Brambles
(blackberries) |
| |
Rubus fruticosus |
| There are many known species of blackberry, and thousands of
blackberry hybrids. The study of their taxonomy is called batology.
They differ from raspberries in that the core remains part of the fruit
whilst a raspberry separates from its core once picked. |

Blackberries can be found growing in many parts of the world but mostly in
the northern hemisphere. Wild blackberries grow on thorny bushes and are
commonly found growing among hedgerows. However, there are now many thornless
varieties that are popular for commercial production.
