List of Nitrogen-Fixing Plants

Grab these Downloads for Quick Reference!

Rhizobia bacteria are primarily responsible for pulling nitrogen out of the air and making it available to plants, which then use the nitrogen to create proteins.

The legume family (the pea & bean family) of plants are able to form a mutually beneficial relationship with rhizobia bacteria. Because of this, growing legumes in your gardens and landscapes can help improve the health of nearby plants through the nitrogen they add to the soil around them.

    Great information!

  2. Andrea October 30, 2014 at 12:54 pm #

    Interesting! I have never read that before. We usually have a few bean plants near our garden. I will have to locate them a little closer next year.

    All your .pdf files are coming up as 404 errors.

      Thank you for letting me know! I’ll fix it asap.

    Still returning 404 error!

      I’m so sorry. Thank you to my readers for being on top of it! I have now fixed them and double-checked them. They should all work now!

    Scarlet Runner Bean is a lovely vine that not only fixes nitrogen but also produces sweet nectar in red pea blooms that attract and feed hummingbirds. A double benefit. I think that the beans are edible but I haven’t tried that yet.

    Please don’t plant invasive species like scotch broom and russian olive. Ask your local master gardeners for advice.

      Great comment. Thank you!

      No Russian Olive is so correct. Our township in Michigan sold them years ago and I assume they did not know just how invasive they are.

      Now they are everywhere! We had to hire a farmer to brush whack them off our property. You can’t hand dig them out…..Our neighbors pasture was taken over by them and now the horses cant use the pasture.

    Do sweet pea flower plants have nitrogen fixing properties?

    • Anni August 30, 2016 at 9:18 pm #

      Yes, they do. They’re in the legume family.

      Which plant, exactly, are you looking for?

  13. Brian February 21, 2017 at 9:49 am #

    Don’t forget to add Goumi to the list of nitrogen fixers. Non-invasive and produces tasty and highly nutritious berries.
