It is a tender perennial or subshrub that exhibits a bushy, somewhat open habit with upright, branching, square, dark green stems typically growing 3-5’ tall. When grown as an annual, plant height is shorter, more often in the 2.5-3’ area. Two- lipped, tubular, deep blue flowers (to 2” long) with purple-blue calyxes bloom in axillary and terminal spikes (to 10” long) from mid-summer into fall. Ovate, wrinkled, pointed, lightly-toothed, dark green leaves (2-5” long) are pale green below. Plants may grow to as much as 6’ tall in optimum conditions where winter hardy. Plants are sometimes commonly called blue anise sage or anise scented sage. When bruised, the foliage has a very mild aroma that has very little if any anise scent. ‘Black and Blue’ is a cultivar that features deep cobalt blue flowers with black calyces. Flowers appear on spikes to 15” long over a long mid-summer to fall bloom. Problems No serious insect or disease problems. Susceptible to downy and powdery mildew.
