Appearance
''Salvia verticillata'' has a leafy base of mid-green leaves covered with hairs, putting up leaf-covered stems that carry 3 feet inflorescences. The tiny lavender flowers grow tightly packed in whorls, with tiny lime-green and purple calyces. The specific epithet ''verticillata'' refers to the whorls that grow in verticils. A cultivar introduced in the 1990s, 'Purple Rain', is much more showy and long-blooming, growing about 2 feet tall.Naming
