Ascot Rainbow Euphorbia
Initially introduced in 2010, this new variety is really catching on. This has to be one of my favorite new perennials. It is one of the cushion spurges. Some report that it has overwintered well in zone five. However, most sources consider it to be reliably hardy to zone seven or so.
Ascot Rainbow is over 1½ feet tall. This bushy, lush, vigorous plant is named for the rainbow of colors displayed on the foliage. The older leaves are green with wide bands of yellow along the edges.
