Harvest Brodiaea

The Harvest Brodiaea (Brodiaea coronaria, also grown as B. elegans) is a jewel of the summer meadow — graceful, vase-shaped violet-blue flowers that open after most spring wildflowers have faded, rising from a sweet, edible corm.^2, 4

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

Edible & Medicinal Uses

Beneath the flowers sits a starchy corm (a solid stem-base, not a layered bulb) that is one of the sweetest and most flavorful native foods — in our experience rivaling camas and wapato. Cooked, the corms have the taste and texture of a sweet potato, and unlike camas they're mild and easy to prepare. Foragers and gardeners have long valued brodiaea corms, dug in late summer once the plant has died back — and replanting the little offset "cormels" keeps the patch going.^1, 4

Ornamental Qualities

Delicate and sky-colored, Harvest Brodiaea holds clusters of violet-blue, vase-shaped flowers atop slender stems over grassy leaves, spreading by cormels into low patches that bloom in early-to-mid summer after other wildflowers rest. It's charming in a rockery, meadow, or the front of a border, and lovely with Nodding Onion and the native lilies.¹

Environment & Culture

Ecology: Native to open, lowland meadows and open woodlands of the West, Harvest Brodiaea is drought-tolerant and summer-dormant, blooming in the dry season and providing late nectar for pollinators. In the wild it grows among camas and wild onion.^1, 4

Culture: Its sweet corms are a valued traditional food, dug in season and stewarded by replanting cormels. 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

Dig the corms in late summer after the leaves have withered, keeping the tiny cormels to replant. Roast or boil them until tender — sweet and smooth, like a little chestnut-sweet-potato — and enjoy as a delicate native root vegetable. Because each plant yields a modest corm, they're a special treat rather than a staple. (Growing and harvest details are on the Planting Guide tab.)
