20 Seeds Oregon Holly Grape
Foliage: Emerging reddish, changing to light bronzed-green, turning lustrous dark green, then finally becoming a deep burgundy in Winter. Often subject to "burning" in winter, resulting in a bleached appearance of the foliage. Evergreen, alternate, odd-pinnately compound, with 5 to 9 leaflets that are individually elliptical to ovate, very spiny-dentate on the margins and glossy.
Flowers: Monoecious. Bright yellow, flowering in April, with a dense cluster of many small flowers in a large terminal and smaller lateral inflorescences, attracting many bees and mildly fragrant. The inflorescences are an attractive contrast against the previous year's burgundy foliage and the newly emerging red foliage
Fruits: Clusters of ellipsoid green berries (to .5 inch) mature to a blue-black color with a white cast (a "bloom" on the cuticle, as in Blueberries or Grapes) in August and September, and may persist into December. Berries are edible and are eaten by birds and a variety of wildlife.
Twig: Main stems are largely unbranched, with compound leaves arising directly from main stems; green when young, turning gray-brown with age. The stems and twigs have a thickened, corky appearance.
Bark: Gray-brown and smooth or slightly rough, sometimes appears striped as the bark matures.
Form: A tall, erect, evergreen shrub reaching 3 to 10 feet fall. Most commonly grow in clusters with numerous, erect, unbranched stems.
