Due to the 58th Presidential Inauguration, the U.S. Botanic Garden will be closed January 18-21, 2017. We will reopen at 10 a.m. on January 22.
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.
