Fourpart Phacelia: A Delicate Native Wildflower for Western Gardens
If you’re looking for a charming native wildflower that asks for little but gives back plenty, let me introduce you to fourpart phacelia (Phacelia tetramera). This humble annual might not steal the spotlight like showier perennials, but it has a quiet beauty that makes it a wonderful addition to natural gardens throughout the western United States.
What is Fourpart Phacelia?
Fourpart phacelia is a native annual forb – essentially a non-woody flowering plant that completes its entire life cycle in one growing season. True to its botanical family, this little wildflower produces the characteristic coiled flower clusters that make Phacelia species so distinctive. The small blue to purple blooms may be delicate, but they pack a punch when it comes to supporting local wildlife.
You might also encounter this plant listed under its synonym Miltitzia pusilla in older botanical references, but Phacelia tetramera is the accepted name today.

As a true western native, fourpart phacelia calls six states home: California, Nevada, Oregon, Utah, Washington, and Wyoming. This wide distribution across diverse western landscapes tells us something important – this is one adaptable little plant!

A Few Things to Keep in Mind
While fourpart phacelia is generally easy-going, here are a few considerations:
- As an annual, you’ll need to replant each year or allow it to self-seed
