Dewberry (Dwarf Raspberry)

Killarney Raspberry is extremely robust, with some of the best cold and disease resistance available. This could be due, in part, to it being bred in Manitoba.

It is also known for its good flavor and for being firmer than other varieties, which lends to its use in processing like pies, jams, and jellies or for U-Picks.

Killarney Raspberry is a floricane-fruiting variety, meaning it primarily produces fruit on second-year canes (previous season’s new growth). They are also referred to as summer-bearing. In late winter or early spring, cut back all spent floricanes, leaving only last season's canes.

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

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.
