Sea Buckthorn (Seaberry)

Developed by the University of Saskatchewan Fruit Program, SK. Red Mammoth was a high yielding and firm variety released in 1999. It produces distinctively large bright red berries about 1 inch wide. It is also more cold hardy than older raspberry cultivars. Red Mammoth is firm which makes it suitable for commercial production and sweeter than Boyne. Floricane.

Needs to be trellised as canes are not as sturdy as other varieties.

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: Sea Buckthorn is dioecious, meaning male and female flowers grow on separate plants. Both are required for fruit production, though only female plants bear fruit. A plant’s sex typically cannot be identified until its third or fourth year. Our seedlings are too young to determine their sex.
