补充资料:垂丝海棠的形态特征
垂丝海棠又名锦带花,属蔷薇科,苹果属,为落叶灌木或小乔木。原产我国华东、中南、西南,以四川为最多。此花树姿婆婆,花粉红色,花梗细长,紫红色,下垂成带状,花4-7朵聚生为一簇,形似樱花,花瓣5枚以上,朵朵弯垂,迎风轻荡,色艳韵美,绰约动人。常见的垂丝海棠有两种,一为重瓣垂丝海棠,花为重瓣;一为白花垂丝海棠,花近白色,小而梗短。垂丝海棠性喜阳光,不耐阴,也不甚耐寒,爱温暖湿润环境,适生于阳光充足、背风之处,土壤要求不严,微酸或微碱性土壤均可成长,但以土层深厚、疏松、肥沃、排水良好略带粘质的生长更好。此花生性强健,栽培容易,不需要特殊技术管理,唯不耐水涝,盆栽须防止水渍,以免烂根。
