'Caradonna' Sage (Salvia nemerosa 'Caradonna') is a sport, or mutant, of the 'Wesuve' variety of sage. It turned up as a seedling in Germany and in 2000 was named the Outstanding New Perennial by the International Hardy Plant Union. The plant is prized especially for its 2-foot-tall, blue-violet flower spikes. The plant also has velvety light green foliage and purple stems and forms a mound 12 inches tall by 18 inches wide. It does beautifully in the Ozarks.
