FAQ

Are nasturtium flowers and leaves edible?
Yes, flowers, leaves and buds are all edible, with a peppery flavour similar to watercress. Use them raw in salads; the buds can be pickled as a substitute for capers.
Why grow nasturtium in the vegetable garden?
It is an excellent companion plant: it attracts aphids away from crops like tomatoes and beans, acting as a 'trap plant', and draws in pollinating insects.
