Topwhite poinsettia

Plant Botanical Name: 
Euphorbia pulcherrima 'Topwhite'

Patented in 1982 by the Paul Ecke Ranch, 'Topwhite' was a radiation-induced sport of the 'Annette Hegg' poinsettia. Its very white bract color, combined with the 'Annette Hegg' growing habit and ease of production was its selling point.
