Pendent yellow catkins are borne in late winter and early spring. Strongly twisted, spiraling shoots provide year-round interest. Noteworthy Characteristics: Excellent specimen tree. Use shoots in floral arrangements. If possible, purchase trees grown on their own roots to avoid rootstock suckers. A newer cultivar, 'Red Majestic', bears burgundy colored new growth, so it has greater summer appeal. Care: Grow in fertile, well-drained soil in sun or partial shade. Ideal for alkaline soils. Prune out unwanted suckers, which can be abundant. Propagation: Layer in autumn; graft in winter. Problems: Powdery mildew, blight, canker, dieback, mushroom root rot, fungal spots, Gymnosporangium rust, bud mites, tent caterpillars, and webworms. Overview Height 10 ft. to 15 ft.
