Ruby Falls is a compact weeping cultivar of Cercis canadensis that combines a cascading branch structure with dark burgundy heart-shaped leaves and rose-pink flowers. It matures at 6–8 ft tall and wide, making it a practical specimen for small gardens, patios, and tight spaces. Flowers emerge directly from bare branches and trunk in early spring before leaves unfurl, a botanical trait called cauliflory that gives the tree an unusually dense floral display.
At least half a day of direct sun is needed to hold burgundy leaf color; too much shade shifts foliage toward green. Ruby Falls tolerates a range of soils but requires good drainage — standing water promotes canker and root rot. Keep a 2–3 in mulch ring clear of the trunk to conserve moisture without trapping pathogens. This cultivar is grafted, so any upright, green-leaved growth emerging from below the graft union is rootstock and must be removed at the base promptly or it will overtake the weeping form.
The flowers of Cercis canadensis are edible and have been used raw in salads and as a pickle. Cherokee peoples used bark preparations as an astringent for dysentery.
Redbud Canker
Sunken, discolored lesions on stems or trunk with cracked or peeling bark at the margins. Branches beyond the canker wilt and die back from the tip inward. Affected bark may reveal dark staining in the wood beneath.
Prune affected branches 6–8 inches below the visible canker margin using sterilized tools. Dispose of removed wood away from the site. Maintain tree vigor with consistent moisture and mulching. No effective fungicide treatment once canker is established; prevention relies on avoiding mechanical injury to bark and minimizing drought stress.
Botryosphaeria Canker
Dark, sunken cankers on stems and major branches, most often occurring after drought stress or mechanical wounding. Bark peeled back from affected areas reveals brown, discolored wood beneath. Branch tips wilt and die back progressively inward.
Prune infected branches at least 6 inches below the visible canker margin using sterilized tools, and dispose of all cuttings away from the garden. Reduce plant stress by maintaining consistent irrigation during dry periods and avoiding bark wounds during maintenance. No curative fungicide is available; keeping plants vigorous is the primary preventive strategy.
Verticillium Wilt
Lower leaves yellow and wilt, often on one side of the plant, with brown streaking in the stem and crown tissue when cut open. Plants are stunted and decline over the season.
Remove and destroy affected plants. Avoid planting in soil that has grown infected tomatoes, peppers, or other susceptible crops. Rotate beds and improve drainage; there is no cure once a plant is infected.
Fungal leaf spot
Brown or purplish spots on the leaves, often ringed with a yellow halo, that spread and merge in warm, humid, or wet weather; heavily spotted leaves yellow and drop early.
Pick off spotted leaves and clear fallen debris to remove overwintering spores. Improve air circulation by thinning, and water at the base so foliage dries quickly. If it persists, apply a copper- or sulfur-based fungicide at the first sign.
