|Nasturtium (Tropaeolum majus)|
The fresh leaves and flowers give bite to savoury foods, and the green seed pods can be pickled and used as capers. The whole plant, a reputed rejunevator and aphrodisiac, is used in hair and scalp tonics. The seeds contain an antibiotic and an infusion treats coughs, colds and infection.
The vitamin-rich flowers attract hoverflies which eat aphids and its local name is Indian Cress, grown in the Andes for 8,000 years.
