Corneliancherry dogwood (Cornus mas, Cornaceae) is a slow-growing deciduous shrub or small tree from central and southern Europe and western Asia, reaching 20 to 25 feet tall. It is among the earliest trees to bloom, producing small yellow flowers in short-stalked umbels on bare branches in March, well before leaves emerge. Oblong red drupes (1.6 centimeters) ripen in mid-summer and are edible.
Corneliancherry dogwood grows in sun to part shade on adaptable soils (pH 5.0 to 7.5) with moderate water needs and low drought tolerance, hardy in Zones 4a to 8b. It has resprout ability and reaches about 25 feet at 20 years. It is deer-resistant and tolerates clay soil. Maintenance is low. Disease and pest associations mirror those of the Cornus genus broadly. The fruit is used in preserves and beverages in parts of Europe. No cultivars are documented in the profile.
