Gallon plant of Salvia mexicana Limelight. This unusual tender perennial displays a very bright neon color combination when its vibrant purple-blue flowers open from the bright chartreuse-colored calyx. Glossy, bright green leaves hold their own until the show gets started in August and continues until frost. It forms a tall bush, 6 feet tall by 6 feet wide, especially good for the back of the border. Salvias are some of the showiest plants for containers, annual borders, and mixed borders. Butterflies and hummingbirds love them. Hardy in zones 8-10.
