Nasturtium flowers and plants are edible. Some use the seeds as a substitute for capers. Nasturtiums are rich in vitamin C, but only when eaten raw. Cooking them destroys the vitamin C. Nasturtiums will give an antibiotic boost so when you feel illness coming on, eat two or three of the leaves every day.
Nasturtiums are also traditionally used for skin and hair care. Nasturtium tea stimulates hair growth by increasing the flow of nutrients to the scalp. Nasturtiums are also said to reduce acne and the tea can be applied to oily skin.
How to harvest: Take some flowers and leaves from the plant and leave some so that the plant will continue to grow. Remove gently so that the roots are not disturbed.
How to prepare: Nasturtium flowers and leaves can be picked and used as a pretty and nutritious garnish for salads, or simply eaten plain for health benefits. The seeds can be pickled in vinegar to make “capers.”
