rosette

A rosette of leaves at the base of a dandelion Rosette growth form of the liverwort Ricciocarpos natans. In botany, a rosette or roset is a circular arrangement of leaves or of structures resembling leaves.

In flowering plants, rosettes usually sit near the soil, but they can also be at the top of an otherwise leafless branch or trunk. Their structure is an example of a modified stem in which the internode gaps between the leaves do not expand, so that all the leaves remain clustered tightly together and at a similar height. Some insects induce the development of galls that are leafy rosettes.
