This vigorous growing perennial reaches 1'-1.5' tall and spreads 2'. It will reseed and spread if spent flowers are NOT removed. Foliage is fragrant when brushed (ask any cat), with scalloped edges and covered with fine hairs. Beautiful violet blue, 2 lipped flowers bloom in summer and fall. This plant tolerates full to part sun with well draining, dry soil. Low to moderate water once it's established.
