Where does nasturtium grow?

Nasturtium is basically a plant native to the Andes in South America in warm countries in this region (from Bolivia to Colombia). Nasturtium grows today in many other parts of the world than South America such as Europe, North America, Asia. It is a climbing plant. The nasturtium is an annual plant, that is, it dies every year.

When to harvest nasturtium?

In general, in Latin America we can collect nasturtium flowers and leaves all year round (tropical or subtropical climate), but you must wait for the plant to have a considerable amount of leaves and flowers. In other parts of the world, such as Europe, the plant must be harvested in spring or summer. Nasturtium flowering occurs in Europe generally from June to October.

Interesting Observations

– Due to the high number of plants to treat cough (read: natural cough remedy ) this is perhaps not the most effective medicinal plant for this indication (Create health prefers: thyme , garlic , etc.), but they have proven to be a good complement and also helps treat and prevent colds through its antibiotic effect and its leaves rich in vitamin C.

– In spring and summer, do not hesitate to plant nasturtium in the garden or on your balcony and put some nasturtium in your salad, because the leaves are rich in vitamin C and are therefore very interesting nutritionally.

– The term  Tropaeolum , created by the botanist Carl Linnaeus, comes from the ancient Greek  tropaion , referring to nasturtium leaves and flowers, similar to a trophy on a battlefield.

– The introduction of nasturtium in Europe, coming from South America, took place in 1684.

– Put some nasturtium leaves (rich in vitamin C) and nasturtium flowers in your salad. The taste resembles that of watercress, which is why this plant is often called “Peru watercress”.
Prefer the young leaves for a salad.

– This is one of the few medicinal plants that you should avoid drying, as it loses effectiveness.
