Mojave Tarweed: A Rare Desert Gem for Your Native Garden
Meet Mojave tarweed (Deinandra mohavensis), a charming little annual that brings the wild beauty of California’s Mojave Desert right to your garden. This unassuming native herb might not win any height contests, but what it lacks in stature, it more than makes up for in desert toughness and ecological value.

What Makes Mojave Tarweed Special?
Mojave tarweed is a true California native, belonging to the sunflower family and perfectly adapted to life in some of the state’s most challenging environments. As an annual forb, this herbaceous plant completes its entire life cycle in one growing season, making the most of brief favorable conditions in the desert.
You might also see this plant listed under its scientific synonym, Hemizonia mohavensis, in older gardening references, but Deinandra mohavensis is the current accepted name.
Where Does It Grow Wild?
This desert specialist calls California home, specifically thriving in the Mojave Desert region. You’ll find wild populations growing in sandy washes, desert flats, and other well-draining locations where few other plants dare to venture.
Important Conservation Note
Before you rush to add Mojave tarweed to your garden, there’s something crucial to know: this plant has a conservation status of S2S3, meaning it’s considered rare to uncommon in its native range. While we absolutely encourage growing this beautiful native, please only use seeds or plants from responsible, ethical sources that don’t impact wild populations. Never collect from the wild!

Growing Conditions and Care
Think desert tough and you’ll understand exactly what Mojave tarweed needs to thrive:
Sunlight: Full sun is essential – this plant has zero tolerance for shade

- Maintenance: Allow plants to self-seed for natural population renewal
- Fertilizer: None needed – desert plants prefer lean conditions
