Charming, one inch wide, bright yellow flowers appear in late spring and continue through early summer, perhaps later if deadheaded. The finely cut, feathery foliage forms a tight, symmetrical mound that is attractive even when the plant is not in bloom. Use it for mass planting or in containers. Drought tolerant.
