One of our most extraordinary trees - a 3 in 1 - This ALDER (Alnus) grows in wetland habitats. Its got nodules on its roots that provide housing for nitrogen-fixing bacteria, and it has ectomycorrhizal fungi colonizing its root hairs to bring in needed nutrients from outside its wetland substrate. [In addition, like other plants, it also has fungal endophytes living inside it, fungi that help protect it from pathogens and predators.]
