Border forsythia
Forsythia x intermedia
Border forsythia (Forsythia x intermedia) is a shrub suited to the Colorado Front Range. It matures to about 6–10 ft tall and 6–10 ft wide, needs medium water, and prefers full sun. Flower buds often kill in our late spring frosts — many years it blooms only on the lower stems sheltered by snow.
