The Ceanothus shrubs & trees (Ceanothus spp.) are just past their peak. But they have offered a glorious view. In the forest it is especially important to have the early colonizing trees because, while not being in the legume family, they fix nitrogen from the air into soluble nitrogen nodules on their roots—just like beans & peas.
Other non-leguminous nitrogen fixers include: Alder trees & shrubs (Alnus spp.), bayberry & sweet gale (Myrica spp.), & sweetfern (Comptonia peregrinal).
