The Mystery of Vicia cracca incana: When Plant Names Get Confusing
If you’ve stumbled across the name Vicia cracca incana in your gardening research, you might be scratching your head trying to find reliable information about this plant. Don’t worry – you’re not alone in your confusion! This particular plant name sits in that tricky territory where botanical nomenclature gets a bit murky.
What’s in a Name?
Vicia cracca incana appears to be a taxonomically uncertain name that may reference characteristics of related vetch species rather than being a distinct plant variety. The botanical world sometimes includes names that are synonyms, outdated classifications, or regional variations that don’t represent current accepted taxonomy.
The synonym Vicia incana Gouan suggests a connection to what we now know as Hoary Vetch (Vicia villosa), while the cracca portion connects to Tufted Vetch (Vicia cracca). Both of these are well-documented species with their own distinct characteristics.
The Vetch Family: Better-Known Relatives
Instead of chasing after this elusive name, let’s talk about the vetch species that are well-understood and available to gardeners:
- Tufted Vetch (Vicia cracca) – A climbing perennial with purple flower spikes
- Hairy Vetch (Vicia villosa) – An annual with purple and white flowers, excellent for cover cropping
- American Vetch (Vicia americana) – A native North American species perfect for wildlife gardens
Why This Matters for Your Garden
When you encounter unclear plant names like Vicia cracca incana, it’s important to verify the identity before making gardening decisions. Here’s why:
- You want to ensure you’re getting the plant characteristics you expect
- Growing conditions and care requirements vary between species
- Native vs. non-native status affects ecological impact
- Some vetches can be aggressive spreaders in certain climates
What Should You Do?
If you’re interested in growing vetches in your garden, I recommend focusing on the well-documented species instead. Choose based on your specific needs:
- For native plant gardens: Look into American Vetch or other species native to your region

Rather than getting tangled up in taxonomic uncertainties, focus on choosing a clearly identified vetch species that matches your gardening goals and local growing conditions.
Remember: when in doubt about a plant name, consult with your local extension office or native plant society. They can help you identify the best vetch varieties for your specific location and gardening objectives.
