Folks who have trialed Euphorbia 'Ascot Rainbow' have been most impressed, especially after it survived a harsh south Michigan winter. Euphorbia x martinii 'Ascot Rainbow' (Euphorbia characias x Euphorbia amygdaloides 'Rubra') was discovered by David Glenn in Australia, but was granted permanent garden worker status in the US. The 20" tall, branching, evergreen stalks are adorned with narrow, glaucous leaves, each edged in an attractive yellow border. In cold weather, the upper leaves take on an attractive red overlay, then in early spring the deer-resistant clumps are topped with bouffant-like flower clusters consisting of showy green- and yellow-striped bracts, housing the tiny red flowers...simply stunning!
