These relatively tough and carefree 2- to 5-foot-tall, deciduous shrubs look great all year. They have bright golden-yellow flowers for 1 week in spring and graceful foliage in summer, and are yellow with light green, twiggy branches in winter. A few flowers bloom in summer and fall. Plant in masses in shrub borders, woodland and wild gardens. Varieties are available with single flowers and white-variegated leaves. Drought-tolerant once established, they do best in partial shade but tolerate full sun in cool climates. Cut branches in winter are excellent in flower arrangements. Remove old shoots and branches to shape. Overfertilization causes excessive growth and few flowers.
