Abstract
Poinsettia `441` is a stiff-stemmed, early flowering cultivar with dark red flower bracts. It has dark green, medium size foliage and a strong branching habit. The plant height is medium and some chemical growth retardants may be needed to control the height of flowering plants. The appearance and cultural requirements are very similar to Poinsettia `Lilo` (U.S. Plant Pat. No. 6,694). However, stronger self-branching traits and better post-production keeping qualities make `441` a more desirable commercial cultivar than `Lilo`.
