Red Mammoth Raspberry
Black Raspberry

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.

The Black Raspberry is a multi-stemmed shrub that produces edible red berries that deepen to black as they mature. The berries are flavorful and are great for fresh eating and preserves. Black Raspberry shrubs bloom in late spring with white, rose-like flowers and attract many pollinators such as bees and butterflies.

Black Raspberries are floricanes primarily fruiting on second year canes. Each spring cut back all two-year old canes, leaving only the last year’s growth.
