Native to a small area in central Korea, this deciduous shrub is considered “critically endangered’ in the wild but is a popular garden plant in cultivation. It produces clusters of small almond scented flowers in very early spring on leafless purple black stems. The flowers have four white to pinkish petals and yellow stamens. The leaves are glossy and dark green. White forsythia is a member of the olive family and related to more familiar yellow forsythia which it resembles. Stems bearing flower buds can be forced for a winter display. A pale pink cultivar, ‘Roseum’, is available.
