No cultivar name of record
This patent does not name the plant. Through the 1980s and early 1990s that was still common: naming every new cultivar only became standard practice as plants began to be marketed under brand names. The grant identifies this one by its number and by a written description instead.
Nothing here is missing from our records: the patent itself states no name. Where one exists we show it, and we do not invent one.
Abstract
Poinsettia `529` is an early flowering cultivar with dark red flower bracts. It has dark green, medium size foliage, stiff stems and a strong branching habit. Cultivar `529` has traits which differ from `Lilo` (U.S. Plant Pat. No. 6,694) and make `529` a more desirable plant for commercial pot plant production. Namely, cultivar `529` is earlier flowering, shorter, stiffer stemmed, freer branching, with brighter red bracts and improved post-production keeping qualities compared to `Lilo`. It is also less prone to "splitting".
