Abstract: 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.
