Top facts

The dwarf raspberry has not yet been assessed by the IUCN.

The dwarf raspberry (Rubus pubescens) is a trailing plant with stolons that can reach up to 100 centimetres in length, although it only grows to heights of around 10 to 50 centimetres (2) (3). The stolons are red in colour, slightly hairy with no thorns and are around one to two centimetres thick. Roots grow from the stolon at intervals of 2 to 15 centimetres (2). White to pale pink flowers grow alone or in clusters of up to three in a group called an inflorescence (2). There are one to three fruits on a stem (2). The fruits are deep red and usually have a few loosely attached drupes (4) (5). The dwarf raspberry has compound leaves with three toothed leaflets (2) (6).

The dwarf raspberry is found throughout Canada and northern USA, from Alaska to New Foundland and south to Illinois and Colorado (4) (7).

The dwarf raspberry grows in moist woodland (5) and on steep headlands or rounded cliffs near stream banks and bogs (2) (4). It prefers shaded areas, and becomes less common following the clearing of invasive shrubs (3).

The dwarf raspberry is a perennial herb that flowers between May and June (2) (4) (6). Reproductive stems grow from the trailing stolon (2).

There are no significant threats currently facing the dwarf raspberry.

The dwarf raspberry is abundant, and is not considered to be a species of concern (4).
