Many years ago I enjoyed growing different types of culinary salvias (sage is salvia officinalis), primarily for ornamental purpose. I never harvested the leaves for cooking.
Now I only grow the flowering ones. Salvia flowers come in many colors and this year I have them in red, blue, salmon and white
The one with the white flowers is the tallest and healthiest. Salvias are annuals for our zone.
Salvias belong in the mint family ( Lamiaceae ), with more than 1000 species, hybrids and cultivars.
According to Wikipedia, the word salvia came from salvere, a Latin word means "to save" referring to its long-believed healing properties.
Salvia prefers a sunny area and well-drained soil. It requires very little maintenance.
