Alverjilla (Adesmia bicolor): A Mysterious South American Native
If you’ve stumbled upon the name alverjilla or its botanical moniker Adesmia bicolor while researching native plants, you’re in for a bit of a mystery. This South American species, also known as babosita patope, belongs to the fascinating Adesmia genus – but finding detailed information about this particular species is like searching for a needle in a haystack.

What We Know About Alverjilla
Adesmia bicolor is part of the legume family (Fabaceae), which means it’s related to familiar plants like beans, peas, and clover. The Adesmia genus is native to South America, particularly thriving in the diverse ecosystems of Argentina, Chile, and neighboring regions. These plants have adapted to some pretty tough conditions, from high-altitude environments to arid landscapes.
The Information Challenge
Here’s where things get tricky – while we know alverjilla exists as a species name, detailed information about its specific characteristics, growing requirements, and garden applications is surprisingly scarce in reliable botanical sources. This could mean several things:
- It might be an extremely rare or localized species
- It could be a regional common name that doesn’t correspond to widely recognized botanical records
- The species might be known by other scientific names in different regions
- It may have very limited cultivation history outside its native range
What This Means for Gardeners
If you’re considering adding alverjilla to your garden, you’ll want to proceed with caution. Without reliable information about its growth habits, hardiness zones, invasive potential, or care requirements, it’s difficult to make informed gardening decisions.
Better Alternatives to Consider
Instead of chasing this elusive species, consider exploring other well-documented Adesmia species or similar legumes that are better understood and more readily available:
- Look into other South American native legumes that are better documented
- Consider native alternatives from your own region
- Explore established Adesmia species with known cultivation requirements
If You Encounter This Plant
Should you come across what’s labeled as Adesmia bicolor or alverjilla, approach with curiosity but caution. Take photos, note the location, and consider reaching out to local botanists or native plant societies. You might be looking at something quite special – or you might help solve a naming puzzle.
The Takeaway
While alverjilla remains something of an enigma in the gardening world, this highlights an important point about native plant gardening: not every species name you encounter will have readily available growing information. Sometimes the most responsible approach is to stick with well-documented natives that you can grow successfully and sustainably.
Remember, the best native garden is one filled with plants you can actually keep alive and thriving – and that means choosing species with clear growing guidelines and reliable sources.
