'Winter King' is the great, common cultivar of the Green Hawthorn. It was introduced to the nursery trade back in 1955 by Simpson Nursery in Vincennes, Indiana, but has not become such a common ornamental tree until recently since around 2000 AD. Its fruit are about 1/2 inch in diameter, larger than the 1/3 inch of the mother species, and they persist well into winter. It blooms white very well. It has become the most commonly planted hawthorn in many areas of the Northeast, Mid-Atlantic, and Midwest because of its great ornamental traits. It does not get Cedar Rust Disease badly, if at all, though during one really wet year I saw lots of the fruit infected with orange straps of the fungus coming out. The handsome leaves turn a good orange to red in autumn. It bears very few thorns. It is planted mostly by landscape architects at estates, golf courses, parks, parking lots, shopping centers, campuses, office parks, and various public areas.
