Now here is a plant that herb gardeners can get excited about! Salvia officinalis purpurea, Purple, Sage is a gorgeous variety of the much-loved garden sage. Grown best in a sunny garden with well-drained soil, this sage will feed all of your DIY projects and delicious kitchen recipes for years to come. The delightful purple color that appears on many of the wrinkled leaves adds to its ornamental value in the garden, especially when paired with other gray-leaved plants, like lavender. It can be trimmed, but take care not to cut it back too far.
