蔓长春花属夹竹桃科蔓长春花属,引自欧洲。株高20厘米,常绿蔓生半灌木,丛生。叶深绿色,长3～5厘米,对生,椭圆形,有光泽。花淡紫色或红色,管状,单生于开花枝叶腋内,花期3～5月。根据花色的不同可分为紫蔓、红蔓两种。蔓茎生长不长,作地被时茎节处发根,形成致密的地被。开花枝直立,高30厘米,可作花境、园路边缘绿化。耐寒性强,-20℃低温环境中也能绿叶挺立,冬日里能绿意盎然。栽培方式按40厘米蔓长计,每平方米9～11株,在20℃左右70～80天就能形成致密地被。蔓长春花的生产管理与其所需环境是分不开的,而影响其生长的环境因子主要
Vanda vinca Oleaceae vinca, quoted from Europe. Plant height of 20 cm, evergreen vines and shrubs, clusters. Dark green leaves, 3 to 5 cm long, opposite, oval, shiny. Flowers lavender or red, tubular, solitary in the axillary flowering branches and leaves, flowering 3 to May. According to the different colors can be divided into purple vine, red vine two.
