Most likely you have heard about the nitrogen trapping ability of legumes like peas and beans when it comes to our edible gardens. Did you know that there are also lovely perennial legumes that we can add to our ornamental beds to help harvest the nitrogen for other plants? I just planted two false indigo plants in front of a ‘Gertrude Jekyll’ rose in an ornamental bad I’m adding up the garage.
Not only do these plants look lovely, they will help all the plants around them, especially if I cut back some of the foliage and use it as mulch. If you haven’t noticed the root nodules on these types of plants look at this.
There are so many nitrogen fixing perennials, shrubs and trees it pays to incorporate them into our ornamental beds. I spotted these lupines on my garden tour this past weekend and I have a few growing in my garden as well. They will pair perfectly with peonies since they bloom at the same time.
From crimson clover to locust trees you can find nitrogen fixing plants in all shapes, colors, sizes, and for all climates. If you don’t have any perennial legume family plants in your garden consider adding them. Of course you will want to check and make sure the ones you want to use won’t become invasive in your area before adding them to your garden.
Whenever you can use plants to increase the fertility in your soil you save time, money, and resources.
