Ruby Vase® Persian Ironwood is an excellent choice as a street tree or a showy specimen for small spaces. The habit is a narrow vase shape with tight upright branching. New leaves emerge in spring with an attractive red margin. The green Hamamelis-like foliage is clean and disease resistant all summer, turning lovely shades of yellow, orange and red in fall. The small reddish purple spidery flowers are borne in winter on the twigs, providing food for winter pollinators, and the bark of older plants is attractive patches of green, tan and gray.
