Content Detail

White-forsythia is a small shrub with a rounded to arching habit that is great for specimen planting. Its fragrant, white flowers bloom in early spring. This early bloomer is spectacular in spring, but offers very little seasonal beauty through the rest of the year. Prune it after flowering to promote new stem growth and a fuller plant.
