红花深山含笑是2007年发现并快速繁殖应用的木兰科种类。本文在野外调查的基础上，结合文献资料，对红花深山含笑的发现历程、形态性状变异、繁殖推广应用现状进行分析。结果表明，红花深山含笑是优良的乡土树种，发现时野外数量极少；实生苗间存在一定的性状差异，是资源开发的优良种质资源；目前红花深山含笑繁殖主要以嫁接为主，通过正确的嫁接方法及良好的后期管理可有效繁殖苗木。

Michelia maudiae var. rubicunda is a new variety of Magnoliaceae that has been rapidly applied in landscape since discovered in 2007. On the basis of literature review and field investigation, this paper analyzed the discovery history, character variation, propagation technology and application of M. maudiae var. rubicunda. The results showed that it was a native tree species, but few distributed in wild. Character segregation could be easily appeared among the seedlings thus provide valuable resources for development of its germplasm. The current breeding of this variety is mostly through grafting. The right grafting methods and the cultivation management can effectively obtain enough seedlings.
