Salvia azurea, commonly called Blue Sage or Azure Sage, is a hardy, drought-tolerant perennial known for its tall spikes of beautiful sky-blue flowers from summer to autumn, attracting pollinators like bees and butterflies with its nectar-rich blooms and providing structure in garden borders, rockeries, or wildflower meadows. It thrives in full sun, well-drained soil, dying back in winter and regenerating in spring.
