Lost Hills Saltbush: A Rare California Native You Shouldn’t Plant (And Here’s Why)
Meet the Lost Hills saltbush (Atriplex vallicola), a little-known annual plant that’s got conservationists and botanists pretty worried. While most gardening articles encourage you to plant native species, this is one rare case where we’re going to pump the brakes and explain why this particular California native should stay off your shopping list.

What Makes Lost Hills Saltbush Special?
Lost Hills saltbush is an annual herb that belongs to the saltbush family, known scientifically as Atriplex vallicola. You might also see it listed under its synonym, Atriplex coronata var. vallicola, in older botanical references. This unassuming plant is native to the lower 48 states, but here’s the kicker – it’s found exclusively in California, making it what botanists call an endemic species.
Where Does It Grow?
This rare saltbush calls California home, specifically areas within the San Joaquin Valley region. Its geographic distribution is extremely limited, which is part of what makes it so special – and so vulnerable.
The Conservation Reality Check
Here’s where things get serious. Lost Hills saltbush has a Global Conservation Status of S2, which translates to Imperiled. In plain English, this means the species is in trouble – typically with only 6 to 20 known occurrences and somewhere between 1,000 to 3,000 individual plants remaining in the wild. That’s not a lot when you’re talking about an entire species!
This imperiled status is why we’re not going to give you growing tips or encourage you to seek out seeds. Instead, we’re asking you to be a conservation hero by leaving this one to the experts.
What Does It Look Like?
Lost Hills saltbush is an annual plant, meaning it completes its entire life cycle in one growing season. Like other members of the saltbush family, it’s adapted to somewhat harsh conditions and can handle alkaline soils that would make other plants throw in the towel.
The plant has a facultative wetland status in both the Arid West and Western Mountains regions, which means it usually hangs out in wetland areas but can occasionally be found in drier spots. This flexibility might seem like it would help the species survive, but unfortunately, habitat loss has still pushed it to the brink.
Why You Shouldn’t Plant It
We know it sounds counterintuitive – after all, isn’t planting native species supposed to be good for the environment? Generally, yes! But when we’re dealing with a species this rare, there are several important reasons to resist the urge:
- Any seeds or plants in cultivation should be reserved for legitimate conservation efforts
- Wild collection could further harm already tiny populations
- The species requires very specific growing conditions that are difficult to replicate
- Conservation efforts are better served by protecting existing habitat rather than scattered garden plantings
Better Alternatives for Your California Garden
If you’re drawn to the idea of growing saltbush species in your California landscape, there are several more common native alternatives that would love a spot in your garden:
- Four O’Clock Saltbush (Atriplex elegans) – an annual with silvery foliage
- Desert Saltbush (Atriplex polycarpa) – a perennial shrub perfect for xeriscaping
- Big Saltbush (Atriplex lentiformis) – a larger shrub great for habitat gardens
How You Can Help
While you can’t grow Lost Hills saltbush in your backyard, there are other ways to support its conservation:
- Support organizations working on California habitat conservation
- Choose other native California plants for your landscape
- Spread awareness about rare plant conservation
- Volunteer with local native plant societies
Sometimes being a responsible gardener means knowing when not to grow something. Lost Hills saltbush is one of those times when the best thing we can do is appreciate it from a distance and let the conservation experts handle its care. Your garden will be just as beautiful – and your conscience just as clear – with some of those hardier saltbush relatives instead!
