Weeping Forsythia, Forsythia suspensa var. sieboldii, is an early spring blooming shrub with bright yellow flowers on widely arching branches. Its yellow flowers appear before the leaves. It is an excellent plant to grow as a bank cover because of its upright, arching form. Weeping Forsythia has a clean, green summer foliage with a weeping growth habit. The best growing area is in full sun with any reasonable soil, and it tolerates city conditions. Weeping Forsythia transplants well and grows rapidly. This Forsythia is useful on banks because the branches root where they touch the ground. It is a deciduous shrub.
