Centella is a low-growing creeping perennial that thrives in moist, sandy soil. Leaves are in clusters at regular intervals along strong underground stems. They are rounded, or fan-shaped, and point upward. Margins of the leaf are finely scalloped and often tinged with red. Flowers of centella are seldom seen. They are greenish-white and grow inconspicuously near the surface of the soil. If centella is allowed to grow unchecked, it can soon cover large areas of turf.
