Firethorn is a large, evergreen shrub that is cherished for its spectacular fall and winter display of scarlet fruits and ability to withstand dry and drought conditions. Shooting long lanky stems in all directions, firethorn typically grows into a tangled mound up to 10 ft in height and 12 ft wide. It is armed with sharp thorns that hide among the dark, glossy green leaves. Clusters of small white flowers appear in spring. These are up to 2 in across and are close together creating the appearance of nearly solid surface of flowers. In fall the 1/4 in berries begin to ripen and persist through winter and into early spring depending on climate and appetite of the local bird population. Under bright sunny conditions the berries are plentiful but expect smaller crops in shadier situations. Firethorn is very fast growing and cultivars and hybrids are available that may be considerably more compact or otherwise differ in form from than the species. These also vary by form, fruit color and hardiness.
