Nasturtium
Tropaeolum majus
A trailing annual. Leaves and flowers taste like watercress-wasabi. Immature seeds pickle as a caper-like condiment. Not true watercress (Nasturtium officinale — same common-name trap, different plant historically confusing).

From the existing encyclopedia
Nasturtium is a dried botanical traded as cut leaf, flower, seed, or root for tea and seasoning. Buy food-grade quality from suppliers who publish lot and origin; avoid mystery bulk without COA for sensitive items. Balances with honey or dates in warm drinks when used as food sweetening. When substituting dried Nasturtium for fresh, use about one-third the volume and bloom in fat or hot water before adding acid or dairy.
Edible portions
- leaves
- flowers
- green seeds
Absence of a portion from this list means it is not treated as food here — not that every other part is toxic.
Growing
- Climate. Annual, frost-tender
- Light. Full sun for flowers; too-rich soil = leaves, few blooms
- Soil. Lean to average, well-drained
- Planting. Direct-sow large seeds after frost.
- Harvest. Pick flowers daily; leaves anytime; green seeds before they harden.
Preparation and culinary uses
- Salad garnish
- Pickled green seeds
Nutrition and compounds
- Vitamins (qualitative, well-known associations). vitamin C — not milligram values.
AAA interpretation Food first. These associations explain why a plant shows up in a nutrient conversation — they are not a supplement shopping list.

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.
