Cleveland’s Spineflower: A Delicate Native Annual Worth Growing
If you’re looking to add a touch of delicate beauty to your Southern California native garden, Cleveland’s spineflower (Chorizanthe clevelandii) might just be the charming little annual you’ve been searching for. This unassuming native forb may not win any contests for showiness, but what it lacks in drama, it makes up for in ecological value and understated elegance.

Don’t let the word spineflower intimidate you – while the plant does have tiny spines on its flower bracts, they’re more decorative than dangerous.
This native beauty is found exclusively in California, making it a true local treasure for Golden State gardeners. However, it’s worth noting that Cleveland’s spineflower has a Global Conservation Status of S3?, indicating it may be vulnerable or rare in some areas. This makes it all the more important to grow it responsibly using ethically sourced seeds.

- Watering: Provide moderate water during germination, then reduce significantly once established
- Fertilization: None needed – native soils provide adequate nutrition
- Maintenance: Minimal pruning required; allow plants to set seed for next year’s crop
Remember, since this plant has a potentially vulnerable conservation status, always source seeds from reputable native plant nurseries or seed companies that collect responsibly. Never collect seeds from wild populations.
Wildlife and Pollinator Benefits
Despite its small stature, Cleveland’s spineflower punches above its weight when it comes to supporting local wildlife. The tiny flowers attract a variety of beneficial insects, including small native bees, beneficial wasps, and other pollinators. These insects, in turn, support birds and other wildlife up the food chain.
