DIANTHUS

Supra

F1 Dianthus interspecific

First year flowering perennial SupraTM is fast to flower and shows exceptionally good garden performance. This interspecific cross resulted in hybrid vigor for improved heat tolerance and prolific blooming with large uniquely lacy, serrated flowers of up to 4 cm (1.5 in.) across. Supra performed extremely well in trials across Europe and the USA. Testing in Florida shows this cross has excellent heat tolerance in very warm climates.

Supra purple and pink are both All America Selections winners.
