A great woodland edging plant with attractive, clean leaves and fresh pink blooms. It can easily spread where conditions are ideal, but is easily pulled back by hand.

Description and Growing Information
Flowering Period
General Description
The flowering raspberry is a beautiful shrub that has very large palmate leaves and a pretty purple flower with a yellow center that is hard to miss. For these reasons, the plant can be often spotted in residential gardens. It can also be cultivated for its fruit which are usually turned into jams or other preservatives. This plant also attracts all sorts of wildlife, including species like the bumble bee, honey bee and native bee. Many birds will also make their nests in the plants as they find it so dense that it provides a safe and suitable home.
Since the flowering raspberry is an attractive looking bush that produces an edible fruit, it is not uncommon to find it in residential gardens. Raspberry plants are fairly aggressive in terms of growth; they grow rapidly and spread quickly due to their tenacious root systems. The flowering raspberry, however, is slightly less aggressive than other Rubus species. It can grow very large (up to 3 m) and has attractive, wide palmate, simple leaves, therefore it can be used as a decorative plant or for its fruit.
Plant in partial shade with a soil pH that is 6.8 or below. Granular and/or sandy or deep forest loam are ideal.
Dense and upright and when mature forms thickets.
ID Characteristic

Rubus odoratus is fairly immune to pests and diseases. Although there is one fungus that is of concern: the honey fungus. The flowering raspberry will attract all kinds of insects pollinators but most common will be the bee.
