We wouldn’t select plants for a living wall that are poisonous or allergenic to people.
A living wall can indeed help you to achieve biodiversity net gain (BNG). Using soil, and purposefully curating a plant palette that supports local biodiversity will aid net gain. You may find the guides we created with AECOM on using green infrastructure to help achieve BNG useful. These can be downloaded here. They cover how to design living walls (and green roofs) to achieve different BNG targets.
