One of the many varieties of annual Nasturtium grown for their bright colours, edible leaves, flowers and seeds (which can be pickled). Prone to blackfly, which can be kept at bay by a mild spray with a 1-10 detergent solution.
Thrives from June until frosts, in poor soil, full sun and partial shade.
Propagate by seed under glass in February, or in April where they are to flower. Will self-sow in mild areas.
