Dwarf and weeping ornamental trees are hot. With yard sizes of new homes getting smaller, homeowners are looking for attractive trees that will fit in small spaces. Breeders have responded by creating many dwarf and weeping versions of popular flowering trees.
Redbuds (Cercis) are the latest trees to undergo this attention. The 'Covey' redbud (Cercis canadensis 'Covey') produces bright purplish pink flowers in early spring. The tree has an umbrella form so when in bloom it looks like a cascade of color. It's hardy in USDA zones 5 to 9.
Another small redbud is the 'Ace of Hearts' (Cercis canadensis 'Ace of Hearts'). Featuring the same purplish pink flowers, this variety has small, heart-shaped leaves that are spaced close together, giving the tree a bushy appearance. It's hardy in USDA zones 4 to 9.
Both redbuds grow less than 10 feet tall and wide at maturity, can be grown in full sun or part shade, and have yellow fall foliage color.
