Cornus drummondii: Roughleaf Dogwood1

Edward F. Gilman and Dennis G. Watson2

Introduction

This small, spreading, deciduous tree has 1- to 5-inch-long, olive green leaves with paler undersides. During the summer months, roughleaf dogwood produces many off-white, four-petaled, open flowers, and these are followed by many small, round fruits which ripen from August to October. Roughleaf dogwood forms a dense thicket of intertwined branches, making it ideal for use as a hedge, border, or as a cover for wildlife. At least forty species of birds are known to feast upon the fruits.
