Frosted Hawthorn - Crataegus pruinosa



Description of Plant

Leaf: 2-2.5 cm wide, elliptical or ovate, short pointed at tip, blunt at the base, irregularly saw-toothed with 6-8 shallow lobes. Turns orange-red in the autumn.

Flower: 2.5 cm wide with 5 white petals and 20 rose-red or pink stamens. There are few flowers on long stalks in hairless clusters in the late spring.

Fruit: 10-15 mm in diameter, often slightly angled with a whitish bloom turning a dark purple-red with many small dots and a thick sweet edible pulp. The pulp contains 5 nutlets and matures in late autumn.

Twig: Hairless and with many straight spines.

Bark: The bark is gray, scaly and thin. As the tree ages the bark becomes rough and slightly furrowed.

Form: A much branched shrub or small tree with broad, rounded, dense crown of spreading branches, large white flowers and a dark purplish-red fruit.

Discussion of the Plant

The fruits of the Frosted Hawthorn are eaten by several species of birds. The dense branching of this tree provides shelter and a nesting habitat for the birds that live in the area.
