Blue Sage (Salvia azurea)

Blue Sage (Salvia azurea), also known as azure blue sage, is a tall, native perennial admired for its sky-blue flower spikes and graceful, airy habit. This late-summer bloomer adds soft color, refined texture, and an eye-catching focal point to meadows, naturalized plantings, and pollinator-friendly landscapes.

Distinctive Features

'Salvia azurea' features long, slender stems that produce masses of soft, sky-blue flowers from late summer into fall. The airy, open habit reaches 3 to 5 feet tall, creating graceful movement in garden beds. Its nectar-rich blooms are highly attractive to bees, butterflies, and hummingbirds, while the seed heads provide food for birds in fall and winter. The narrow, lance-shaped foliage offers a delicate, textural backdrop to the bright blooms, making it an excellent companion plant in native and naturalized settings.
