Nasturtium

The nasturtium (Tropaeolum) are a distinctive group of herbaceous flowering plants – they represent the one and only genus within the family Tropaeolaceae. Many nasturtiums produce colorful, showy flowers and are thus planted ornamentally in gardens. Further, a few species of nasturtiums, most notably Garden Nasturtium (T. majus) and Mashua (T. tuberosum), are cultivated for culinary use.

Soil Type

Water: Nasturtium thrives in South and Central America's moist climates, requiring consistent hydration without waterlogging. Weekly watering is ideal. When grown outdoors, consider regional rainfall patterns, as nasturtium benefits from rain followed by sunshine during its growth cycle.

Propagation: Primary propagation of nasturtium occurs via seeds, requiring sunlight, mild temperatures, and well-draining soil. Prefer poor, slightly acidic to neutral conditions. Soak seeds for 12-24 hours, plant 1/2 inch deep, keep soil moist, and expect seedlings in 7-14 days. Transplant with care.
