Whenever visitors to the nursery ask about hummingbird attractors, we immediately show them all the perennial and annual salvias we carry. 'Rockin Blue Suede Shoes' salvia is a fast-growing annual, topping out around three feet tall and almost as wide, with a profusion of blue tubular flowers on black calyxes, from spring right up to freeze. Use it as the main attraction in container planters, the middle of borders, or as a mass summer planting. Its slightly fragrant leaves seem to be a deer-deterrent and will look its best in a sunny location with regular watering. Consider planting 'Rockin Blue Suede Shoes' near the vegetable garden to attract pollinators or as a spot of color in herb gardens.
