Aggregate fruits are clusters of small fruits developed from the merger of several ovaries that were separated in a single flower. The flower producing aggregate fruits has more than one simple pistil. The maturing pistils stick together and behave as a single fruit. The picture above is the strawberry flower that is already developing into immature strawberry fruit. The many ovaries of the strawberry flower mature into achenes , which are then embedded on the surface of the enlarged flower receptacle. Achenes are the seed you see on the surface of the fresh strawberry, which are found in the supermarket. Examples of aggregate fruits are below and you can click on them directly for information. More other aggregate fruits will be updated soonest.
