Bulbs and Tubers

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.

Allium cernuum, nodding onion, nodding umbels of pink bell-shaped flowers
Wild Nodding Onion
Allium cernuumWild Nodding Onion

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.
