Description
Looking for a better blue? Here it is! The attractive blue leaves of Blues Festival hypericum contrast with the bright yellow flowers in July and August. The combination of long-blooming yellow flowers and cool blue-green foliage is very appealing. Tightly branched, compact growth makes this a good native plant for landscaping.
