If you're a salvia fan, 'Black and Blue' Salvia is a must-have for your sunny summer garden. Fast-growing, tall (three to four feet), and eye-catching with cobalt blue flowers on black stems, this variety makes quite a statement along borders, in mass plantings, or in large container planters. Startling blue flowers along tall black stems are perfect for attracting bees, butterflies, and hummingbirds, but its fragrant foliage makes it unappealing to deer. Drought tolerant once established, 'Black and Blue' salvia should return each year, but prolonged or extreme cold may kill it. Consider growing this beauty in a large container that can be sheltered under the eaves in winter. Prune back 'Black and Blue' salvia in late winter or early spring before new growth emerges.
