Immensely showy perennial that puts on a stellar mid summer show of soft blue relatively large flowers. Spreading to 2′ wide in full sun and rich well drained soil this mint relative sends 18″ spikes of outward facing light blue tubular flowers in June-July. Loved by pollinators and gardeners alike. Easy to grow plant that is cold hardy and long lived. Great for blazing hot hellstrips, sunny rock gardens, the front of borders. Light summer water- becomes surprisingly drought tolerant with age. Completely winter deciduous.
