Grown in China for twelve centuries for its medicial uses this spiny deciduous shrub may become the next health food fad but is a useful garden plant too. The outstanding feature of the plant is clusters of pale yellow to dark orange edible fruit which contains more vitamin C than oranges or lemons. The fruits ripen in the fall and persist into the winter. The inconspicuous flowers lack petals and are produced in the spring with male and female flowers on separate plants. One male plant can service several females but a male plant must be in the area for berries to be produced. The narrow leaves are gray-green on the upper side, silvery on the bottom with a rough surface. The root system is extensive making the plant valuable for soil stabilization. The roots also fix nitrogen from the air and transform insoluble chemicals in the soil into soluble forms so that they are more available to plants. Sea buckthorn tolerates salty conditions, drought, and a large variety of soil types including wet ones. It is especially useful for sea side plantings but can be used effectively in borders and the sunny locations of woodland gardens.
