Additional Information

The Flowering Crabapple is a popular small ornamental tree with an extremely showy flower display in the spring. 'Royal Ruby' is a vigorous cultivar that produces beautiful double, rose-pink flowers every year. However, it is severely susceptible to apple scab and may look quite ragged by the end of the summer. Well-drained heavy loam soils and full sun promote best growth.
