The garden's hidden clock. Bulbs and tubers wait out of sight and rise on their own schedule, opening flowers that seem to arrive from nowhere and then retreating underground to wait for the next year.
A graceful native onion, Allium cernuum, the nodding onion, lifts loose clusters of pink to lavender, bell-shaped flowers that bend over in a soft arc at the top of slender stems, swaying through mid and late summer above tufts of grassy, blue-green foliage. The nodding habit gives the plant a particular charm, and the flowers draw native bees, butterflies, and other pollinators in good numbers.

Few native bulbs command a wet margin the way Hymenocallis liriosme does. From a basal fountain of arching, strap-shaped, glossy green leaves rise leafless scapes, each crowned with several large white flowers whose narrow segments splay outward like pale spider legs around a central membranous cup. The fragrance arrives at dusk, sweet and carrying, a signal to the night-flying moths that pollinate the blooms in late spring and early summer.
A native lily that answers the rain. Zephyranthes atamasco, the atamasco lily or rain lily, is a bulbous perennial of the amaryllis family, native to moist woods and meadows of the Southeastern United States. The name atamasco comes from the Powhatan people of the Virginia tidewater, an old word carried into botany, and the plant has also long been called Easter lily for the season of bloom.
