Firethorn

Pyracantha
A genus of 9 species of rapid growing evergreen shrubs and small trees that are part of the large Rose family. They are very useful as free standing shrubs as well as for espaliers and hedging.
Most have toothed, deep green evergreen leaves and spiny stems. The flowers on all are white and are followed by persistant yellow to orange or red berries.
Honey Bees love the flowers and birds ( especially Cedar Waxwings love the berries )
Most prefer cool moist climates and full sun on fertile, well drained soil. They are best installed from containerized nursery stock and do not like to be moved once established.
Pruning is not required but hedges may be pruned in early or mid summer to control size.
Propagation is from seed ( sown in cold frame during mid-autumn ) or 4 inch cuttings of fresh growth taken during summer for the cultivars. Pyracantha roots easily from softwood, semi-hardwood or hardwood cuttings under mist, 1000 to 5000 ppm IBA solution in 4 to 6 weeks. The seed should be soaked in water for 24 hours then cold stratified for 3 months unless immediately sown outdoors. The seeds should be planted at 0.1 inches deep. Some species may be prone to scab, fireblight and wilt fungus.
