Walker's Low catmint makes a relaxed, aromatic mound of gray-green foliage about two feet tall, covered in lavender-blue flower spikes from early summer into fall. It has the soft, billowing look of lavender but with far more tolerance for our humidity, and pollinators work it constantly.

Give it full sun and well-drained soil and then neglect it; drought, deer, rabbits, and rocky ground all fail to bother it. Shear it back by half after the first big flush and it regrows fresh and blooms again. Fine draped over a wall or edging a walk.
