Downy Hawthorn
Encyclopedia
Crataegus mollis, known as Downy Hawthorn or Red Hawthorn, occurs in eastern North America
from southeastern North Dakota
east to Nova Scotia
and southwest to eastern Texas
. This tree inhabits wooded bottomlands, the prairie border, and the midwest savanna
understorey.
This tree grows to 10–13 m high with a dense crown of thorny branches and an ash-grey trunk. The leaves
are 5–10 cm in length and often drop in late summer due to defoliation by leaf diseases. The tree seems to suffer little from the early loss of its leaves. Among the earliest in the genus to bloom, Downy Hawthorn also has earliest ripening fruit, which decorate the defoliated tree in late summer and early fall. It is closely related to Crataegus submollis
, but the two species have separate native ranges. Amongst other differences between these two species, C. submollis has approximately 10 stamens, whereas C. mollis has approximately 20 stamens per flower.
The white flower
s are borne in clusters at the end of the branches in spring. The bright red edible fruit ripens in late summer and early fall and falls soon after.
This species is a target of Gypsy moth
s. Leaf rusts and fireblight
are among the many foliage diseases to affect this species. The sharp thorns are a hazard.
This species is uncommon in cultivation.
