The Double Flowering Plum (Prunus × blireiana ‘Plena’) is a small ornamental deciduous tree prized for its abundant, showy, double pink blossoms that appear in early to mid-spring before the leaves emerge. The tree has a rounded to slightly spreading canopy with smooth, dark reddish-brown bark. Its glossy, deep green leaves turn a subtle bronze to red in fall, adding seasonal interest. This tree is primarily grown for its stunning spring flowers rather than fruit and serves beautifully as a specimen or accent tree in a garden.
