Hickman’s Popcornflower: A Rare California Native Worth Protecting in Your Garden
If you’re passionate about California native plants and conservation, Hickman’s popcornflower (Plagiobothrys chorisianus var. hickmanii) might just capture your heart. This delicate annual wildflower is a true California treasure, though finding it for your garden requires some extra care and consideration.
What Makes This Plant Special
Hickman’s popcornflower is an enchanting little annual that belongs to the borage family. True to its common name, this forb produces clusters of tiny white flowers that do indeed resemble miniature popcorn kernels when they’re in bud. The flowers unfurl along coiled stems in a characteristic pattern that’s both charming and distinctive.
As a herbaceous annual, this plant completes its entire life cycle in one growing season, making it perfect for adding seasonal interest to native plant gardens and naturalized landscapes.
Where It Calls Home
This special variety is endemic to California, meaning it grows naturally nowhere else in the world. You’ll find it in coastal areas and seasonal wetlands throughout the Golden State, where it has adapted to the Mediterranean climate patterns of wet winters and dry summers.
Important Conservation Note
Here’s where things get serious: Hickman’s popcornflower has a conservation status of S3T3Q, which indicates it’s considered rare and potentially vulnerable. This means that while it’s absolutely worth growing, you should only plant it using seeds or plants from reputable native plant nurseries that source their material responsibly. Never collect from wild populations!
