Aggregate fruit

category of fruit

An aggregate fruit is a fruit that develops from a single flower, but the flower has more than one ovary, and the ovaries join together as the fruit grows.[1]

A raspberry fruit is an aggregate fruit. The ovaries that make up the aggregate are called drupelets
The fruit that grows from an Aquilegia flower forms from several ovaries. The fruit is an aggregate of "follicles". However, because the follicles are not connected to each other, it is not considered to be an aggregate fruit

A fruit that grows from just one flower that contains just one ovary, is not an aggregate fruit but a simple fruit.

Not all flowers with multiple ovaries grow into aggregate fruit; the ovaries of some flowers do not become tightly joined together to make a larger fruit.

Aggregate fruits may also be accessory fruits. In accessory fruits, parts of the flower that are not the ovary become juicy and form part of the fruit.

Aggregate fruits include:

  • Raspberry
  • Blackberry
  • Strawberry is an aggregate fruit and is also an accessory fruit. The small dark-coloured dots on a strawberry are the ovaries. The juicy part of the strawberry grows from the base of the flower.
