Mulberry is a kind of multiple fruit.
'Multiple fruit's are fruits that are formed from a cluster of flowers (called an ''
inflorescence'') growing on a
catkin. Each flower on the catkin produces a fruit (drupelet), but these mature into a single mass.
[1] Examples are the
pineapple, edible
fig,
mulberry,
osage-orange, and
breadfruit.

In some plants, such as this
noni, flowers are produced regularly along the stem and it is possible to see together examples of flowering, fruit development, and fruit ripening
In the photograph on the left, stages of flowering and fruit development in the
noni or Indian mulberry (''Morinda citrifolia'') can be observed on a single branch. First an inflorescence of white flowers called a head is produced. After
fertilization, each flower develops into a drupe, and as the drupes expand, they become ''connate'' (merge) into a ''multiple fleshy fruit'' called a ''syncarpet''.
