Euphorbia x martini 'Ascot Rainbow' is an eye-catching variegated spurge that brings year-round interest to the garden with its striking foliage and unique flowers. This compact, upright perennial is prized for its gray-green leaves edged in golden-yellow, often flushed with pink or red tones during cooler weather.
