Rosette

Definition - What does Rosette mean?

In botany, rosette refers to a plant habit whereby the leaves grow in a cluster, forming a circular pattern. Unlike most leaves, rosettes tend to grow closer to the grounds. Some popular plants that display rosettes include water fern, bromeliad, dandelion and cabbage. Plants that display a rosetted stem propagate by forming new shoots in their leaf axils or at the base.

This growth habit can also be found in perennial plants. In dandelions, rosettes can also act as a protective barrier since they make it harder to pull the flower from the ground. Caulescent rosettes have also been shown to create an extremely protective layer around plants since they tend to grow in a tall cluster. In Espeletia timotensis and Espeletia schultzii, rosettes can actually help ensure the plant’s survival by protecting it from cold injury and enhancing water balance.

Additionally, a leaf rosette has been shown to help the plant soak up more sunlight by enhancing its surface area. Succulents, for example, tend to grow in arid climates and in such cases, rosettes can help the plant gather more atmospheric pressure.
