An award-winning, top-performing perennial that produces dense, upright spikes of deep indigo-violet flowers over aromatic, dark green foliage. Blooms heavily starting in late spring, with regular deadheading encouraging continuous reblooming through summer. Compact, sturdy, and exceptionally low maintenance, it stands up to summer heat and humidity without flopping. Perfect for sunny borders, rock gardens, cottage style plantings, and mixed perennial beds.
