What significant ecological benefit does Ceanothus americanus provide to the soil as a non-leguminous plant in sunny or partially sunny spots?

Answer

It functions as a nitrogen fixer, as bacteria in its root nodules convert atmospheric nitrogen into a usable form that fertilizes the plant and surrounding soil.

One of the key inherent qualities that makes *Ceanothus americanus* an excellent choice for landscape cultivation, especially in struggling conditions, is its ability to enrich the soil through nitrogen fixation. Although it is classified as a non-leguminous species, its root nodules harbor specific bacteria. These bacteria perform the vital function of converting inert atmospheric nitrogen (N2) into forms that plants can readily absorb and utilize as fertilizer. This self-fertilizing mechanism benefits the plant itself and continuously enriches the surrounding soil structure over time, making it highly valuable in low-nutrient environments.
