                                According to botanists, the thing in the middle of a blackberry is not actually a stem, but a fleshy part of the plant called the receptacle, or torus. Unlike its close relative the raspberry, the blackberry's receptacle remains attached to the fruit when picked, making it solid all the way through. This essential structure provides vital support for the fruit as it grows and develops.
