落地生根（学名：Bryophyllum pinnatum），又称叶生、天灯笼、大还魂、倒地莲、倒吊莲、打不死，原产地为非洲。由于若将其叶放在泥土中，叶边的一点即能发芽生长，不必依赖种子繁殖，故名落地生根。若将它屈折或打断，其叶着地即能生长，故亦有打不死之名。具有止血、消炎、止痛、消肿解毒之功效。但脾胃虚寒者慎服。此外也可做切花、盆栽、花坛和庭园露地栽培。

别名：因为花的形状好像许多灯笼倒吊着，所以在民间也叫做灯笼花、吊钟花等名称，落地生根是民间常用的药用植物，生性耐建，和景天科其他著名植物如长春花、石莲花都有极强的生命力，因此有长寿与坚忍的代表寓意。

Bryophyllum pinnatum, also known as the air plant, cathedral bells, life plant, miracle leaf, and Goethe plant is a succulent plant native to Madagascar, which is a popular houseplant and has become naturalized in tropical and subtropical areas. It is distinctive for the profusion of miniature plantlets that form on the margins of its phylloclades, a trait it has in common with some other members of its genus.
