Bolander’s Mock Dandelion: A Rare California Native Worth Protecting

Meet Bolander’s mock dandelion (Phalacroseris bolanderi var. coronata), a fascinating little California native that’s as elusive as it is intriguing. This perennial herb belongs to that special category of plants that makes botanists get a little excited—it’s rare, it’s native, and it’s got a quirky name that sounds like it should be in a fairy tale.

What Makes This Plant Special?

Bolander’s mock dandelion is a true California original, found exclusively within the Golden State’s borders. As a perennial forb (that’s botanist-speak for a non-woody flowering plant), it returns year after year, forming part of California’s precious native plant heritage. Unlike its common dandelion cousins that pop up everywhere, this mock dandelion has chosen to be much more selective about where it calls home.

The Rarity Factor: Why This Matters

Here’s where things get serious for a moment. Bolander’s mock dandelion carries a conservation status that should make any gardener pause and think. With its rarity designation, this isn’t a plant you’ll find at your local garden center, and that’s probably for the best. In the wild, every population of this species counts toward maintaining California’s biodiversity.

Should You Grow Bolander’s Mock Dandelion?

The short answer is: only if you can source it responsibly. If you’re lucky enough to come across seeds or plants from legitimate conservation sources or specialized native plant sales, then you might consider adding this rare beauty to your collection. However, never collect seeds or plants from wild populations—that could harm already vulnerable communities of this species.

What We Know About Growing It

Here’s where we hit a bit of a wall—specific cultivation information for Bolander’s mock dandelion is about as rare as the plant itself. What we do know is that as a California native perennial herb, it likely appreciates:

  • Well-draining soil (most California natives do)
  • Minimal summer water once established
  • A sunny to partially sunny location
  • Patience—rare plants often have their own timeline

The Bottom Line for Native Plant Enthusiasts

Bolander’s mock dandelion represents something precious in the native plant world—a species that reminds us why conservation matters. While you probably won’t be adding this one to your garden anytime soon, knowing about it connects you to California’s incredible plant diversity.

If you’re drawn to rare California natives, consider supporting local native plant societies and botanical gardens that work to preserve species like this one. Sometimes the most important thing we can do as gardeners is simply appreciate these plants where they belong—in their native habitats, doing what they’ve done for thousands of years.

And who knows? Maybe someday, through careful conservation efforts, Bolander’s mock dandelion might become a little less rare and a little more accessible to gardeners who want to grow a truly unique piece of California’s natural heritage.
