We have two native species of Oregon Grape growing on the property, this one, Mahonia aquifolium and the Dull Oregon Grape (M. nervosa). We grow a third species in the garden. Tall Oregon Grape has shiny leaves that look as if they are wet- hence the latin name, with smaller numbers of leaflets on each leaf. The leaves vary quite a bit from plant to plant in leaflet shape and in winter colour. Some plants have leaves that turn a nice burnished burgandy colour, while most stay green. Yellow flowers in early spring and blue berries in late summer make this a particularly attractive species. This is one of our natives that is used extensively in horticulture. I remember seeing large boulevard plantings of this when we visited Holland a few years ago.
Two biologists on a beautiful property armed with cameras, smart phones and a marginal knowledge of websites took up the challenge of documenting one species a day on that property. Join along! Posts and photographs by Leah Ramsay and David Fraser (unless otherwise stated; started January 1, 2014.
