Salvia is a large group of plants that includes the culinary sage as well as many that are grown as bedding annuals. This one is a perennial, forming a bushy mound of fuzzy olive-green leaves. Upright spikes of violet-purple flowers begin to appear in early summer, and will continue for weeks if the spent heads are regularly removed. It tolerates many soil conditions, and is drought tolerant, once established. A nice choice for the border, low enough to use for edging. If plants become floppy in mid summer they should be clipped back hard to rejuvenate the foliage.
