14. The fruit of the mulberry, similar
to the blackberry, is an
aggregate fruit that is composed
of many smaller fruits called
drupes. Therefore, botanically it
is not a true berry. The skin is
smooth and fragile, and the color
changes from green to red to
dark purple as it matures. There
are also white mulberry varieties
that exist. Mulberries have a
stem that persists on the fruit
when it is picked from the tree,
distinguishing it from
blackberries and raspberries.
