Pyracantha, also known as Firethorn, is a wonderful evergreen barrier shrub excellent as a hedge or wall covering. Foliage is typically green, but variegated varieties are also available. Large sharp and shiny thorns will make sure nobody ever passes near this plant! Great when planted underneath a window or other area where you don't want visitors. Can also be espalliered. White flowers turn into bright yellow, orange and red berries to add further interest.
Pyracantha grows best in full sun and fertile, well drained soil, although they are tolerant of most sites. Pruning is not essential but can be beneficial to control size and shape.
