Sea Buckthorn (Seaberry)

Winterberry is a small shrub that produces large quantities of bright red berries that remain on the plant through the fall and into the winter. Adding this shrub to your yard will give it a unique splash of color and attract birds, especially after the leaves drop.

Note: although the foliage is attractive on its own, you need at least one male plant near your female plants or they won't produce berries.

Sea Buckthorn, aka Seaberry, is a nitrogen fixing shrub that produces attractive berries high in vitamin C.

While we can't confirm claims that the berries are effective in treating various ailments, many people believe consuming the berries helps with arthritis, infections, and asthma, among other things.

Sea Buckthorn plants have attractive pale silvery-green leaves, dense branches, and large thorns, people like to grow in ornamental hedges or as a first row in a shelterbelt.

Note: these plants typically reach maturity and make their sex easily known (females producing fruit) in their 3rd or 4th year of growth. Our seedlings are too young to identify their sex.
