Description: This perennial plant is ½–1' tall and unbranched. The foliage consists primarily of basal leaves up to 6" long and 2" across, which are arranged as a rosette. From the center of this rosette, emerges a stout flowering stalk, which is often covered with long white hairs. The stalk itself may be green or reddish brown. There are a few small leaves that alternate along this stem. The leaves are lanceolate or oblanceolate, with angular pinnate lobes and crenate margins. The margins have a tendency to undulate vertically. These characteristics provide the leaves with an almost fern-like appearance, except they are somewhat heavier and thicker. The flowers occur along a spike at the top of the stem. They are about ¾" long and tubular with two lips. The upper lip curves downward and functions as a protective hood, while the lower lip functions as a landing pad for insects. The flowers are usually yellow, but sometimes brownish red. The lower lip of the flower is often white. These flowers bloom from the bottom up during late spring; this blooming period lasts about 3 weeks. There is a mild floral fragrance that is not always detectable to the human nose, although bees and other insects can detect it. The flowers are replaced by large fruits that are angular and hairy. The root system consists of a taproot, and lateral roots that are parasitic on the roots of grasses and possibly other plants. Wood Betony, however, is capable of normal growth and development even when suitable host plants are unavailable. This plant often forms colonies by reseeding itself. Cultivation: The preference is partial to full sun, mesic to dry conditions, and a somewhat acidic soil, which can be loamy or sandy. Most of the growth and development of this plant occurs during the spring, although the leaves stay green during the summer. [图片]Range & Habitat: The native Woody Betony occurs occasionally in the northern half of Illinois, but it is uncommon or absent in the southern half of Illinois (see Distribution Map). Habitats include mesic to dry black soil prairies, open woodlands and sandy woodlands, savannas and sandy savannas, thickets, and borders of lakes. This plant is often associated with the Black Oak in woodlands and savannas. Because of its parasitic habit, there is a tendency for the surrounding grass to be shorter in height than it would be normally, creating open areas along the ground where colonies of Wood Betony occur. Faunal Associations: Long-tongued bees are the primary visitors of the flowers, including queen bumblebees and Mason bees. Occasionally, short-tongued Halictid bees may visit the flowers to collect pollen, but they are non-pollinating. Little information is available about this plant's relationship to birds and mammalian herbivores. [图片]Photographic Location: The photographs were taken at a meadow of Orchid Hill in Vermilion County, Illinois, the Prospect Cemetery Prairie in Ford County, Illinois, and a rocky woodland of the Potholes in west-central Indiana. Comments: Wood Betony is very showy when it is in full bloom. Because of the unusual flowers and foliage, it has a striking appearance. There are other Pedicularis spp. that this plant resembles, however most of them don't occur in Illinois. An exception is Pedicularis lanceolata (Swamp Betony), which differs from Wood Betony by its greater height, leaves with shallower pinnate lobes, and preference for wetland habitats. The flowers of these two plants are very similar. Another common name for this plant is Lousewort, which was based on the mistaken belief that it could repel lice and similar parasites from livestock.

Description: This perennial plant is about 2-3' tall while in flower. There is a rosette of basal leaves up to 6" long and 4" wide on long petioles. They are medium green, sandpapery in texture, coarsely serrated along the margins, and broadly lanceolate, ovate, or cordate. From the middle of this rosette, a stout flowering stalk develops, which has smaller alternate leaves on short petioles. Usually there are erect side stems that each develop an inflorescence. An inflorescence consists of flat-headed clusters of small white flowerheads; usually, there are several of them bunched loosely together on the same plant. Each flowerhead is about 1/3" (8 mm.) across, consisting primarily of numerous disk florets, while the few ray florets are greatly reduced in size and barely perceptible. The overall effect is similar to a head of cauliflower. The blooming period occurs from late spring to mid-summer, and lasts about 2 months. There is no noticeable floral scent. Eventually, the flowerheads turn brown, and the achenes develop without tufts of hair. The central taproot is quite thickened and somewhat tuberous in appearance, while rhizomes promote the vegetative spread of this plant. Cultivation: The preference is full sun and mesic conditions. However, a small amount of shade is tolerated, and the soil can vary from moist to slightly dry. A fertile loamy soil is preferred, although the presence of some sand or rocky material is tolerated. While established plants are fairly easy to grow, recent transplants can be temperamental. It is important to put the transplants into the ground after danger of hard frost has passed, but before the period of active growth occurs during the late spring and early summer. Foliar disease isn't a significant problem. During a drought, some of the lower leaves may turn yellow and wither away. Range & Habitat: The native Wild Quinine occurs occasionally in the majority of counties in Illinois, however it is uncommon or absent in many areas of western and SE Illinois (see Distribution Map). In high quality habitats, Wild Quinine can be locally common, while in disturbed areas it is uncommon, possibly because of the limited dispersion of its seeds. Habitats include mesic black soil prairies, sand prairies, openings in rocky upland forests, savannas, scrubby barrens, limestone glades, and thickets. [图片]Faunal Associations: The flowers attract Halictine bees, wasps, flies, beetles, and plant bugs. The beetles usually feed on pollen, while the other insects seek nectar primarily. The fly visitors include Syrphid flies, Tachinid flies, Flesh flies, Muscid flies, Anthomyiid flies, and others. Wasp visitors include Crabronine wasps, Eumenine wasps, Cuckoo wasps, Braconid wasps, and others. Mammalian herbivores appear to ignore this plant as a food source because the leaves are sandpapery in texture and bitter-tasting. Photographic Location: The photographs were taken at a remnant prairie along an abandoned railroad in Champaign County, Illinois, and the webmaster's wildflower garden in Urbana, Illinois. [图片]Comments: Don't be put off by the lack of conspicuous ray florets on the flowerheads – they are still quite showy, resembling small white pearls from a distance. The leaves are admittedly rather coarse, but they possess characteristics that help this plant to survive in the prairie (as well as one's flower garden). Because of the unique flowerheads, this plant can be confused with no other species in Illinois; there are some close relatives that occur in other states, however. Wild Quinine was used as a substitute for the bark of the Cinchona tree during World War I, when the supply of the latter was disrupted; this was an attempt to maintain the supply of quinine to treat malaria.

[图片]一、播种 银边翠的播种时节是每年的春季。北方人民一般将它种于花盆。将加了花肥的花土放在盆中,均匀的撒上种子,再附上一层花土。之后浇上适量的水,再在花盆上面覆上一层塑料膜,从而为植物提供一个温暖、潮湿的环境。最好将温度保持在二十度左右,也可将盆栽放在室内的阳台上。因为植物拥有了适宜的生长环境,种植人可坐等植物开花,时常约为七到十天。 具体的播种数量:可将种子按照三乘以三厘米的距离进行播种,种子无需播撒过多,适量就好。播后可用喷雾器把花土表面喷湿,当盆土略干时再喷水。 播种后的管理:在秋季播种后,要适时的对植物进行调整,温度较低时,将塑料膜盖严,温度上升较高时则要注意防止阳光灼伤幼芽,适当的将塑料膜开启一个小缝,这样才能保证种芽更好的生长。 [图片]二、扦插 扦插不同于自然播种。扦插的植物必须是生长旺盛的嫩枝。具体操作:预留十五公分长的嫩枝干,将伤口剪成尖状,插在花土中。深度不宜过深。切记,前四天不可浇水,否则导致枝干泡在水中,易腐败,不利于枝干的生根发芽。除此方法,还可以将枝干的伤口蘸满草木灰,随后插在花土中。两星期后即可生根发芽。 [图片]后续养护管理: 温度:温度严重影响植物的生根,温度过低,插穗难生根,冬季时可以将植株放到温暖的位置养护。温度过高,夏季插穗易腐烂,措施主要是遮荫,要遮去一半阳光,同时,用喷雾器每天喷几次,温度高则多喷,温度低,则少喷。 湿度:扦插后将室内湿度在保持在百分之五十以上。可以通过喷雾器来增加湿度,每天三次。切记,过度地喷,插穗容易腐烂。 [图片]

[图片]土壤的选择 培植土的选择是种花过程中非常重要的易患,倘若选对了培植土,它们往往能开的非常茂盛,但是若是选择选错了,有时候连花都开不出来。这就要求我们按照花朵的偏好来为它选择培植土。 种植它的培植土需要有充足的营养,也就是说我们在选择培养土时要尽可能选肥力高的。这样的土能够供给幼株更多的营养满足它生长发育的需求。 其次,要尽量选择疏松的培植土。 一是因为这样的培植土利于氧气的供给。不管是种子的出芽还是根系的发育,都离不开氧气,选择疏松的培植土可以更利于花朵生长。 二是因为疏松的培植土利于土中水分的保持。 锦带花喜湿,能够保湿的培植土可以给它一个舒适的“家”,帮助它生长得更好。 [图片]种子的收集与处理 锦带花的果子一般在9~10月份成熟,这就是我们采集种子的时候了。将种子刚从枝干上采下,置于阴处晾干。用工具将它碾碎再进行风选,之后就能得到优质的种子了。 在下种前一周,需要对种子进行催芽,增加种子的出芽率。 播种方法 选择一个大小合适的花盆,将准备好的培植土放入其中,注意不能放得太满,八分满即可。 将经过催芽的种子均匀的撒在土表,要注意种子之间的距离保持适中,不能太小也不能太大。 如果种距过大,会导致长成的花朵距离过大,显得非常零散、不好看。若是距离太小会导致花朵之间没有足够的空间,生长资源不足,长势较差。 用一层厚度适中的培植土盖在种子上,令种子没入土中。 最后在往花盆中浇一些水,保证培植土湿润。 种子的发芽时间因具体的情况不同而不同,但只要打理得当,约20天左右新苗就会出土啦。 [图片]

[图片]一.扦插方法: 1.扦插枝条的选择与处理。枝条选择最简单,直接在现有的成熟植株上剪下一枝即可。剪切口处往上五厘米内的多余叶子要摘掉只余两片。之后将枝条放在干净通风的位置自然晾干三天。晾干后再将花枝切口处浸入生根液,这样可以保证生根速度增加存活几率,要注意一根枝条只要浸泡一次,过多则适得其反抑制生长。 2.花盘及土壤的选择。因为长寿花是气生根,对透气性和排水性都有要求。所以花盆最好选择透气性好的底部带排水孔的粘土盆,土壤可以选择沙土或者直接在花店购买排水好的土壤。 [图片]3.前期种植与保湿。直接将枝条插入土壤中,顶部露出,固定好后浇透水。保湿有一个简单便捷的方法:拿一个尺寸足够完全覆盖花盆的透明塑料袋,顶部剪几个口子以透气,之后套在盆上直到两至三周后开始生根。 4.后期浇水与保温。长寿花喜温怕寒,冬季寒冷,最好放在温度十五度左右的室内通风并且阳光充足的地方。当土壤干燥时浇水,大约一周一次,在前两三周浇水后不要忘了再将塑料袋套上,浇水时要浇透至排水孔有水漏出,注意如果有底部托盘就要将底部托盘的水倒净再放回盆底,否则容易根烂。 [图片]二.养护事项: 1.摘心与打顶。对于长寿花来说,生长期长得太高太长不利于后期开花繁密,所以一定要及时摘心与打顶以多分侧枝。当其长到五对叶子的时候要摘中间三对只留两对,之后等侧芽再长出五对时重复操作,约需摘心两、三次;对于过长或者分侧枝过少的枝条要将上部直接剪掉只留底部两对叶片。 2.施肥。施磷钾肥有助于花苞繁密并且延长花期,按生长情况半月或者一月一施都可以。生长期适当施氮肥也有助于生长。 3.病虫害防治。白粉病是长寿花的最常见病害,可喷专用的杀菌药预防,频率大概每月一次,喷时注意叶子背面也要顾及。 [图片]

[图片]土壤的选择 多花野牡丹习惯生长在略微呈碱性的基质之上。所以在为其挑选基质时,可以选择PH在7.0~8.0之间的培植土。 作为牡丹花的一种,它也与其它牡丹花一样比较喜肥,所以在为其挑选基质时,可以选择肥力相对较大的培植土。 种子的发芽需要氧气供给呼吸,它的种子也不例外。所以在为其挑选基质时,可以选择土质相对疏松通气的培植土。 它比较怕积水,一来由于积水有可能会淹没它的种子,导致种子无法接触空气,不能发芽,二来是由于它的根不能长期泡在水中,否则会引起腐烂。所以在为其挑选基质时,可以选择不会积水的培植土。 [图片]温度的调节 它和其它的牡丹花一样喜欢温暖的生长环境,种植温度最好保持在20℃左右。 在室外种植的话还要考虑室外的温度适不适合它的生长,如果处于正处于严冬或是酷夏,可以先将种子贮藏,等到温度适宜的时候再开始下种。 种植的方法 首先挑选尺寸合适的花盆,消毒后开始装培植土, 在培植土中可以混入一些腐叶,不但可以增加基质的通气能力,而且可以提供一定的养分供植株吸收。 基质不能装的太满,否则会影响后面的浇水工作。 用工具将土面处理平整,再开始撒种。撒种时还需要考虑种子的分布问题,只有让种子平均的分布在基质上,才能够让长出来的盆栽有足够的观赏性。 撒完种后不要忘记在种子上覆盖上一层培植土,保证种子完全没入土中,使它能正常出芽。 最后还需要使用花洒将花盆里的基质浇湿,为种子提供一个湿润的发芽环境,以利于它出芽。 [图片]

如果是做盆景雅乐之舞绝对是佳品,因为其容易造型,也正因为这样,所以不少花友都想养一盆,那么多肉雅乐之舞怎么繁殖呢?其实很简单,就是我们常用的扦插法就可以了。 [图片]雅乐之舞扦插,一般在生长季节进行,扦条可用整形时修剪下来的枝条,扦插长短要求不严,差不多就可以了,要潮土干插,插后适当介质保持潮气,也就是那种不干但是有点潮潮的感觉,如果温度合适一般2~3周就可以生根了。 对于生根时间这里要特别说一下,很多花友都反应说自己扦插的雅乐之舞好久了也不生根,也不烂,其实这种情况,多半是扦插时间不对,建议花友在生长季扦插, 不要在冬季扦插。扦插后放置在散光的环境下养护即可。 雅乐之舞日常养护,除夏季高温时稍加遮荫外,其他季节都要尽量多接受阳光的照射。夏季应加强通风,避免闷热潮湿的环境,否则会因根部腐烂引起落叶。 春、秋季节的生长旺季,每半个月施一次腐熟的稀薄液肥或复合肥,注意肥水中的氮肥含量不可过多,以免叶片中带有过多的绿色,不能突出品种特色。平时浇水掌握“干透浇透”,避免盆土长期积水。 冬季保持盆土干燥,5℃左右即可安全越冬。由于本种生长较快,要经常修剪整形,去掉多余的枝条,以保持株形的优美。 根据生长情况,每年春季翻盆一次,盆土要求疏松、肥沃,并有良好的排水、透气性。常用腐叶土2份,粗沙、蛭石或珍珠岩2份,园土1份,并掺入少量的草木灰或骨粉作基肥,混匀后使用。

[图片]一、叶插 很多花啊草啊的都可以用这种方法,这种方法也不难学。我们首先选一个长得老得,比较壮的叶子,小心地摘下来,放在通风干燥的地方晾上几天,要等到他的叶子下边的伤口变干为止。变干了,我们就可以开始插了。找一盆肥沃的土,土一定要松一些,透气好的那种,斜斜的插下去,或者平着放入土中也可以,下面一定要和土壤结合得十分紧,插玩以后,拿水壶喷一些水,就可以放到阴凉的地方了,等待它发芽。这段时间里盆里的土要保持半干不干,温度也要合理,别晒太阳,被晒脱水就完了。这样精心呵护下来,几天就能发芽长出根了。 [图片]二、分株 这也是很常用的方法,而且最后长成的可能性还是很大的。分株的时候可以在翻盆的时候顺便进行。给肉肉翻盆的时候,直接把老的植株旁边的新长出来的小苗拿下来,如果有根那就最好,直接栽到盆里大概率能活,没根的也不要担心,拿去晾几天,然后再来栽,也可以活。这样栽完以后,浇一浇,放在比较温和的地方,别照太多阳光,过一段时间就可以看到它长得很好了,新的芽新的叶全长了出来。 [图片]三、播种 我们的小肉肉还会结种子呢!每次等到它结种子了,等到种子成熟了就赶紧得去收起来,因为保存的时间不长,时间长了会好多就发不了芽了,所以最好随时收随时种。选好优质的土,弄的湿一点,种下去,等发了芽,长出的小苗要仔细照看。
