Eastern redbud, Cercis canadensis
 
Eastern redbud is a stunning small tree that bursts into clusters of rose-pink to light purple flowers in early spring before the leaves emerge. It grows 6-9 m tall and wide. The distinctive heart-shaped leaves appear after flowering, followed by flat seed pods that persist through winter. The leaves turn a golden colour in the fall.
 
Ecology:
Redbud is highly valued as a critical early-season nectar source for pollinators emerging from winter hibernation. Its flowers attract bumble bees, mason bees, mining bees, sweat bees, long-tongued bees and hummingbirds. It supports the pollen-specialized bee Habropoda laboriosa. Its beautiful heart-shaped leaves have the right chemical properties to provide antimicrobial nesting material for leafcutter bees. The leaves also serve as a larval food for Lepidoptera, including Henry's Elfin butterfly and many moths. Cardinals, grosbeaks, finches, chickadees and other songbirds eat the seeds. 
 
Growing conditions:
Eastern redbud prefers full sun but still blooms in partial shade. It grows quickly in moist, rich, well-drained soil and is highly adaptable to various soil types, including clay, loam, and sandy soils. It is drought-tolerant once established. Avoid poorly drained or flooded sites as the tree does not tolerate wet feet. Native to open woodlands, woodland edges, streamsides, and savannahs. All trees are best planted in spring or fall. Deer resistant. It is a relatively short-lived tree with a lifespan of approximately 20 years.
