Abstract
Poinsettia, cultivar `456` is an induced by mutation cultivar, `H518` (U.S. Plant Pat. No. 6,150) with dark red flower bracts and dark green foliage. It branches more freely than `H518`, but retains the same desirable flower and foliage characteristics. The plant height of `456` is somewhat shorter than that of `H518`. The relative shortness of `456` offers certain economic advantages over `H518`, in that, less growth retarding chemicals need to be used to control plant height.
