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。
