Abstract
Abstract ‘Prairifire’ is an attractive new ornamental crab apple with bright red-purple flowers, blooming 5–7 days later than other cultivars with that color, and immune or highly resistant to several destructive diseases of Malus.. Flower production is heavy and annual on both spurs and axillary buds on 1 year shoots. The flower color does not fade seriously nor develop an unattractive “muddy” appearance. Since axillary flowers develop somewhat later than do those on spurs, the flowering period is extended up to a week longer than if spurs were the only flowering sites. The small, dark-red fruits either dry on the tree or are eaten by birds, thus eliminating any clean-up problems from dropped fruits.
