Description

Dwarf Hawthorn is a native deciduous shrub or small tree in the rose family. It is found naturally in forests, roadsides, rock outcrops, and other disturbed lands with xeric to sub-xeric conditions in all areas of NC. It grows as a  spreading shrub or small tree with a rounded crown and crooked thorny branches. It is heat tolerant with good fall color. Solitary flowers appear in spring and are followed by fall fruits.

This shrub prefers well-drained soils on the drier side in sun to partial shade. It could be used as a barrier, hedge or as a wildlife plant in naturalized areas. It is beneficial to birds, small mammals and pollinators. It may be difficult to find for sale.

Quick I.D. Hints:

  1. One flower with white to cream colored anthers
  2. Leaves small and unlobed
  3. Straight fine thorns
