Perennial and annual salvias add so much to the summer and especially the fall garden. They bloom all summer and as the evenings cool when we head into the fall they gain momentum and bloom more and more. Hummingbirds adore all salvias. Some of you may be scorned by the last two winters taking a toll on the greggii and macrophylla varieties, but these plants give so much during the summer and fall months that they are worth it to grow even as a tender perennial. For super hardy salvia, try Salvia reptans, azurea and azurea ‘September Snow’. These gorgeous fall bloomers with sky blue or white flowers are hardy to Zone 5.
