Indiglo Girl has rich indigo-blue flowers in dark calyxes that seem to glow against the foliage. It combines the large, bright flowers of meadow sage with the full, bushy leaf cover of the classic garden salvias.
It blooms from late spring into early summer and will flower again later if you cut off the spent spikes. Plant it in sunny borders or mass plantings; pollinators love it and deer and rabbits leave it alone.
What it looks like
Upright flower spikes 6 to 8 inches long lined with fairly large two-lipped florets in rich indigo-blue, held in dark purple calyxes. Spikes are numerous and rise over a full mound of leaves. Leaves are lance-shaped to oval, 2 to 4 inches long, green, aromatic and crinkled. The plant forms a vigorous, bushy, upright clump 20 to 22 inches tall and 20 to 28 inches wide. At peak it is a dense mound of glowing deep blue spires.
Growing it with lavender
Salvia wants the same full sun and lean, well-drained soil as lavender, and its upright spikes echo lavender's form while filling the gap before and after the main lavender bloom.
Care
Plant in full sun in average, well-drained soil; it is drought tolerant once established. Hardy in zones 3-8; shear the plant back by about a third after the first flush fades to encourage fresh growth and another round of flowers.
