Colors include pink, rose, lavender or white. A shorter form is C. sulphureus 'Sunny Red' which is quite bushy and tops out at 14 inches or so. Lots of choices when you want to grow Salvias, another hot weather choice. In this one, plant in full sun unless your temperatures are consistently over 90 degrees. With those really high temperatures, they like partial shade.
Flowers are tubular in rings on long spires.
The common name for this plant is sage, so you can find lots under such names as violet sage, scarlet sage, gentian sage, and as Clary sage or meadow clary. Among the easiest to grow and therefore not always appreciated is the Zinnia. Once again lots of choices here. This plant benefits from some judicious mulching to help it retain a little moisture and be sure to dead head regularly. If you do, the plant rewards you with bushy growth and lots of repeat flowers.
