Seaside daisy. 'Cape Sebastian' is a compact selection of the ever popular seaside forming a dense mound of foliage 6 to 8 inches tall. The plants in our garden have spread slowly to 3 feet wide. Lavender flowers with yellow centers cover the foliage from early spring to summer. In our opinion 'Cape Sebastian' is the most durable and long-lived selection available and we consider it one of the best North American native plants we grow for coastal gardens. It is useful in perennial borders, meadows, or as a small scale ground cover. Hardy to 15F. Common name synonym: Beach aster
