Report an issue with this species
Pyracantha is a genus of large, thorny evergreen shrubs known for their abundant clusters of bright red, berry-like fruits and decorative white blooms. These shrubs are useful as dense border hedges due to their thorns and are tolerant of clay soils, drought, and salt. While evergreen in mild climates, they can be semi-deciduous in harsher winter conditions.
