Mahonia aquifoliumAlso known as:
holly-leaf Oregon grape,
Berberis aquifolium, Berberis piperiana, Odostemon aquifolium
Mahonia aquifolium is an ornamental broad-leaf evergreen with year round visual interest. The leaves are large, deep-green, glossy and holly-like. They provide a perfect background for the large terminal clusters of small bright yellow flowers that emerge in spring. These are followed by equally showy clusters of purple grape-like fruit, hence the common name "Oregon grape" (it is also the state flower of Oregon).
Mahonia aquifolium is very easy to grow and low maintenance. It is tolerant of a variety of soils, including poor ones, and is also drought resistant within its natural range. It is perfectly adapted to shaded conditions and can be exposed to more sun in cooler areas. It can be used as a foundation plant for northern exposures, and will provide a perfect backdrop for spring bulbs. Does not produce a lot of leaf litter. A springtime bloomer, March to May, with fruit ripening in summer. Zones: 3-9
Propagate from freshly collected seeds that have been stripped of any fruit pulp. Germination rates are low. Can also be propagated from stem cuttings and root cuttings. Off-shoots from mature plants can be safely dug out and transplanted.
Although very tart, the berries are edible raw, preferably mixed with other fruit that will act as sweeteners. They can also be made into jellies or preserves, and fermented into wine. The roots have been used to produce a yellow dye, and also used medicinally as a panacea. Due to its high level of adaptability, Mahonia aquifolium can become invasive outside of its natural range, displace other native species, and is considered a weed in some areas.
