Heat-tolerant subspecies of hairy vetch suited to Mediterranean and Australian climates. Same nitrogen-fixing benefits with better summer survival.
Hardiness ratings
| System | Rating | Temperature range | How to read it |
|---|---|---|---|
| USDA hardiness zone | Zone 5–10 | −28.9 °C to 4.4 °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 5–9 | −23 °C and warmer | Zones where it can be grown as an annual — not a frost-tolerance rating |
| Australian (ANBG) zone | Zone 1–6 | −15 °C to 15 °C | Zones where it can be grown as an annual — not a frost-tolerance rating |
As a tender annual, Woolly pod vetch doesn't overwinter — the zone range shows where the growing season supports it. See the RHS rating for its actual cold tolerance.
Growing notes
- More heat-tolerant than the parent species (V. villosa) — better suited to dry-summer climates
- Excellent winter cover crop in southern Australia and California
- Crimp-roll at flowering for in-place mulch in no-till systems
