The variegated redbud, a cultivar of the Eastern redbud (Cercis canadensis), offers a distinctive ornamental presence in garden settings. Its unique foliage patterns and early spring blooms make it a popular choice for gardeners seeking visual interest across multiple seasons. This tree brings a striking element to diverse landscapes, distinguishing itself from its more common counterparts.
Distinctive Appearance
The variegated redbud displays a captivating array of colors on its heart-shaped leaves. New growth in early spring often emerges with shades of maroon, red, and pink, transitioning to a striking mix of green and white as the leaves mature. This multi-colored effect creates a dynamic display throughout the growing season, particularly noticeable in varieties like ‘Carolina Sweetheart’. Some cultivars, such as ‘Whitewater’, feature white-splashed leaves that gradually become greener as summer progresses.
Before the foliage develops, the redbud adorns itself with clusters of small, pea-like flowers. These blooms appear in early spring, often in vibrant shades of pink to purplish-pink, directly on bare branches and the trunk. The 1/2-inch flowers provide a burst of color, signaling warmer weather. Growth habit varies, with some cultivars having an upright, vase-shaped form, while others may exhibit a more compact or weeping structure, such as the ‘Ruby Falls’ redbud. Mature variegated redbuds can reach heights of 15 to 25 feet with a spread of 15 to 20 feet, though dwarf varieties remain much smaller, around 7 feet tall and 3 feet wide.
Cultivation and Care
Cultivation begins with appropriate site selection; variegated redbuds generally prefer full sun to partial shade. While they tolerate full sun, afternoon shade can be beneficial in hotter climates to reduce stress and prevent powdery mildew. They thrive in well-drained soil and are adaptable to a range of soil types, including sandy or clay, as long as they are not waterlogged. They prefer a slightly acidic to neutral soil pH.
Consistent watering is important for young redbuds during establishment. For the first month after planting, water twice a week, reducing to once a week for the subsequent two months. Once established, they become relatively drought-tolerant, though deep watering once a month or during extended dry periods can be beneficial. Apply a 2-3 inch layer of organic wood mulch around the base of the tree to retain soil moisture, regulate temperature, and suppress weeds. This mulch should extend a few inches beyond the root zone, avoiding direct contact with the trunk.
Pruning is minimal for variegated redbuds, focusing on health and shape. Remove any dead, diseased, or damaged branches promptly, ideally during the dormant season in late winter or early spring before new growth begins. To shape the tree, aim for an open ‘U’ or cup shape to promote airflow; this is best done in summer after spring growth has ceased. Fertilize with a balanced slow-release fertilizer in early spring to encourage strong new growth, which often exhibits the most vibrant variegation.
Variegated redbuds can be susceptible to pests and diseases, particularly if stressed by poor site conditions. Common issues include cankers, which manifest as sunken, black areas on the bark that can girdle branches. Pruning infected branches beyond the visible canker and maintaining tree vigor through proper watering and feeding can help. Other problems include powdery mildew, especially in areas with poor air circulation or excessive shade, and foliage-feeding caterpillars, armored scales, and whiteflies. Verticillium wilt, a soil-borne fungal disease, can cause wilting and yellowing leaves. Proper site selection and care can reduce infection risk, as there is no cure.
Landscape Applications
The variegated redbud’s features make it a versatile addition to garden designs. Its moderate size, typically 15 to 25 feet tall and 15 to 20 feet wide, makes it an excellent specimen tree, drawing attention as a focal point in a lawn or garden. Its striking leaf variegation and early spring blooms ensure continuous visual interest throughout the seasons.
It also performs well as an understory tree, thriving beneath the canopy of larger trees in woodland or naturalized garden settings. Its adaptability to partial shade makes it suitable for mixed borders, where its coloration can complement surrounding plantings. For smaller gardens or limited spaces, dwarf varieties are ideal for container planting or as compact ornamental trees. The interplay of its varied leaf colors with complementary plantings, such as evergreens for contrast or spring bulbs, can enhance its ornamental impact.
