'Purple Pinwheel' is a very old daylily in my garden. It's one of the first I planted years ago. It blooms every summer, mid summer in my Vermont garden. Bloom size about 4 1/2 ", and its a diploid, bitone. In my garden the bloom is purple, not a black purple, with a slightly darker eye, and chartreuse throat. The white midrib markings on the petals distinguishes the bloom and creates that pinwheel effect.
