There are hundreds of species of salvia. In fact, the herb we know as sage is a type of salvia, and is classified not only as an herb, but a flower as well. The red salvia is the one that most people are familiar with, but it is also available in shades of purple, pink and white. It can grow in height anywhere from 10 inches up to 3 feet or more, and will produce flowers throughout the summer.
Salvia is available as an annual in colder climates and should be planted after the last frost. Established plants can be purchased at most garden centers. Select a sunny location with soil that drains well. They should be set into the ground at the same depth as their dirt enclosure. Space them 8-10 inches apart depending on the variety (dwarf types such as the Vista would need less room than some of the taller varieties). Water well. As the blossoms fade, pinch them off so that the plant will be able to spend its energy producing more flowers.
