Compact, well-branched plants rarely need control pruning. Highly uniform, high yielding and very floriferous. Strong-stemmed, spreading plants produce many eye-catching flower spikes over rich gray-green foliage. Winter hardiness, cold tolerance and good resistance to foliage diseases. Plant in full sun in exceptionally well drained, gravelly soil. Drought tolerant once established. Prune to shape in spring after new leaves appear.
