盾叶天竺葵(P.peltatum),又称蔓性天竺葵,是牻牛儿苗科天竺葵属多年生蔓生常绿草本。因花蕾呈穗状圆球形,酷似葡萄,在北方部分地区又称葡萄海棠。其叶盾形,肉质光亮,全缘;茎光滑细弱,呈黑褐色;花色有粉、白、红、紫等,除7～8月高温季节休眠外,全年有近10个月的花期,是南北各地的盆栽花卉珍品。一、生物学特性天竺葵类植物原产于非洲南部,喜阳光充足,耐干燥,忌水湿,要求排水良好、富含有机质的土壤。高温35℃时进入半休眠状态,低温3℃以下易受寒害。越夏期间需在荫蔽、通风、凉爽处养护,尽量避免积水受涝。冬季在10℃以上室温下生长较好,不受任何损害。
Pteridium pelargonium (P.peltatum), also known as creeping geranium, is a geranium geranium geranium gentian perennial evergreen herb. Because of buds spike-shaped ball, resembles grapes, also known as Grape Begonia in some parts of the north. Its leaves are shield-shaped, fleshy and bright; the stems are smooth and delicate, with a dark brown color; and the colors are pink, white, red and purple. Except for the high-temperature seasons during July and August, there are nearly 10 months of flowering, Potted flower treasures all over the north and south. First, the biological characteristics of Geranium plants native to southern Africa, hi sunny enough, resistant to dry, avoid water wet, require good drainage, organic-rich soil. High temperature into the semi-dormant 35 ℃, low temperature below 3 ℃ susceptible to cold damage. During the summer, shaded, ventilated and cool areas should be conserved to avoid waterlogging. Winter at 10 ℃ above room temperature growth is better, without any damage.
