About This Plant
A vigorous perennial with aromatic foliage and tall clusters of rich violet-blue flowers. Blooming through summer, it attracts hummingbirds, bees, and butterflies while adding height and movement to perennial borders and cottage gardens. The upright habit pairs beautifully with ornamental grasses and other sun-loving plants.
Planting & Care
How to Plant
Choose a spot with 6+ hours of direct sun. Dig a hole twice as wide as the pot and plant at the same depth it was growing, gently loosening the roots. Water deeply after planting and add 2–3 in of mulch, keeping it off the stems. Hardy in USDA zones 4-9.
Watering & Feeding
Water deeply 1–2 times a week for the first season, about 1 in per week. Keep soil evenly moist, especially during heat and dry spells. Top-dress with compost in spring; most perennials don't need much fertilizer.
Pruning & Seasonal Care
Deadhead spent flowers to encourage more blooms. Cut back after a hard frost, or leave stems standing for winter interest and tidy up in spring. Divide every 3–4 years if the center thins. Mulch in late fall to protect roots through the first winter.
