MaximumYield explains Leaf Rosette
There are some advantages to this growth habit. For example, a plant with a leaf rosette is difficult to pull from the ground, as most often they have a long taproot and brittle leaves. A leaf rosette growth habit also increases the plant's available surface area, allowing it to gather more sunlight. In the case of succulents that grow with a leaf rosette habit, the formation and growth of the leaf cluster makes it easier for the plant to gather atmospheric moisture in an arid climate.
