New for 2014, the Sundiascia series features three diascia varieties that boast a showy form. They have a unique, upright habit and tall, sturdy flower spikes. Sundiascia varieties are bred for improved heat tolerance. Three colors are currently available: Upright Blush Pink, Upright Orange and Upright Rose Pink.
These plants will reach 12 to 15 inches tall and spread 18 to 20 inches. They are suited for pots and landscapes and also work great as a thriller in combinations.
