Forsythia

Forsythia is a deciduous shrub genus valued for clusters of bright yellow flowers that open on bare stems in early spring. Species and garden hybrids vary in size, hardiness, and branch form, so choose a named cultivar when you need a specific mature footprint or cold tolerance. ## Habit and seasonal interest Depending on the species, plants range from compact shrubs to large, vigorous forms with upright or arching branches. The genus reference from [NC State Extension](https://plants.ces.ncsu.edu/plants/forsythia/) gives a height range of about 3–10 feet and a width range of 4–7 feet. Flowers appear before the leaves, and bare branches can also be cut for indoor display. [Wisconsin Horticulture](https://hort.extension.wisc.edu/articles/forsythia-forsythia-spp/) notes that size and hardiness differ among species and hybrids. ## Siting and care Plant in full sun for the heaviest bloom; part shade is tolerated, though flowering may be lighter. Forsythia grows in loose, medium-moisture, well-drained soil and tolerates average garden conditions. Allow room for the mature plant in a mixed border or hedge rather than relying on frequent hard pruning to contain it. ## Maintenance Flowers form on old wood. Prune immediately after spring flowering, removing selected older stems at ground level to refresh an established shrub while preserving the following year’s buds.
