Silver-leaved Eurasian small tree historically planted as windbreak across the North American Great Plains. Cold and drought hardy, but invasive in much of its introduced range.
Hardiness ratings
| System | Rating | Temperature range | How to read it |
|---|---|---|---|
| USDA hardiness zone | Zone 2–8 | −45.6 °C to −6.7 °C | Plant tolerates down to this zone |
| RHS hardiness rating | H7 | down to −20 °C | Plant needs at least this level of cold tolerance |
| Canadian plant hardiness zone | Zone 2–8 | −40 °C to −1 °C | Plant tolerates down to this zone |
| Australian (ANBG) zone | Zone 1–4 | −15 °C to 5 °C | Plant tolerates down to this zone |
Growing notes
- INVASIVE across much of western North America — listed as a noxious weed in many states and prohibited for new planting in some. Check before planting and consider native alternatives.
- Fixes nitrogen via Frankia bacteria (actinorhizal symbiosis) rather than the Rhizobium of legumes — a non-legume nitrogen fixer
- Where already established, useful as windbreak in extreme dryland conditions
