Red Mammoth Raspberry
Indigo Treat Haskap (Honeyberry)

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.

Indigo Treat has fruit similar in size and firmness to their Tundra variety, making it suitable for commercial production or your home garden.

Indigo Treat, like the Borealis Haskap, does not self-pollinate well. We recommend another variety, such as Honeybee or Berry Blue Honeyberry, be planted at a minimum 1:8 ratio with it to boost fruit production. Many experts suggest the highest Haskap yield comes from fields planted with the most varieties.

Due to stronger interest in newer cultivars, 2015 will be our last year selling Indigo Treat.
