Dewberry (Dwarf Raspberry)
Red Mammoth Raspberry

Dewberry (Rubus pubescens) is a native, low-growing perennial that spreads by creeping stems to form a natural groundcover. In spring, it bears small white flowers that attract pollinators, followed by bright red edible berries resembling tiny raspberries. They are an important food source for birds and mammals.

Widespread across Canada, Dewberry serves as a larval host plant for butterflies such as the Spring Azure (Celastrina ladon), adding to its ecological value. It is a suitable choice for naturalization, pollinator gardens, habitat plantings, and ecological restoration projects.

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.
