Tehachapi Woollystar: A Rare California Native Worth Growing
If you’re looking to add a touch of silvery magic to your California native garden, the Tehachapi woollystar (Eriastrum pluriflorum) might just be the hidden gem you’ve been searching for. This charming annual wildflower brings a unique woolly texture and delicate blooms that make it stand out from the crowd of more common native plants.
What Makes Tehachapi Woollystar Special?
The Tehachapi woollystar is a true California original, endemic to the Golden State and specifically associated with the Tehachapi Mountains and surrounding areas of the southern Sierra Nevada. As an annual forb, this herbaceous plant completes its entire life cycle in one growing season, making it a dynamic addition to gardens that change with the seasons.
What really sets this plant apart is its distinctive appearance. The silvery-gray foliage has a wonderfully fuzzy, woolly texture that gives the plant its common name. Come blooming season, small star-shaped flowers in white to pale blue appear in rounded, clustered heads, creating a charming contrast against the soft, gray foliage.
A Word About Rarity
Before we dive into growing tips, it’s important to note that Tehachapi woollystar has a Global Conservation Status of S3?, indicating some level of rarity and uncertain population status. This means that if you’re interested in growing this beautiful native, you should only source seeds or plants from reputable native plant nurseries that practice responsible collection methods. Never collect seeds from wild populations.

Growing Conditions and Care
