Red Mammoth Raspberry
Double Delight 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.

Double Delight Raspberry is known for its medium-large berries that have a sweet-tangy taste. They ripen from late summer to early fall, extending the raspberry season. Known for having larger yields, it is suitable for both home gardens and larger commercial projects. The berries are well suited to fresh eating, freezing, baking, and preserves.

Double Delight Raspberry is a primocane-fruiting variety, meaning it produces fruit on first-year canes (the current season’s growth). They are also referred to as ever-bearing or fall-bearing. Cut stalks down each winter or early spring to get higher fruit yields.

Raspberries are self-fertile, meaning they do not require cross-pollination from another variety to produce fruit
