Growing notes
- INVASIVE in eastern North America — banned outright in several US states and listed as a noxious weed in many others. Do not plant where it is listed as invasive — check state and county rules.
- Fixes nitrogen via Frankia bacteria (actinorhizal symbiosis) rather than the Rhizobium of legumes — a non-legume nitrogen fixer
- Berries are edible and highly nutritious where the plant is already established — gather rather than plant
