Catmint makes soft, grey-green, rounded mounds from 10 to 24 inches high, depending on variety. Most will be wider than tall. This perennial has lavender blue flowers from late spring to early summer, though if you shear off the first flowers, it will frequently bloom again later in the summer. Different varieties have slightly different bloom times. Leaves are attractive, crinkled blue-grey and are aromatic.
Best grown in average, dry to medium moisture, well-drained soil in full sun to part shade. Thrives in dry soils in full sun, and is very drought tolerant. Shear flower spikes after initial flowering to promote continued bloom. Divide every few years if the center starts to thin. Cut back hard, a few inches above the crown, in late winter to early spring, before new growth emerges.
