American Yellowwood


Yellowwood flowers drooping


Introduction

The yellowwood is recognized as having one of the best flowering displays of flowering trees with its white and pink drooping flowers. Although rare in the wild, the yellowwood is hardy and can easily be an urban ornamental tree as it tolerates a wide range of acidic and slightly alkaline soils.

This tree is eligible for a $100 Tree Rebate. If you’d like help with the planting, check out our RiverSmart Homes program.
