Red Mammoth Raspberry
Highbush Cranberry

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.

Highbush Cranberry produces attractive white flowers in late June and bears edible fruit that matures to a bright red colour in the late summer.

This shrub, native to much of Canada, is fast growing, and its fruit can be eaten raw or cooked into a sauce.
