F1 Dianthus interspecific

Dianthus Supra is a completely new interspecific hybrid with a compact and strong branching plant habit. It is an interspecific cross that imparts hardiness to this series.

Supra is fast to flower and shows an exceptionally good garden performance. This new interspecific cross has 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 that this cross has improved heat tolerance in very warm climates.

Supra Purple is an All American Selections winner and received the Fleuroselect Quality award. 

Supra Pink also received the 2017 All America Selections Award.
