Aesculus pavia #3 (Red Buckeye)

Red Buckeye is a small tree or clump-forming shrub native to the Southeastern US. It has an irregular, dense, rounded shape at maturity that can be pruned and shaped to achieve either form. It is early to leaf out in spring, with lustrous dark green, palmately compound leaves. Flowering occurs in late April to early May and lasts 2-3 weeks. Brilliant red panicles attract Ruby-Throated Hummingbirds and long-tongued bees, who receive an early source of nectar and cross-pollinate the flowers in exchange.

Red Buckeyes are at their best in partial sun with moist, well-draining soil. They are able to flower well in the shade and hold their leaves longer into the summer and fall. They are slow to mature at 6-8″ of growth per year, but they are well worth the patience! Fall brings no significant change to the foliage color, and leaf drop occurs earlier than most other tree species. Insect pests and diseases rarely bother this species.
