Forsythia viridissima koreana 'Kumson'
Common Name: Kumson Variegated Forsythia
Forsythia viridissima var. koreana ‘Kumson’ — commonly called Kumson Forsythia — is a distinctive, deciduous shrub valued as much for its variegated foliage as its spring blooms. It forms an upright, somewhat spreading plant with green leaves highlighted by bright yellow veining, creating a unique, almost netted appearance. In early spring, bright yellow flowers appear along the stems before or as the foliage emerges, followed by the striking foliage display through the growing season. Leaves may develop attractive purplish tones in fall.
