Culture

Easily grown in average, dry to medium, well-drained soil in full sun. Drought tolerant. Moist, rich fertile soils may encourage unwanted succulent growth. Tolerant of urban pollution.

Noteworthy Characteristics

This cultivar is one of the best hawthorns for landscape purposes. A small deciduous tree with a rounded, vase-shaped habit which typically grows 25-35' tall. Features profuse white flowers which appear in May in 2" diameter clusters and toothed, elliptic, glossy green leaves (to 3.5" long) which turn red to purplish red in fall. Small, crabapple-like fruits (1/3" diameter) mature in fall to a bright red and persist throughout the winter. Fruits are technically edible, but are best left for the birds. Stems are an attractive silver-gray. The bark of older trunks often exfoliates to expose an orangish-brown inner bark. Unlike most hawthorns, this cultivar (as well as the species) is largely spineless, with only occasional small thorns (to 1.5" long).

Problems

One of the most disease-free hawthorns. As with most hawthorns, there is some susceptibility to rust (rust stage of cedar hawthorn rust where eastern red cedars are present in the area) and fireblight, but this cultivar is noted for its good resistance to both diseases. Scale and aphids are occasional insect pests.

Garden Uses

Excellent spring flowering tree for lawns and streets. Good fall color and persistent fruit help provide year round interest. Pollution tolerance makes it a good candidate for urban plantings.
