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

Meet Bolander’s mock dandelion (Phalacroseris bolanderi var. bolanderi), one of California’s lesser-known native wildflowers that deserves a spot in the conversation about supporting local ecosystems. While you might not find this perennial herb at your typical garden center, understanding rare natives like this one helps us appreciate the incredible diversity hiding in our Golden State landscapes.

What Makes This Plant Special?

Bolander’s mock dandelion is a perennial forb—basically a soft-stemmed flowering plant that comes back year after year without developing woody tissue like shrubs or trees. As a member of the sunflower family, it shares some characteristics with its more famous dandelion relatives, though it’s got its own unique California charm.

This native herb has perennating buds that rest at or below ground level, helping it survive through tough seasons and emerge again when conditions are right. It’s the kind of plant that knows how to work with California’s natural rhythms rather than against them.

Where You’ll Find It

Bolander’s mock dandelion calls California home and is found nowhere else in the world. This makes it a true California endemic—a plant that evolved specifically to thrive in our unique Mediterranean climate and diverse landscapes.

The Rarity Factor: Why This Matters

Here’s something important to know: Bolander’s mock dandelion has a conservation status of S3S4T3?, which means it’s considered uncommon to rare in its native range. This isn’t a plant you’ll stumble across on every hiking trail, and that rarity makes it all the more precious to California’s native plant communities.

If you’re interested in growing this species, it’s crucial to source seeds or plants only from reputable native plant nurseries that practice ethical collection methods. Never collect from wild populations—these rare natives need every individual they can get to maintain healthy populations in their natural habitats.

Garden Potential and Growing Considerations

While specific growing requirements for this particular variety aren’t well-documented (which is often the case with rare natives), we do know it’s adapted to California’s climate patterns. As a native perennial, it would likely thrive in gardens designed to support local wildlife and reduce water usage.

Most California native forbs prefer:

  • Well-draining soils
  • Seasonal watering patterns that mimic natural rainfall
  • Full sun to partial shade
  • Minimal summer water once established

Supporting Biodiversity in Your Garden

Even if you can’t get your hands on Bolander’s mock dandelion specifically, you can still support California’s native plant communities by choosing other native forbs and wildflowers for your garden. Consider more readily available natives like California poppies, lupines, or penstemons that provide similar ecosystem benefits and are easier to source responsibly.

Every native plant we grow helps support the complex web of relationships between plants, pollinators, and wildlife that make California’s ecosystems so special. While we may not all be able to grow rare species like Bolander’s mock dandelion, we can all do our part by choosing natives that fit our specific garden conditions and are sustainably available.

The Bottom Line

Bolander’s mock dandelion represents the incredible diversity of California’s native flora, even if it’s not a plant most of us will grow in our gardens. Understanding and appreciating rare natives like this one reminds us why supporting native plant conservation—through our plant choices, garden practices, and support of conservation organizations—matters so much for preserving California’s natural heritage for future generations.
