Tall Tails is a large catmint that brings height and structure to a sunny planting, reaching 28 to 32 inches tall and about 3 feet wide. Its upright framework is noticeably stiffer than older tall catmints, so it holds its shape better.
Soft lilac-blue flowers open early in the season and continue for a long stretch, giving pollinators an early source of nectar. It is drought tolerant, easy to grow and deer and rabbit resistant, and it works well filling the middle of a border or anchoring a mass planting.
What it looks like
Long, upright spikes of small, tubular, two-lipped flowers in soft lilac-blue rise from sturdy, branching stems, held in dusky purple calyxes. The leaves are small, oval to heart-shaped, gray-green and scalloped. The plant forms a large, upright-rounded clump about 28 to 32 inches tall and 36 to 40 inches wide with stems that stay fairly rigid. At peak bloom the tall spikes create a broad, soft blue-violet cloud.
Growing it with lavender
Catmint is one of lavender's best partners: it wants the same full sun and lean, well-drained soil, and its soft blue-violet haze blooms alongside lavender and keeps going after the lavender harvest.
Care
Plant in full sun in lean to average, well-drained soil; once established it handles dry spells with little extra water. Hardy in zones 3-8. Shear the plant back by about a third after the first big flush of bloom to tidy it and push a fresh round of flowers.
