Red Mammoth Raspberry
Jewel 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 Jewel Raspberry is one of the most popular black raspberry varieties, as it is consistently high-yielding and produces large, firm, and sweet berries. This cultivar is among one of the first raspberries to ripen each year, with berries ready for harvest in early to mid summer and is a vigorous grower.

The Jewel Raspberry is self-pollinating, and is a primocane variety meaning that it produces fruit on first years' growth. Prune stalks down each winter or early spring to get higher fruit yields and easier harvesting.
