补充资料：紫薇的形态特征
紫薇又名满堂红、百日红、怕痒树，是千屈菜科，紫薇属落木或小乔木。原产我国中南部长江流域诸省。其树干灰绿色、光滑，有明显片状剥落，枝干多扭曲，幼枝赂呈四棱形。叶卵圆形，单叶互生，绿色，叶柄极短。花顶生，有紫红、粉红和白色，一枝可开50一60朵花，花期6-9月，开谢相继，可延续100天左右，故又名“百日红”。花后结果，果椭圆形，种子有翅。常见品种有：紫薇，花紫红色；银额，花白色；翠薇，花紫，略带蓝色。此树树干若用手去轻轻抚摸，则全树树干会颤动，好似有知觉的动物，故又得名“怕痒树”。
紫薇因其花色多样、鲜艳，盛开时正值缺花季节，花期又长，且生长快，繁殖容易，树性强健，寿命也长，一二百年的老树仍健壮生长，花开满树，灿若红霞，故而很得爱花者器重，为建筑物前及庭院内上佳的观赏花木之一。紫薇叶细、枝密、干粗、根露，且枝条柔软，易于绑扎，它的老根蔸经人工修剪缚扎后，可培育成苍劲古朴、盘根错节、虬枝屈曲的树桩盆景，具有很高的观赏价值。
紫薇能吸收二氧化硫、氯化氢、氟化氢等有害气体，净化空气，它是城市绿化、保护环境的理想花木。紫薇还具有吸滞粉尘的能力，据测定，距污染源200-250米远，每平方米叶片可吸滞粉尘4.42克，故紫被对大气污染地区具有保护环境的作用。
