Edible portions
- leaves and seed pods as a sour nibble
Absence of a portion from this list means it is not treated as food here — not that every other part is toxic.
Growing
- Climate. Weed annual/perennial
- Light. Sun to shade
- Soil. Anywhere
- Planting. Uninvited.
- Harvest. A pinch, not a potful.
Preparation and culinary uses

Honest incompleteness is preferred to fabricated completeness. If a section is missing, no record for it is attached here — not a claim that the plant lacks that characteristic, and not that it was omitted as a secret.
