2-3' tall, despite its name.
Aromatic grey-green foliage with long arching stems topped by lavender-blue flowers provides an eye-catching show of color nearly all summer. Creates a strong dependable low-growing hedge along any garden path. Flowers attract bees, butterflies, hummingbirds and human admiration, and the occasional feline interloper. Cut back in midsummer to encourage steady blooms.
Likes hot and dry, but will grow in any well-drained soil. Plant 18–24" apart in full sun to part shade. Z3. (bare-root crowns)
