The Spectabilis Forsythis, Forsythia x intermedia, is a showy border Forsythia that transplants readily. It grows at a rapid rate and is long-lived. Tolerates a wide range of soil and light conditions, but prefers full sun. Allow plenty of room for plant to spread. Withstands city conditions. Profuse, yellow, spring flowers are followed by medium green summer foliage.
`Spectabilis' (Showy Border Forsythia) is the most common forsythia. The profuse, yellow flowers of forsythia are considered by many to be the first sure sign of spring. Flowers will last for two or three weeks unless killed by cold. Often used to control erosion on steep slopes because tips of branches root naturally and plants spread easily. Suggested uses for this plant include border, specimen plant, and screen. Prune in spring after flowering so that buds for the next year can develop in the fall.
