Spider lily (Lycoris radiata, pictured) and surprise lily, also known as naked lady (Lycoris squamigera), send up foliage in the fall, which remains through spring, and then disappears. In August and September, spikes of flowers standing anywhere from 18-30 inches tall appear seemingly overnight without leaves. Spider lily has bright red glowers with long stamens that resemble spider legs. Surprise lily has pink, trumpet-shaped flowers. Both are easy to grow, spread into drifts, and last for generations. Bulbs are usually available by late spring. Order from oldhousegardens.com.
