Rockin'™ Purple Dianthus

Rockin’™ Purple is the lavender-purple selection in the interspecific Sweet William series, identified by breeder code PAS1350219. The upright plant reaches about 18–24 inches tall and 10–12 inches wide, and its lacy, lightly scented flowers suit a sunny perennial border. The breeder lists a 5a–8b hardiness range and a flowering season that spans spring and summer. ## Garden Use Place this mid-height dianthus in a border or a substantial container, with about 12 inches between plants. Its purple flowers provide a clear color accent among grasses and lower-growing perennials. The [PanAmerican Seed profile](https://www.panamseed.com/Products/022508077004341/dianthus-rockin-purple/) identifies the selection, exposure, mature size, and code. ## Growing Grow in full sun or partial sun. The series is described as reliably overwintering in zone 5 and as producing full, long-lasting plants with slightly scented flowers. The listed mature dimensions are approximate; allow room for an 18–24 inch flowering display and a spread of 10–12 inches. ## Maintenance Remove spent flower heads after the main flush when a tidy border is preferred. Water during establishment and prolonged dry weather, and avoid crowding plants where airflow is limited. In colder climates, leave healthy foliage in place until spring cleanup.
