Clifford’s Phacelia: A Critically Rare Arizona Native Worth Protecting
If you’re a native plant enthusiast with a passion for rare botanical treasures, you might have stumbled across the name Clifford’s phacelia (Phacelia cliffordii). This diminutive desert annual represents one of Arizona’s most imperiled plant species, and its story is both fascinating and sobering for anyone interested in native plant conservation.
What Makes Clifford’s Phacelia Special?
Clifford’s phacelia is an annual forb – essentially a non-woody flowering plant that completes its entire life cycle in a single growing season. As a member of the waterleaf family (Hydrophyllaceae), it shares lineage with other beloved native phacelias that gardeners often seek out for their pollinator appeal and delicate beauty.
This particular species is what botanists call a forb, meaning it’s a vascular plant without significant woody tissue above ground. Like other annual wildflowers, it emerges, blooms, sets seed, and completes its cycle within one year, likely timing its growth to coincide with Arizona’s favorable weather patterns.
Where Does It Call Home?
Clifford’s phacelia is exclusively native to Arizona, making it a true endemic species. This means you won’t find it growing naturally anywhere else in the world – Arizona is its one and only home.
The Conservation Reality
Here’s where the story takes a serious turn. Clifford’s phacelia carries a Global Conservation Status of S1, which translates to Critically Imperiled. This designation means the species faces extreme rarity, typically with five or fewer known occurrences or very few remaining individuals (fewer than 1,000 plants total).
For gardeners, this presents an important ethical consideration. While we might be tempted to seek out and grow rare native plants, species like Clifford’s phacelia require a different approach entirely.
Should You Plant Clifford’s Phacelia?
The short answer is: probably not, and here’s why. With such critically low numbers in the wild, any seeds or plants available through commercial channels would either be:
- Illegally or unethically collected from wild populations (which could harm the species’ survival)
- So rare that they’re not available through any responsible sources
- Potentially requiring specialized growing conditions that aren’t well-documented due to limited research
Instead of trying to grow this rare gem, consider these more responsible approaches:
How You Can Help Instead
Rather than attempting cultivation, here are meaningful ways to support Clifford’s phacelia and similar rare species:
- Support conservation organizations working to protect Arizona’s rare plants and their habitats
- Choose abundant native alternatives like other phacelia species that provide similar ecological benefits without conservation concerns
- Practice habitat preservation by supporting land protection efforts in Arizona
- Spread awareness about rare plant conservation needs
Better Phacelia Alternatives for Your Garden
If you’re drawn to the phacelia family, consider these more common and garden-appropriate native species:
- Desert bluebells (Phacelia campanularia) – stunning blue flowers
- Parry’s phacelia (Phacelia parryi) – excellent for desert gardens
- Fernleaf phacelia (Phacelia distans) – delicate, fern-like foliage
These alternatives can provide the beauty and ecological benefits you’re seeking while leaving critically imperiled species like Clifford’s phacelia to recover in their natural habitats.
The Bigger Picture
Clifford’s phacelia serves as a reminder that not every native plant belongs in our gardens – sometimes the best thing we can do for a species is to admire it from afar and work to protect its wild habitat. By choosing abundant native alternatives and supporting conservation efforts, we can create beautiful, ecologically valuable gardens while helping ensure that rare treasures like Clifford’s phacelia have a chance to persist for future generations.
After all, the ultimate goal of native gardening isn’t just about what we can grow, but about fostering a deeper connection with and responsibility toward the natural world around us.
