‘Purple Fantasy’ is a perennial plant with low mounds of upright stems, creeping vigorously from stout rhizomes. Triangular leaves emerge maroon-purple in spring, turning green and developing purple markings, with leaf undersides tinged pink; these are held on short winged stalks. Tiny pink or white flowers in 1cm pompoms bloom in profusion and are borne on stem tips of slender stems to 60cm high from midsummer to autumn.
