Blackberry - Fruit


The blackberry is an aggregate fruit that is composed of many smaller fruits called drupes. 

The fruit is very dark purple with smooth, fragile skin. In the middle of the cluster is a greenish-white core that extends to almost the bottom of the berry. Blackberries can be easily confused with raspberries, but raspberries (including black raspberries) have a hollow center.

Blackberries are red and hard when they are immature and turn black and shiny when they ripen.
