A mound of bright white flowers opens March through May on short stems above a dwarf, dark green mound of foliage. It's a veritable snowball, 3" T x 4" W, and very cute. Shield it from the hot sun and give it well-drained soil, a gritty compost dressed with a little limestone. A shallow container with just enough water and plenty of air circulation will keep it thrifty.
Minimum temperature: -30° F
