- Description
-
The Hawthorn genus contains many different species and varieties native to North Carolina and grown from the low swamps and river bottoms in the East to the mountain ridges is the West. Crataegus collina, or Hillside Hawthorn, is a flat-topped, horizontal branching, deciduous native shrub or small tree in the rose family found in the North Carolina mountain area in open, hardwood and conifer-hardwood forests at lower elevations. Hillside Hawthorn are sometimes used as ornamentals and provide many benefits for birds, bees and mammals including food, nesting sites and cover.
This tree will grow in sun to partial shade and prefers moist well-drained soils. The flowers appear in spring and are followed by a yellow to orange pome that is edible and a favorite of bees, wasps, birds and small mammals. It does not tolerate drought well and is often leafless by mid-August during hot summers. The branches are armed with 2-inch thorns although not as many as some hawthorns.
Larvae of the Viceroy (Limenitis archippus), Red-spotted purple (Limenitis arthemis astyanax), and Gray hairstreak (Strymon melinus) caterpillars are hosted by this plant.
Insects, disease and other problems:
Quite susceptible to rust. Numerous thorns. Fruit drop could be messy.
