Sweet William Rockin Purple, also known as Dianthus, is an attractive addition to any garden bed, border or container planting. It produces eye catching, vibrant regal purple, ruffle edged, neatly serrated and suffused, star shaped blooms on massive 18" to 20" inch tall plants that form a mounding habit with intense tuffs of flower clusters on top. An long season bloomer, Rockin Purple will put on a color showcase from early spring all the way until first frost. This crossover ornamental also makes a fabulous cut flower with a subtle, lovely, clove-like scent. This high performance perennial will return year after in your garden. Pelleted seed. Packet: 25 seeds.
