Always a good choice for three-season interest are the Winter King Hawthorn (Cratagus viridis ‘Winter King’). They’re tough, easy to prune, offer a nice spring show of white flowers in May followed in the fall by the bright red fruit that persists into winter. A nice addition to any residential or commercial site.
They will grow about 25′ high with a wide spreading crown. Site them in full sun in well-drained soil. The branches of the ‘Winter King’ do develop thorns, but much fewer than the species. Very cold hardy and also heat tolerant – Zones 4-8
