Prefers consistent and regular moisture in well-drained acidic, loamy, organically-enriched soils in full sun to partial shade. It tolerates pollution and needs a protected site from late frosts.

Has a fleshy root system that requires plenty of room. flowers at early age and appear in late winter before leaves, and has a medium-to-course texture. Fruit ripens in the fall and is not ornamental. It is subject to flower killing by late frosts. Winter pubescent flower buds appear as having just received a haircut. Shape is upright in youth (often multi-trunked), with low wide-spreading branches, and rounded at maturity. Plant late-flowering cultivars to avoid severe frost damage.  Best to plant in protected location against frost and strong winds, but avoid southern exposures near structures, as buds may be encouraged to open too early.   It makes a great specimen tree, a lawn tree, patio tree, or planted in a park or recreation area. This pant has pest and disease problems.

This tree is mildly resistant to damage by deer and tolerates air pollution.
