Dotted Onion: A Delicate Native Gem for Western Gardens
If you’re looking to add a touch of understated elegance to your native plant garden, meet the dotted onion (Allium punctum). This charming little perennial might not win any showiest flower contests, but it’s got that quiet beauty that makes native plant enthusiasts swoon. Plus, it’s perfectly adapted to life in the American West, making it a smart choice for gardeners who want to work with nature rather than against it.
What Makes Dotted Onion Special
The dotted onion is a true western native, calling California, Nevada, and Oregon home. As a member of the onion family, it produces delicate clusters of small white to pinkish flowers that seem to float above narrow, grass-like foliage. The dotted in its name refers to subtle markings on the flowers that give this plant its distinctive character.
This perennial forb grows as a herbaceous plant, meaning it doesn’t develop woody stems like shrubs or trees. Instead, it emerges fresh each year from underground bulbs, creating graceful clumps that blend beautifully with other native plants.
