Salvia guaranitica (Anise-scented Sage)
This brilliantly colored, true blue Salvia guaranitica, with anise-scented leaves (when crushed), grows to at least five feet and, although some sources say it is not for any zone below Zone 7, it has been in my Zone 6 garden for many years. Salvia guaranitica is a little slow to pop up in spring, but once it does, you're all set for color until frost because it is an unrelenting rebloomer. Salvia guaranitica makes its presence known not just in constant color and height, but it spreads to make a large patch, easily divided. Salvia guaranitica makes lovely, long-lasting cut flowers if the stems are cut first under water. Sun/part shade, moist, well-drained soil in Zones 6-9. Quarts.
