'Winter King' Green Hawthorn has white flowers in late spring, brilliant red fruit well into the winter, and silver bark. Fruit are larger than the straight species and eaten by many birds including cedar waxwings. Crataegus viridis 'Winter King' has a lovely rounded habit, is more disease resistant and is largely spinless (with only occasional small thorns to 1.5" long). One of our favorite multi-season small trees. Introduced by Simpson Nursery, Vincennes, IN in 1955.
