(Radio Red Autumn Sage) Dark calyxes support true red blossoms in Salvia greggii 'Radio Red', a 2015 introduction from the Darwin Perennials division of Ball Seed. Its tiny, smooth, elliptical leaves form a light, airy backdrop for the dramatic flowers.

Well branched, short, compact and long blooming, Radio Red Autumn Sage is an excellent choice for containers or front of border. Although adaptable to many kinds of gardens, this cultivar prefers average watering based on local rainfall.

Radio Red grows well in full sun, but can handle partial shade for part of the day. Deer avoid it, but honeybees and hummingbirds enjoy the nectar and pollen of this vigorous, cold-tolerant perennial.

Western pioneer and plant explorer Josiah Gregg introduced Autumn Sage to horticulture in 1846. He collected it in the Southwest while working as a scout and Spanish interpreter for the U.S. Army during the Mexican-American War.

Although first cultivated in 1885 and a long-time staple in Texas gardens, Salvia greggii didn't show up in plant nurseries until about 100 years later. Now it is one of the most popular species of Salvia for home gardens.
