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.

Tulbaghia violacea, the plant gardeners know as society garlic, is a clump-forming perennial from the summer-dry grasslands of southern Africa, ranging from the Little Karoo through the Eastern Cape to KwaZulu-Natal. The genus honors Ryk Tulbagh, the eighteenth-century Dutch governor of the Cape of Good Hope, while the species name violacea simply means violet, for the color of the flowers. The common name is a small joke: the leaves carry a clear garlic scent, but a gentler, more sociable one than true garlic, said to be polite enough for company.
