Cool-season cover-crop pea — smaller seed and habit than garden pea (P. sativum), grown for biomass and nitrogen fixation rather than fresh eating.
Hardiness ratings
| System | Rating | Temperature range | How to read it |
|---|---|---|---|
| USDA hardiness zone | Zone 2–9 | −45.6 °C to −1.1 °C | Zones where it can be grown as an annual — not a frost-tolerance rating |
| RHS hardiness rating | H7 | down to −20 °C | Plant needs at least this level of cold tolerance |
| Canadian plant hardiness zone | Zone 2–9 | −40 °C and warmer | Zones where it can be grown as an annual — not a frost-tolerance rating |
| Australian (ANBG) zone | Zone 1–5 | −15 °C to 10 °C | Zones where it can be grown as an annual — not a frost-tolerance rating |
As a tender annual, Field pea (Forage pea) doesn't overwinter — the zone range shows where the growing season supports it. See the RHS rating for its actual cold tolerance.
Growing notes
- Different cultivar group from garden pea — same species but selected for cover-crop and forage use
- Often sown in mix with oats or rye for combined nitrogen and carbon contribution
- Cool-season crop — sow autumn in mild climates, very early spring in cold
