Morefield’s Cinquefoil: A Rare California Treasure Worth Protecting
Meet Morefield’s cinquefoil (Potentilla morefieldii), one of California’s most precious and endangered wildflowers. This tiny perennial holds a special place in the Golden State’s botanical heritage, though you’re unlikely to stumble across it during your weekend hiking adventures—and that’s exactly why it deserves our attention and protection.





A True California Native with a Story to Tell
Morefield’s cinquefoil is a native son of California, found nowhere else in the world. This herbaceous perennial belongs to the rose family and represents one of nature’s most exclusive clubs—plants so rare that botanists get genuinely excited when they spot one in the wild.
Currently, this little champion calls only California home, clinging to existence in a handful of mountainous locations. The plant’s entire known range is concentrated in very specific habitats within the state, making it a true California endemic.
Why This Plant Matters (And Why You Probably Shouldn’t Grow It)
Here’s where we need to have a serious conversation. Morefield’s cinquefoil carries a Global Conservation Status of S2, which translates to Imperiled. In plain English? This plant is in trouble—big trouble. Scientists estimate there are only 6 to 20 known populations remaining, with perhaps 1,000 to 3,000 individual plants left in the entire world.
While the gardener in you might be thinking I want to help by growing this rare beauty, the reality is more complex. Growing imperiled species without proper sourcing can actually harm wild populations if seeds or plants are collected from already stressed natural areas.
What Makes This Cinquefoil Special
As a member of the Potentilla genus, Morefield’s cinquefoil shares characteristics with its more common cousins—it’s a low-growing perennial forb (that’s botanist-speak for a soft-stemmed, non-woody plant). Like other cinquefoils, it likely produces small, cheerful flowers that would charm any wildflower enthusiast.
The plant’s herbaceous nature means it dies back to the ground each winter, emerging fresh each spring from its perennial root system—assuming its delicate habitat remains undisturbed.
A Better Way to Support Native Plants
Instead of seeking out this rare treasure for your garden, consider these alternatives that will give you the cinquefoil experience while supporting conservation:
- Plant other native California Potentilla species that are more common and readily available
- Support organizations working to protect rare plant habitats
- Choose native plants that provide similar ecological benefits without conservation concerns
- If you’re a serious native plant enthusiast, work with botanical gardens or conservation groups that may have legitimate propagation programs
The Takeaway
Morefield’s cinquefoil represents something precious in our natural world—a plant so specialized and rare that its very existence is a reminder of nature’s incredible diversity and fragility. While we can’t recommend adding this imperiled species to your garden, we can appreciate its story and use it as inspiration to choose other native California plants that will thrive in cultivation.
Sometimes the best way to love a plant is to leave it alone and protect the places where it belongs. In the case of Morefield’s cinquefoil, that means supporting habitat conservation and choosing abundant native alternatives that can bring the beauty of California’s wildflowers to your own backyard—without putting rare species at risk.
