Nasturniums are easy to grow and make a showy display, with flowers from red to white, and orange to yellow. Young leaves, buds and flowers are edible. Buds can be pickled in vinegar and taste like caper.
The species name "majus" comes from the Latine for "larger".
Blooming Habits:
The flower varieties include single or double, with or without spurs. The spurless varieties have flowers facing up.
Culture:
Tolerates a wide range of soils. Poorer soils produce less leaves, but more flowers
Propagation:
If possible, it is better to sow nasturniums in place. They seem to suffer when being transplanted. You can also sow them inside at 65°F (18°C). Plant 5 week old seedlings 12 inches apart (30 cm).
