Full to part sun; low water. A handsome long-lived and vigorous plant that forms a compact shrub to 2-3ft tall by just a bit wider. It has fragrant silvery-gray, toothed-edged leaves. The blooms are soft blue lavender in tight whorled spikes on short stems, appearing nearly year-round in mild climates; noted as one of the best for winter flowers. Heat and humidity tolerant.
