Cercis canadensis (Eastern Redbud)

One of the earliest and most reliable spring bloomers in the native palette, eastern redbud pairs a spectacular bare-branch flower display with real early-season nectar value for queen bumblebees - but it's worth knowing this species is state-endangered in New Jersey before specifying it in local restoration work.

Species Overview

Commonly called eastern redbud, Cercis canadensis is a small, deciduous tree native to the eastern United States. It grows 20 to 30 feet tall and is celebrated for its stunning early spring display of pink to magenta flowers, which bloom along bare branches before the heart-shaped leaves appear. The tree thrives in well-drained soils in full sun to partial shade and is a popular ornamental choice for landscapes and gardens.

Application

• Understory and woodland-edge restoration
• Specimen and ornamental tree plantings prioritizing early spring bloom
