Salvia elegans (pineapple sage) is a tender perennial grown for its sweetly pineapple-scented leaves and its showy late-season flower spikes. In warm climates it returns from the roots after winter, then quickly grows into a leafy, upright plant about 24-36 inches tall, with a rounded, bushy habit that can fill a generous space.
Give your plant a sunny spot for the best growth and bloom, and aim for evenly moist, well-drained soil. Water deeply when the top inch or two of soil dries, especially during hot spells. In very hot regions, a little afternoon shade can help the foliage stay lush, but keep the plant in bright light so it flowers well. Pinching or light pruning early in the season encourages branching and more flower stems later.
In late summer through fall, Salvia elegans sends up spikes of tubular red blooms that are a magnet for hummingbirds. After flowering, trim spent stems to keep the plant tidy. When frost arrives, the top growth usually dies back; in mild areas you can cut stems down and mulch lightly to protect the crown. In colder regions, grow it as an annual or overwinter it in a container indoors in bright light.
