Grower Tips: 

Best blue Hypericum. Attractive blue leaves 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.

Easily grown in average, medium, well-drained soils. Prefers rich, sandy loams. Tolerant of some drought. Northern gardeners should mulch roots in the winter. Fertilize in early spring by applying a slow release fertilizer specialized for trees & shrubs. Follow the label for recommended rate of application. Prune as needed to shape after flowering.
