Oregon Grapeholly (Mahonia aquifolium-syn.Berberis aquifolium) Shrub - Flowering Shrubs. The Oregon Grapeholly botanically belongs to the Berberidaceae family. It is native to various regions of southwestern Canada to northern California. It is a medium-sized shrub, perennial and evergreen, growing up to 3 m tall. It has a medium growth rate, upright habit and oval shape. Its spiny leaves are alternate arranged, dark green, odd pinnately compound, ovate in shape, having a leathery texture, with dentate-undulated margins. The plant flowers from mid to late spring. Its monoecious, fragrant flowers, borne on raceme inflorescences, are yellow in colour and stellate in shape. Ornamental fruits (violet berries) follow. The Oregon Grapeholly is quite easy to grow, as long as it is not exposed directly to the sun. Its growth is favoured when placed in semi-shaded areas, and fertile, organic-rich soils with excellent drainage. It can be used both in gardening and in landscape architecture, planted as specimen, in groups and also in compositions with other plants.
► It is offered at a price determined by the particular characteristics of the plant, such as the size of the pot, its height, age and shape. Large plants are also available for sale (and planting) upon prior arrangement. In any case, the price or prices listed are indicative.
