Brodiaea
A group of corm-growing lily-like flowers from western North America
Brodiaea is a genus of herbaceous perennial plants that grow from corms and produce clusters of blue to purple flowers on leafless stems. Native to the Pacific coast of North America, especially California, they bloom in early summer and are sometimes grown in gardens or dried for decoration.
- Grows from a corm and blooms in early summer
- Flowers appear in rounded clusters on bare stems
- Most species are found only in California
- Scientific name Brodiaea is officially conserved
- Some species are endangered due to limited habitat
What does Brodiaea look like?
Brodiaea plants grow from underground corms and send up narrow leaves close to the ground. Their bare flowering stalks hold clusters of flowers called umbels. Each flower has six petal-like parts that are blue or purple, fused at the base into a short tube with spreading tips. Inside, there are three regular stamens and three sterile ones that look like tiny petals.
Where does Brodiaea come from?
First collected near the Strait of Georgia in 1792 by Archibald Menzies, Brodiaea was later named by James Edward Smith in 1810 after Scottish botanist James Brodie. An earlier name, Hookera, was set aside to avoid confusion with a moss genus, making Brodiaea a conserved scientific name. The plants are native only to western North America.
When and how Brodiaea blooms
These perennials emerge from corms each year. They form a few slender leaves and then send up smooth, leafless stems topped with rounded clusters of flowers. They thrive in sunny spots and often grow in soils with unusual chemistry, such as serpentine. Some species flower in early summer, later than many spring bulbs.
How Brodiaea is used
Gardeners plant Brodiaea species like B. californica and B. coronaria for their late-spring to early-summer blooms. The larger flower heads can be dried and kept as winter decorations. Smaller kinds are suited to bulb frames or alpine houses, where their delicate forms can be appreciated up close.
Kinds of Brodiaea
The genus includes about 18 accepted species, most found only in California. Brodiaea pallida, for example, survives in just two locations on the Tuolumne–Calaveras county line. Plants once placed here, such as those now in Dichelostemma and Triteleia, are no longer considered true Brodiaea.
What Brodiaea means
Brodiaea’s scientific name was the subject of an early botanical dispute, resolved by conserving Smith’s name over Salisbury’s Hookera. Several species are rare due to their restricted habitats, especially on serpentine soils. Though not tied to festivals or faiths, they are valued in native plant gardening and conservation.
