Fool's Onion

Fool's Onion (Triteleia hyacinthina), also called White Brodiaea or Wild Hyacinth, is a lovely white-flowered wildflower of Northwest prairies with a sweet, edible corm — and, despite its name, no relation to the onion.^2, 4

NOTE: Native wildflowers are dormant (no leaves/flowers) Summer–Fall.

Edible & Medicinal Uses

The name is a gentle joke: Fool's Onion looks like a wild onion but has none of the onion smell or taste. Its round corm is instead mild and sweet — closer to a little new potato — and delicious eaten raw or, better, cooked (boiling or roasting removes any slight acridity and brings up the sweetness). It's long gathered and pit-cooked as a wild food. WARNING: In the wild, Fool's Onion can be confused with the toxic death camas — and because it has no onion smell, the sniff test that identifies true wild onions does not work here. Never wild-harvest without expert identification; our labeled nursery plants let you enjoy it safely.^1, 4

Ornamental Qualities

Elegant and long-blooming, Fool's Onion carries rounded clusters of up to 40 star-shaped, milky-white flowers (each with a fine green midvein, sometimes lavender-tinged) atop slender 1–2 ft stems in late spring, after other bulbs fade. A favorite of bees and butterflies and a fine cut flower, it's beautiful drifted with Common Camas, Nodding Onion, and Harvest Brodiaea.^1, 4

Environment & Culture

Ecology: Native from British Columbia to California, Fool's Onion grows in open prairies, meadows, and vernally moist ground, often in Garry oak country among camas and wild onion. It's drought-tolerant and summer-dormant, its late bloom feeding pollinators.^1, 4

Culture: The corm is a traditional food gathered and cooked by many nations — among them the Maidu, Pomo, Miwok, Washoe, and Paiute — and coastal First Nations continue to use it. We offer it with respect for that living knowledge and invite support for Indigenous-led restoration through our Charitable Giving page.⁴

In the Kitchen

Rinse the thin-skinned corms and boil them about ten minutes, or roast them, until tender — mild, sweet, and pleasantly potato-like, good with butter and salt or added to a soup. Don't expect onion flavor; think of it as a tiny sweet potato instead. (Growing and harvest details are on the Planting Guide tab.)⁵
