，温度过低会影响生长。 [图片]繁殖方法四：压条 硕苞蔷薇的压条育苗法是将植株的枝条压入湿润的泥土中，等到枝条生出根系时，将它与母株分割开，移栽土壤中，形成新的植株。压条法同样是植株成活率很高的方法，而且能够保持原硕苞蔷薇的样子。 压条法和分株法很适合没有太多经验的花友，播种法和扦插法的难度略高一些。如果大家能够很好控制温度条件的话，扦插法繁殖硕苞蔷薇一年四季都可以进行。除了控制温度外，扦插法还要注意空气的湿度和流通度。了解了这么多，大家赶紧行动起来繁殖硕苞蔷薇。
