Forsythia is a fast growing, deciduous shrub with upright-arching, square-stemmed branches covered with oval to elongated oval, medium to dark green leaves (3-5” long and 1” wide) which have toothed margins in the upper half of the leaf. Most varieties mature 6-10ft tall and spreading to as wide as 12ft, but some compact varieties rise to only 30inches tall. Shrubs are grown for their vivid, 4-lobed, abundant lemony colored flowers (each 1.5in long) which bloom in clusters of 2-6 flowers along the branches in late winter to early spring. Flowers usually bloom before the leaves emerge but there have been some cases where they bloom at the same time. Fall foliage is the ordinary yellowish green but if you live in a colder region, they can occasionally turn purplish.
