Description

The Purple-leaved eastern redbud is one of the most popular foliage accent trees in commercial landscapes and residential gardens throughout the Inland Empire. It is a small to medium size deciduous tree growing with a low branching habit, that can eventually reach 25-35 ft. tall and as wide. Bright purple-red new foliage emerges in spring and then turn pale green by the end of summer. These leaves are heart-shaped with a long pointed tip, and grow 3-6 in. across. Clusters of showy magenta flowers occur in early spring and are followed by small bean-type pods. Foliage turns bright yellow-gold in fall.

Purple-leaved eastern redbud is naturally adapted to areas with cool and moist winters and regular summer for best flowering and foliage performance. In hot Inland Empire locations, it is best to select locations that are protected from hot afternoon sun during the summer months. It is an excellent shade tree for gardens, patios and front yards where it provides year around interest.

Water Needs

The Purple-leaved eastern redbud grows best without moisture stress and regular irrigation is recommended throughout the year. The chart shown below provides a baseline guide to the monthly irrigation schedule and volume of supplemental water needed to maintain healthy growth throughout the average year. The high and low range of moisture indicates it can grow with varying amounts of water; higher amounts of water will result in stronger springtime flowering performance and better summer foliage character.

Maintenance

Prune when young as necessary to establish good long-term from. Best grown as a multi-trunk large shrub / small tree if there is room, but can also be grown as a single trunk tree. Organic mulch of 3-4 inch depth under the canopy, but held away from the trunk and root crown is ideal. Ideally plant in winter, when dormant, but fall is acceptable as well. Prune late fall or winter (D,S).
