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. |
