Sea berry is a little known European Berry. It is very hardy and grows on almost any soil type. It is drought-tolerant once it is established, seedlings however require consistent moisture. Seaberries are hardy in zones 3 - 7, they resemble citrus in taste and composition and are a tad tart. The berries are the size of a large blueberry and have a citrusy flavor, in fact Europeans use sea berry juice as a substitute for Orange Juice.
They are somewhat compact, attaining 6 to 12 feet at maximum maturity and are relatively easy to grow. Two plants are needed to produce fruit a male and female as they grow on different plants. They are wind pollinated and should be appropriately spaced, 6 to 8 feet is ideal. The berries ripen in late summer and Autumn and will remain on the bush, unfazed through hard frosts, they do not over winter. The male shrub remains covered in burnt orange flower buds in winter and spring, they produce larger flower buds than the female.
Seaberries should be planted in the spring. Full sun and most soil, sandy soil or even gravel is acceptable as they are very hardy and tolerant of adverse conditions.
