A great little blue from Dr. Benedict that is the 6th or 7th generation hybrid of H. 'Dorset Blue'. Thick wedge-shaped leaves form a nice small clump of blue leaves that have good substance and are topped with pale lavender flowers in summer.
H. 'Blue Sliver' makes a small clump of narrow wedge-shaped, powder blue leaves. The 15" wide clumps are topped in late spring with 1' tall spikes of lavender flowers.
