Abeliophyllum–commonly called white forsythia– is a small deciduous shrub grown for its fragrant early-spring flowers. Abeliophyllum is not a true forsythia, but it blooms at the same time as forsythia in very early spring. Flower buds are less likely to be killed by late frosts than those of true forsythia.
Abeliophyllum is an open, spreading shrub. It grows to about 5 feet (1.5m) tall and wide. Flowers appear ahead of leaves. Abeliophyllum bears masses of small (1/2 inch) slightly fragrant flowers densely packed on arching branches. Oval, blue-green leaves appear by summer.
Grow Abeliophyllum in a sunny border or plant it near a warm wall. Abeliophyllum can also be planted in mass.
Abeliophyllum is a genus of one species native to the hills of Korea.
