Bartlettia: The Mysterious Native Annual You’ve Probably Never Heard Of
If you’re looking for a conversation starter in the native plant world, Bartlettia might just be your ticket. This enigmatic little annual is one of those plants that even seasoned botanists might scratch their heads over. Don’t worry if you’ve never encountered it before – you’re definitely not alone!





What Exactly Is Bartlettia?
Bartlettia is a native annual plant that calls the American Southwest home. As an annual, it completes its entire life cycle – from seed to flower to seed again – within a single growing season. This means you’ll need to replant it each year, though if you’re lucky, it might self-seed in the right conditions.
What makes Bartlettia particularly intriguing is just how little we know about it from a gardening perspective. It’s like the botanical equivalent of that indie band your friend keeps talking about – you know it exists, but good luck finding much information about it!
Where Does Bartlettia Call Home?
This mysterious native has a pretty limited range, naturally occurring only in New Mexico and Texas. Its restricted distribution suggests it has very specific habitat requirements that aren’t easily replicated in typical garden settings.
Should You Try Growing Bartlettia?
Here’s where things get tricky. While Bartlettia is undoubtedly a legitimate native plant worthy of conservation, it’s not exactly what you’d call garden-ready. The lack of cultivation information, seeds, or plants available through typical nursery channels makes it more of a botanical curiosity than a practical garden choice.
The Reality Check
If you’re drawn to the idea of growing rare native annuals from the Southwest, you might want to consider these more accessible alternatives:
- Desert marigold (Baileya multiradiata) – a cheerful, drought-tolerant annual
- Ghost plant (Graptopetalum paraguayense) – striking and easy to grow
- Desert lupine (Lupinus sparsiflorus) – beautiful purple spikes that pollinators adore
Growing Conditions (Best Guess)
Based on its native range in New Mexico and Texas, Bartlettia likely prefers:
- Full sun exposure
- Well-draining, sandy or rocky soils
- Minimal water once established
- Hot, dry conditions
- USDA hardiness zones 7-10
The Bottom Line
Bartlettia represents one of those fascinating gaps in our horticultural knowledge. While it’s undoubtedly a legitimate native species deserving of respect and conservation, it’s not currently a viable option for most home gardeners. Sometimes the most interesting plants are the ones that remain wild and mysterious!
If you’re passionate about supporting native plants from the Southwest, focus your energy on the many well-documented species that are readily available and proven garden performers. Your local native plant society or extension office can point you toward natives that will thrive in your specific area while supporting local wildlife.
Who knows? Maybe someday a dedicated botanist will unlock the secrets of successfully cultivating Bartlettia. Until then, it remains one of nature’s beautiful mysteries – and sometimes that’s perfectly okay.
