Eastern Redbud Leaf Identification and Look-Alikes

Eastern redbud leaves are heart-shaped and smooth-edged. Virginia Tech's dendrology fact sheet describes them as alternate, simple, cordate, 3 to 5 in. long and wide, with an entire margin and a petiole noticeably swollen at both ends; green above and slightly paler below. Nebraska's tree identification page gives the same size, and Wikipedia measures them at 7 to 12 cm, thin and papery, sometimes slightly hairy underneath.

Check in this order:

• Shape and edge. A broad heart with a smooth, untoothed edge.
• The stalk. Look for the swelling where the stalk meets the twig and where it meets the blade. This is the detail most look-alikes lack.
• Arrangement and twig. Alternate leaves on a slender, zigzag twig with no terminal bud (University of Nebraska-Lincoln); Virginia Tech describes the twig as nearly black with lighter lenticels.
• Color through the season. Clemson notes the leaves emerge reddish, turn dark green in summer and yellow in fall.

• Flowers. Pink to light purple, pea-like, about 1/2 in. long, in clusters along the stems before the leaves (Virginia Tech). NC State notes they appear directly on branches and even the trunk. Davey Tree gives March to April for bloom, lasting two to three weeks.
• Pods. Flat, dry brown legumes 2 to 4 in. long with flat brown seeds about 1/4 in., maturing by late summer (Virginia Tech).
• Bark. Smooth gray to brown when young; with age ridged, furrowed and scaly, dark gray with maroon patches and orange in the cracks (Virginia Tech; University of Nebraska-Lincoln).
• Form. A small tree or multi-stemmed shrub, about 25 to 30 ft, with a short, often twisted trunk and a rounded crown (Nebraska; Virginia Tech; Davey).

Several common trees have heart-shaped leaves; our trees with heart-shaped leaves page compares eight. For redbud, the quick splits are:

• Catalpa - also smooth-edged, but the leaves are much bigger, 5 to 12 in.
• Basswood (linden) - heart-shaped but serrate, 5 to 6 in.
• Katsura - small heart-shaped leaves, 2 to 3.5 in., with blunt teeth.

(Sizes as given on our heart-shaped leaves page.)

• Other redbuds - Virginia Tech lists western redbud and Chinese redbud as look-alikes, plus honeylocust for its pods. Wikipedia recognizes three subspecies of Cercis canadensis: eastern, Mexican (subsp. mexicana) and Oklahoma or Texas redbud (subsp. texensis).

A smooth edge plus the double-swollen stalk and a flat pea pod is redbud.

Redbud is a short-lived tree with a known list of problems:

• Short life. NC State says it typically lives less than 75 years; Clemson says redbuds tend to decline from disease after about 20 years.
• Canker. Clemson calls redbuds very susceptible to Botryosphaeria canker and dieback on branches; NC State also lists verticillium wilt, leaf spots and blights.
• Pests. Borers, leafhoppers, treehoppers, scale, webworms and caterpillars (NC State; Clemson). Red-humped caterpillars can strip leaves in late summer but usually do no lasting harm (Wikipedia).
• Site sensitivity. NC State lists poor tolerance of heat, drought, wet soils and root disturbance, branches that tend to break, and high sensitivity to lawn herbicides.

How many years to first bloom is not given as a fixed number in any of the extension sources we checked. What they do say is that flowers form on older wood, including the trunk (Virginia Tech; NC State), and Wikipedia gives a 10-year-old tree at about 16 ft. Ask the nursery whether a young tree has already flowered.

WoodLens can identify a redbud from a leaf, flower or pod photo.
