Pyracantha is a small genus of spiny evergreen shrubs in the rose family. White flowers are followed by a showy display of bright red, orange or yellow fruit which persist into fall and winter. Aside from their ornamental interest, the dense thorny growth habit provides a natural barrier and cover for wildlife. Like other members of the rose family, Pyracantha is susceptible to several fungal diseases, including scab and fire blight. There are resistant cultivars and hybrids available.
