The sea-buckthorns are deciduous shrubs in the genus Hippophae, family Elaeagnaceae. They are tolerant of salt in the air and soil, but demand full sunlight for good growth and do not tolerate shady conditions near larger trees. They typically occur in dry, sandy areas. Common sea-buckthorn has branches that are dense and stiff, and very thorny. The leaves are a distinct pale silvery-green, lanceolate, 3�8 cm long and less than 7 mm broad. It is dioecious, with separate male and female plants. The male produces brownish flowers which produce wind-distributed pollen. The female plants produce orange berry-like fruit 6�9 mm in diameter, soft, juicy and rich in oils. Sea-buckthorn berries are edible and nutritious, though very acidic (astringent) and oily, unpleasant to eat raw, unless 'bletted' (frosted to reduce the astringency) and/or mixed as a juice with sweeter substances such as apple or grape juice. Here the remaining berries are dying off. Picture taken at Wells-next-to-the-Sea, Norfolk, 10th February 2011.
