秋田
[图片]一、制作的步骤 1、首先需要把原料准备好，按照自己的爱好来选择就可以了。如果按照一般的材料，是需要苔藓，土还有粗线的。这个是很需要创意的，它才能有不一样的风格，每个人使用的工具不一致，所以制作的步骤可能也不一样，只要目的达到了就可以了。 2、首先把想要做成苔玉的盆景，最好是小型的盆栽，把它根上面的土给清理干净，在这个过程中注意不要伤害到它的根，然后把这一棵比较小的热带花卉根上面的土给洗干净。 3、把煤炭和专用的盆景土搅拌起来，按照7比3的比例，把它的根部给包上，然后把它捏成一个球的形状。把它裹上一层苔藓，然后用比较粗的绳子把它给固定住，其它可以固定的办法也是可以的。然后在把它放进一个漂亮的盆中，整个步骤就完成啦！ [图片]二、养护的技巧 1、给它泡水1次，可以让它保持湿润十来天。夏秋时节屋内比较干燥，可以给它每天喷2次水，下雨的时候可以把它放在雨中，这样它可以长得更加快，这是因为雨中有很多它需要的营养。 2、它适合居住的环境和人的差不多，都需要保持一定的湿度，要让它通风，让它透气，还需要给它充分的光照。它不适合在阴暗的区域成长，需要一定的散光或者是半阴凉的环境。在养护的时候，要给它一定的光，而且最好不要太强，不要是直射的光。 [图片]3、每天要多给它喷几次水，不要一次性浇太多的水，让它保持湿润就可以了。它最适合成长的温度在二十五摄氏度，所以在冬天要把它放在屋内。 4、它和其他的植物有很大的不同点，首先它的根只能固定，吸收水和养分主要依靠叶。然后湿度不够它就会休眠，叶会变成灰绿色，这并不是它死亡了，这个时候的它反而非常强健，不害怕严寒和酷暑，只要一碰水就能恢复翠绿的状态。 [图片]

莲雾是热带水果，原产地一般都是湿热的气候，现在不少北方的朋友都喜欢盆栽热带水果，那么莲雾可以在北方盆栽吗?原则上是可以的，但是要注意养护环境，能否让莲雾顺利过冬。 [图片]实话讲，就目前来说盆栽莲雾的并不是很多，特别是北方，因为要注意温度和湿度，如果想种好莲雾，冬季要有暖气，最低温度不能低于10℃(以选择的品种为准，有的品种不耐冻，有的品种稍耐冻，比如吃飞弹和黑金刚莲雾不耐冻，大叶莲雾耐寒，最低温度3℃)，而且要注意保湿，能满足这些条件，我们再看下面。 [图片]1、选品种 盆栽莲雾选品种也很重要，一般我们可以选用血红(大红)种作为盆栽的品种，效果很好。 如果想盆栽结果实一定要直接买苗，用种子播种适合做盆栽玩玩。 2、花盆、土壤的选择，种莲雾花盆直径要在40-50cm。而莲雾对土壤要求则不是很高，可以用70%-80%的比较肥沃的土壤(塘泥、腐殖土、老园土、菜园土)、10%-15%的粗砂、10%-15%的碳化稻壳混合配制而成。 3、浇水，莲雾喜好湿润的土壤，周年均需有充足的水分供应。凡水边的莲雾，生长必壮，且耐涝性也强，经常受浸的地区也正常生长，开花结果。所以即便是盆栽的莲雾也要注意补足水分。 4、修剪，对已结果的树每年采果后进行一次修剪，将枯枝、过密枝、徒长枝剪除，自主干和主枝上发生的萌芽也随时抹除。除此之外，修剪要和产期调节相结合。 5、换盆，为了保证莲雾生长，我们可以每年换盆土一次，一般在3月落果之后进行。

看到有花友问及菊花需要打顶吗?索性就跟花友科普一下，打顶和摘心、打头意思一样，但是什么时候打顶要依据菊花苗的情况来判定，我们打顶的目的是为了促进分枝或者是控制植株高度等。一般我们在菊花小苗的时候就要开始打顶，这样比较容易控制，根据不同的需求打顶的技巧也是不一样的。 [图片][图片]比如想养小菊花球， 那么需要多次打头，若是养大菊三本，我可以选择在5月份扦插，6月份上盆，打头，新枝就会出现三到五个。 简单的说就是利用打头或者摘心等操作，迫使植物多发新枝，从而达到多开花的目的，如果花友喜欢植株高，花少一点也可以，那么不需要打顶，任由菊花自己生长就可以了。打顶、摘心之类操作主要是盆栽菊花为了达到植株漂亮，花多效果进行的操作。 什么时候打顶合适呢，如果我们是从小苗就开始种植的，建议在15公分左右的时候就开始打顶，当然要结合实际需求来。不需要过度刻板，因为菊花比较容易发新枝，所以只要菊花植株长势健康，打顶操作可以自由一点。

[图片]一、环境 我们要给它它所喜爱的环境，这样子它才能够长得好。一般来说，它生活的土需要是微酸性的，而且栽的深度不能超过盆子里面苗的上方。此外，我们给它的温度需要在十七至二十六这个区间，如果温度超过了也没关系，但是要在三十五度以下。至于冬日的话，要让它处于七度以上的环境里，在温度比较高的时候我们要经常打开门窗，通风的状态对它而言是比较好的。 二、光照 我们要把它放置在有阳光的地方，因为光照比较多或者是温度比较高对它而言是可以促进分枝的，但是在夏天我们要注意别让它晒伤了。 [图片]三、浇水 在它长得比较旺盛的时候，我们要给它多浇水，而且有必要可以往它的叶子上喷洒一些水，冬天的话就不用浇太多，每次浇水要浇透。 四、施肥 施肥是促进它爆盆的非常重要一点，在它的生长期间我们要十五天就施一次肥，在它刚长出来的时候主要的肥料是氮肥，在五月份左右我们给它增加磷和钾肥，在九月份不能再施加氮肥了，钾磷则需要再施加两次。此外，每个星期要施加全元素的肥料，在冬季施肥就是不需要的。 [图片]五、换盆 春天我们要给它换一次盆，之后它才会长得好。我们把它从土里弄出来，然后把烂掉的根都剪掉，之后用新的土重新栽。 六、修剪 修剪能够让它长得更好。我们一般配合翻盆修剪，把它长得过密或者比较弱小的都剪掉，如果是生长时间比较久的老株，我们要多加修剪，而且之后要追肥。在开花之后也要把凋了的剪掉。等到它的苗长得比较大的时候，我们要给它摘心，这样子花期也会推迟。 [图片]

[图片]1、温度 冬季温度普遍非常低，所以这个方面是我们首要要重视的一个。再加上这种植物又不太耐寒，所以更得好好注意了。一般来说，周围的温度需要保持在十摄氏度以上，才能保证植株安全度过冬天。要是温度保持到更高，在二十度左右的话，那么可以在中午适当给它通通风。不过，需要注意是晴天的中午。 [图片]2、水分 气温慢慢降低之后，它对水分的需量也在慢慢减少。所以，每天只需稍浇一点点，保持适当的湿就行了。或者也可以通过观察花土的状态来判断是否浇。若是花土干了，那么就浇上一点。在低温的环境，它会处于半休眠甚至完全休眠的状态，代谢速度也慢，所以一定不可以浇太多。还有，给水的时间也需要注意，最好是在中午浇。 [图片]3、肥料 在上一个方面已经说过了，植株 正处在休眠期，需水少，需肥量同样也少。所以，可以不施，也可以适当施一点。不过，浓度得把控好。因为这种植物的根非常细，若是浓度太高很容易影响根部对水分的吸收，长期下去就会导致植株枯掉。还有，盆中也不要放置一些豆饼之类。 4、空气湿度 因为它喜欢湿度较大的生长条件，所以，我们可以每天中午往枝叶上喷点水。 [图片]

Description: This biennial plant is about 1–2½' tall, branching occasionally. The stems have a tendency to zigzag between leaves; they are light green, terete, and both short-pubescent and hairy. The alternate leaves are up to 6" long and 6" across. The lower leaves are pinnately cleft into 5 lobes; they are longer than wide, dentate along their margins, and slightly hairy. The earliest of these lower leaves have patches of greyish white or light green toward the middle of their upper surfaces, providing them with a water-stained appearance. The middle to upper leaves are orbicular and cleft into 5 lobes, resembling maple leaves; they are dentate along their margins and slightly hairy. The petioles of these leaves are rather long and stout; they are both short-pubescent and sparsely hairy. The upper stems terminate in floppy cymes of flowers. These flowers are about ¾" across when they are fully open, becoming more erect while in bloom. Each flower has a lavender or pale purplish pink corolla that consists of 5 spreading petals. At the base of this corolla, there is a hairy green calyx with 5 narrowly triangular teeth. Between each pair of teeth on the calyx, there is a short appendage that is strongly recurved. Toward the center of the corolla, there are 5 stamens with light to medium brown anthers and a slender white style that is divided toward its apex. The peduncles and pedicels of the cymes are light green, terete, and both short-pubescent and hairy; the peduncles are up to 6" long, while the pedicels are up to 1" long. The blooming period occurs from late spring to early summer, lasting about 3 weeks. Each flower is replaced by a 2-chambered capsule containing several seeds. The root system consists of a taproot. This plant spreads by reseeding itself. [图片]Cultivation: The preference is light dappled shade, moist to mesic conditions, and a rich loamy soil containing abundant organic matter. Sometimes this plant succumbs to fusarium wilt and other wilt-causing fungi. In spite of its biennial habit, it is possible to maintain this plant in a woodland flower garden as it reseeds itself readily. Range & Habitat: The native Great Waterleaf occurs occasionally in central and northern Illinois; it is less common or absent in the southern and extreme NW areas of the state (see Distribution Map). Habitats include moist to mesic deciduous woodlands, woodland borders, areas adjacent to woodland paths, shaded or partially shaded seeps, and shaded or partially shaded areas along rivers. This woodland wildflower begins to bloom after the leaves of the trees have partially developed. [图片]Faunal Associations: The nectar and pollen of the flowers attract various kinds of bees, including honeybees, bumblebees, mason bees (Hoplitis spp., Osmia spp.), digger bees (Synhalonia spp.), Andrenid bees (Andrena spp.), and Halictid bees (Lasioglossum spp., etc.). An Andrenid bee, Andrena geranii, is a specialist pollinator (oligolege) of Hydrophyllum spp. Other insects that visit the flowers include Syrphid flies, dance flies (Empis spp.), butterflies, and skippers. Except for these flower visitors, surprisingly little appears to be known about floral-fauna relationships for this species. White-Tailed Deer probably browse on the foliage. Photographic Location: A woodland flower garden on the campus of the University of Illinois in Urbana, Illinois, and a deciduous woodland at Pine Hills State Nature Preserve in west-central Indiana. [图片]Comments: Great Waterleaf (Hydrophyllum appendiculatum) is one of the more common Hydrophyllum spp. within the state and its flowers are the most attractive. This species has hairy stems and calyxes, and some of its leaves resemble maple leaves. A distinctive characteristic consists of the small recurved appendages between the teeth of its calyx, hence the "appendiculatum" in the scientific name. Other Hydrophyllum spp. lack these strongly recurved appendages and they have less showy flowers. Virginia Waterleaf (Hydrophyllum virginiana) and Canada Waterleaf (Hydrophyllum canadense) have less hairy stems, while Large-Leaved Waterleaf (Hydrophyllum macrophyllum) lacks cleft orbicular leaves that resemble maple leaves. The leaves of this latter species are always longer than broad, and they are pinnately divided to an even greater extent than the lower leaves of Great Waterleaf.

Description: This herbaceous perennial plant is about ¾-1' tall and unbranched. A typical plant produces a single basal leaf on a long hairy petiole and a flowering stalk with a pair of cauline leaves near its apex. However, not all plants produce flowers. The central stalk is light green to reddish green, terete, rather stout, and quite hairy. One cauline leaf is sessile, while the other cauline leaf has a short petiole up to 2" long. The petioles of the basal and cauline leaves have characteristics that are similar to the flowering stalk. The basal leaves are up to 10" long and 10" across, while the cauline leaves are up to 8" long and 8" across. Both types of leaves have about 5 palmate lobes and their margins are doubly serrated and shallowly cleft. During the blooming period, these leaves are wrinkled, hairy, and smaller in size, but later in the year they become more smooth, less hairy (or even glabrous), and full-sized. The color of the leaves may change from yellowish green during the spring to medium-dark green during the summer. A flowering plant produces a single terminal flower on a short pedicel (up to 2" long); this pedicel is similar to the central stem in its characteristics. The flower is about ¾" across, consisting of 3 deciduous sepals, no petals, approximately 40 spreading stamens, and approximately 10 clustered pistils in the center. The greenish white sepals drop early and they are not present while the flower is in bloom. The stamens have white filaments and yellow or greenish yellow anthers. The slightly flattened pistils have short beaks and they are initially pale green. The blooming period occurs from mid- to late spring and lasts about 2-3 weeks. By mid- to late summer, the pistils have been replaced by a small tight cluster of bright red berries. Each berry contains 1-2 black shiny seeds. The root system consists of knotty yellow rhizomes and fibrous roots. This plant reproduces by clonal offsets from its rhizomes and by seed. It occasionally forms small colonies. [图片]Cultivation: This plant prefers dappled sunlight during the spring and light to moderate shade during the summer. It prefers moist to mesic conditions and a fertile loamy soil with an abundance of leaf mould. Wild plants are little bothered by disease, although stressed out cultivated plants can be attacked by leaf blight and other diseases. Slugs eat seedlings and the foliage of mature plants, while root knot nematodes occasionally attack the root system. Starting plants from seeds is slow, while vegetative propagation from rhizomes is easier and faster. Range & Habitat: The native Goldenseal occurs occasionally in scattered counties throughout Illinois (see Distribution Map), although populations have been declining because of habitat destruction and over-collection of the rhizomes. Habitats include moist to mesic deciduous woodlands, wooded bluffs, and areas along woodland paths. A limited amount of disturbance is beneficial when it reduces excessive shade from the overhead canopy. [图片]Faunal Associations: The flowers are cross-pollinated by small Halictid bees (Lasioglossum spp.) and masked bees (Hylaeus spp.) primarily; they are also visited by Syrphid flies and larger bees (Sinclair et al., 2000). Presumably birds or small mammals eat the berries and help to distribute the seeds, but little specific information is available about this. Little is known about the attractiveness of the foliage as a food source to mammalian herbivores, although it is probably toxic to them like most members of the Buttercup family. Photographic Location: A deciduous woodland in Vermilion County, Illinois. [图片]Comments: Goldenseal has a unique appearance because of the wrinkled palmate foliage (while young), unusual petal-less flowers, and beaked red fruits. As a result, it is easy to identity at either the flowering or fruiting stage. The biggest threat to this species is over-collection of the rhizomes for herbal medicine; these rhizomes can sell for $100/lb. on the wholesale market. They contain the alkaloids hydrastine, berberine, and canadine. Hydrastine is used for feminine complaints, berberine has anti-bacterial and anti-protozoan properties, and canadine is a sedative and muscle relaxant. Under the CITES convention, it is illegal to export the rhizomes and other parts of rare wild-collected plants in the United States. The common name of this plant refers to the yellow rhizomes.

Description: This shrub is 3-8' tall, producing unbranched canes that are erect. Young tips of the central cane are light green and sometimes pubescent, otherwise the cane is woody with gray to brown bark. With age, this bark tears off into multicolored sheets, providing it with a tattered appearance. Pairs of opposite leaves occur at intervals along each cane. These leaves are about 4-6" long and 3-5" across; they are oval-ovate or oval-cordate and serrated along their margins. The upper surface of each leaf is medium to dark green and hairless, while the lower surface is pale green and either hairless or sparsely pubescent. The slender petioles are 2-6" long and either hairless or pubescent. Each cane terminates in a flat-headed panicle (or compound cyme) of flowers about 3-6" across. In the center of the panicle, there are numerous fertile flowers that are very small in size, while around the outer margin of the panicle there are a few sterile flowers that are larger in size (about ¾" across). However, sterile flowers are occasionally absent in some populations of wild plants. Each fertile flower has a short light green calyx with insignificant teeth, 5 tiny white petals less than 1/8" (3 mm.) long, 8 or 10 stamens with long filaments, and a pistil with a pair of styles. The fertile flowers are either greenish white or cream-colored. Each sterile flower has 3-4 petaloid bracts that are large and white. The branches of the panicle are dull cream-colored and usually pubescent. The blooming period occurs from early to mid-summer. The fertile flowers are in bloomDistribution Map for only a short time, while the sterile flowers remain attractive until the autumn. Each fertile flower is replaced by a small 2-celled seed capsule about 1/8" (3 mm.) across that has a pair of tiny curved horns on its upper surface. The sides of the capsule are ribbed. Each capsule contains many tiny seeds that are flattened; they are small enough to be blown about by the wind or carried by currents of water. The root system can develop clonal offsets from underground runners. As a result, colonies of plants are often formed. Cultivation: The preference is dappled sunlight to light shade, consistently damp conditions, and a moderately acidic to neutral soil that contains some decaying organic matter. To prevent a straggly appearance, this shrub can be cut back during the autumn. A humid area with some protection from the wind is desirable. Range & Habitat: The native Wild Hydrangea is occasional to locally common in southern Illinois, uncommon in central Illinois, and largely absent from the northern section of the state. Habitats include shaded ravines, rocky stream banks in wooded areas, bottoms of bluffs and cliffs, low rocky ledges, and similar habitats in wooded areas. Wild Hydrangea is found in high quality natural areas. It is also cultivated in gardens. Faunal Associations: The fertile flowers offer nectar and pollen to a wide range of visiting insects. These visitors include bumblebees, little carpenter bees (Ceratina spp.), Halictid bees, masked bees (Hylaeus spp.), miscellaneous wasps, mosquitoes, Syrphid flies, thick-headed flies, Muscid flies, dance flies (Empis spp.), tumbling flower beetles, and long-horned beetles. The foliage of Wild Hydrangea is eaten by the caterpillars of Darapsa versicolor (Hydrangea Sphinx) and Olethreutes ferriferana (Hydrangea Leaf-Tier Moth). Some polyphagous insects occasionally feed on this shrub; these species include the thrips Echinothrips americanus, the seed bug Kleidocerys resedae, the aphids Aphis rumicis and Aphis citricola, and the larvae of the long-horned beetle Stenocorus cinnamopterus. White-tailed Deer occasionally browse on the canes and leaves. Photographic Location: The flowerhead was photographed at the Arboretum of the University of Illinois in Urbana, Illinois. The leaves were photographed at the Potholes in west-central Indiana. [图片]Comments: This fast-growing shrub is very attractive. The only other native hydrangea in Illinois is Hydrangea cinerea (Southern Wild Hydrangea), which is found in the southern section of the state. This latter species differs from Wild Hydrangea by the dense gray pubescence on the undersides of its leaves; it is sometimes considered a variety of Wild Hydrangea, rather than a distinct species. There are many cultivars of Wild Hydrangea in circulation. These cultivars tend to have more sterile flowers than the wild version of this species; there are even cultivars that produce only sterile flowers. While the latter cultivars are showier, they don't provide any nectar or pollen to flower-visiting insects. From an ecological perspective, this makes them less desirable.

Description: This perennial wildflower is 1½–3' tall and usually unbranched. The central stem is hairy. The alternate leaves are up to 6" long and 1½" across; they are medium to dark green and elliptic in shape. The leaf margins are smooth and ciliate; on rare occasions, a few teeth may occur along the outer margins. Each leaf tapers gradually to a wedge-shaped base and a short petiole. The upper and lower surfaces of each leaf are hairless to somewhat hairy. At the upper axil of each leaf, there are 1-3 small nodding flowers that are light green. Each flower is about ¼" long, consisting of 5 linear sepals, 5 oblong petals, 5 stamens, and a pistil. The pedicel of each flower is about ½" long and hairy. Near the base of each pedicel, there is a pair of linear stipules (leafy bracts) up to ¼" long. Terminal flowers are not produced. The blooming period occurs from mid-spring to early summer and lasts about 1–1½ months. There is no noticeable floral scent. Each fertile flower is replaced by a seed capsule about ½–¾" long. The seed capsules are light green, ovoid-oblongoid in shape, and hairless. At maturity, each capsule splits into 3 sections to release the seeds. The root system is is fibrous and rhizomatous. Clonal colonies of plants are occasionally formed from the rhizomes. Cultivation: The preference is dappled sunlight to medium shade, moist to mesic conditions, and a rich loamy soil with abundant organic matter (e.g., fallen leaves). Some rocky material (e.g., limestone) is also tolerated. The pH of the soil should be mildly acid, neutral, or basic. [图片]Range & Habitat: The native Green Violet is occasional in most areas of Illinois, except in the NW section, where it is absent (see Distribution Map). Overall, it is more common in hilly areas of southern Illinois than in the glaciated areas of northern Illinois. Habitats include moist to mesic deciduous woodlands, wooded slopes, shaded terraces along streams, and damp ravines, particularly where calcareous rocky material is close to the surface of the ground. This species is fairly conservative and normally found in high quality woodlands where the original ground flora is still intact. Faunal Associations: Very little is known about floral-faunal relationships for this species. Robertson observed a green metallic bee, Augochlorella striata, sucking nectar from the flowers; however, insect visitors to the non-showy flowers are uncommon. The polyphagous insect, Acrosternum hilaris (Green Stink Bug; a.k.a. Chinavia hilare) sucks juices from the foliage. White-Tailed Deer often chomp off the tops of this plant. It is possible that upland gamebirds and the White-Footed Mouse feed on the seeds, which are rather large in size. [图片]Photographic Location: A shaded ravine in Vermilion County, Illinois. Comments: This atypical member of the Violet family is primarily a foliage plant; the small flowers are largely hidden by the leaves and non-showy. The seed capsules of Green Violet are very similar in appearance to those of other violets (Viola spp.), although they are somewhat larger in size; the seed capsules of both the Green Violet and other violets divide into 3 longitudinal sections to release their seeds. There is also some similarity in the structure of their respective flowers. Looking at this plant, most people would never guess that it is a violet.

Description: This herbaceous perennial plant consists of a large tuft of basal leaves up to ½' tall, from which one or more flowering stalks develop that are 2–3½' tall. The blades of the basal leaves are 2½–4" across. They are more or less orbicular in overall shape, but with 5-9 lobes along their margins; these lobes are shallow and rounded. The blades are indented at the junction of the petioles, while their margins are coarsely crenate-dentate. The upper surfaces of the leaf blades are medium green and sometimes variegated; they have scattered short hairs and a rough texture. The slender petioles are light green and hairy; they are as long or longer than their blades. The tall flowering stalks are light green, terete, hairy, and without leaves. At the apex of each stalk, there is a narrow panicle of flowers about 3-8" long. The spreading branches of the panicle are light green and hairy, while the flowers are drooping. Each fully developed flower is 4.0–4.5 mm. long, consisting of a light green or reddish green calyx with 5 narrow lobes, 5 light green petals, 5 strongly exerted stamens with orange-red anthers, and 2 styles. The petals are smaller than the calyx and insignificant. The calyx is conspicuously swollen toward its base. The blooming period occurs from late spring to early summer and lasts about 3 weeks. There is no noticeable floral scent. Each flower is replaced by a small seed capsule that has 2 prominent beaks. There are numerous tiny seeds inside each capsule, which are small enough to be blown about by the wind. The root system consists of a crown with fibrous roots. The preceding description applies only to var. hirsuticaulis. Cultivation: The preference is dappled sunlight during the spring, followed by light shade during the summer. The soil should be well-drained, mesic to dry, and loamy or rocky. This is primarily a foliage plant that can function as a ground cover if it is densely planted. Range & Habitat: The native Woodland Alumroot is occasional in the southern half of Illinois, while in the northern half of the state it is rare or absent (see Distribution Map). Habitats include upland rocky woodlands, thinly wooded bluffs, and wooded slopes. This species is found in high quality habitats where oak trees are often present. The most commonly encountered variety of Woodland Alumroot within the state is var. hirsuticaulis. Faunal Associations: The nectar and pollen of the flowers attract small bees, including Halictid bees (Halictus spp., Lasioglossum spp., & Augochlorella spp.) and the oligolectic Plasterer bee Colletes aestivalis. This latter bee is a specialist pollinator of Heuchera spp. Insects that prefer to feed on the foliage or juices of Heuchera spp. include the flea beetle Altica heucherae and the aphid Nasonovia heucherae. The bitter-tasting basal leaves are usually ignored by mammalian herbivores. [图片]Photographic Location: An upland rocky woodland at the Portland Arch in west-central Indiana. Comments: Woodland Alumroot and other native Heuchera spp. are related to the commonly cultivated 'Coral Bells' of horticulture. However, the flowers of the native species are usually green and less showy. Across its range, different varieties of Woodland Alumroot have been identified. Compared to the typical variety, the variety that has been described here (var. hirsuticaulis) has flowering stalks and petioles that are more hairy. Otherwise, they are very similar. Another variety that has been recognized in Illinois, var. interior, has smaller flowers (3.0–3.5 mm. long) than var. hirsuticaulis. Another species in this genus that is sometimes encountered within the state is Heuchera richardsonii (Prairie Alumroot). It differs from the preceding varieties of Woodland Alumroot by its longer asymmetrical flowers (5.0–9.0 mm.). The flowers of Woodland Alumroot are more symmetrical (one side of the flower is about as long as another side).
