Cultivation | Propagation | General Uses Medicinal | Edible Uses Latin Name: Mahonia aquifolium Common Name: Oregon grape Family: Berberidaceae Author: (Pursh.)Nutt. Known Hazards: None known Mature Height: 2 Mature Width: 1.5 Habitat: Mixed coniferous woods to 2000 metres. It is found in woods and hedgerows in Britain[17].
Cultivation Notes: A very easy plant to grow, thriving in any good garden soil[11, 200] and tolerating dense shade under trees[1, 28]. It grows well in heavy clay soils and also succeeds in dry soils if it is given a good mulch annually[197]. It dislikes exposure to strong winds[K].
Plants are hardy to about -20°c[184].
Very tolerant of pruning, plants can be cut back into old wood if they grow too large and straggly[238]. Spring is the best time to do this[238].
Suckers are fairly freely produced, with established plants forming dense thickets[200].
Most plants grown under this name are casual hybrids with M. repens[67]. This species is easily confused with M. pinnata[67], with which it also hybridizes[200].
The flowers are delicately scented[245]. A number of named forms have been developed for their ornamental value[182].
This species is notably resistant to honey fungus[88, 200].
This plant is the state flower of Oregon[95].
