Hydrangea arborescens - Wild Hydrangea
This is a loosely, widely branched deciduous shrub with flattened hairy clusters of tiny white flowers that bloom in late spring through early summer with scattered continuing flowering to September. Gray-brown stems put forth sharply toothed, dark green leaves with pale green undersides, which turn yellow in the fall. They are easily grown in medium moisture and tolerates full sun if grown in consistent moisture but are intolerant of drought, with leaves declining rapidly when dry. Bloom occurs on new wood so prune close to ground in late winter to encourage stem growth.
Sun-Semi-Shade, Average Soil, Early–Late Summer, 3-5’ Tall, Zones 3-9
