I originally ordered and received packet of 15 seeds from Park Seed Co. for these Creme de Cassis. They are a very pretty, mostly double, and long blooming. They are noted by Park to be perennial, and they did bloom the first year of planting. They continued flowering prolifically through the first light frosts. No problems looking ragged or with any kind of pest or mildew. They were difficult to keep upright however, because of their height (over 6 feet) and top-heaviness. Still, definitely worth it! Will try keeping these around for sure.
