The native eastern redbud, Cercis canadensis, is one of the first trees to flower in North Carolina. Its purple flowers adorn woodland edges and disturbed roadside habitats. The foliage is heart shaped and appears soon after flowering. The redbud is an excellent small tree—it grows 20 to 30 feet tall—and performs well in full sun or light shade. Redbud will tolerate a wide range of soil types, although soils near neutral pH are preferred. It requires well-drained soils, and is drought tolerant once established. Redbud can be difficult to establish, however, particularly bare-rooted trees. Small potted plants are the easiest to establish and late fall to early spring dormant planting is best. Because redbud has a very shallow root system, planting trees at the proper depth is critical for best performance and survival.
Redbud often begins growing as a multi stemmed plant. Early removal of all but one center stem will encourage the typical tree form and will avoid the problem of narrow crotches that split from winds or ice. Other than early shaping and trimming off crossing or rubbing branches, the redbud needs little pruning.
‘Hearts of Gold’ is a new cultivar discovered by former JC Raulston Arboretum employee Jon Roethling in a North Carolina landscape. This outstanding and unique form of our eastern redbud is distinguished by its striking, intense golden-yellow spring foliage that gradually changes to chartreuses as the summer advances. The light purple flowers are plentiful in each cluster. The actively growing shoot tips take on an orange-red tone, making a distinct contrast to the older, chartreuse-colored leaves. ‘Hearts of Gold’ will express its gold color more effectively in full sun. It is a small redbud, only reaching a height of 12 to 15 feet after five years of growth. With its small stature, golden heart-shaped leaves and tidy canopy, this redbud makes a wonderful small tree for groupings near the edge of natural woodland settings or as a single specimen.
‘Oklahoma,’ another popular cultivar, is a 2008 Showstopper Plant.
