Vibrant, edible, butterfly-like nasturtium blooms have pleased garden enthusiasts and cooks alike for centuries. At various times in their history, they’ve been thought about a vegetable, an herb, a flower, and even a fruit! The name nasturtium originates from the latin words for nose (nas), and tortum (twist), referring to a persons’ response upon tasting the spicy, bittersweet leaves. Renaissance botanists named it after watercress, (nasturtium officinale in latin) which tastes similar.

The garden nasturtiums we grow today descend mainly from 2 species native to peru. The first, gave europe by spanish conquistadors in the late 15th to early 16th century, was tropaeolum minus, a semi-trailing vine bearing spurred, gently aromatic orange-yellow flowers with dark red areas on the petals and shield-shaped leaves. According to jesuit missionaries, the incas utilized nasturtiums as a salad vegetable and as a medicinal herb. In the late 17th century, a dutch botanist presented the taller, more energetic tropaeolum majus, a trailing vine with darker orange flowers and more rounded leaves. Given that spanish and dutch herbalists shared seeds with their counterparts, the pretty, fragrant and easy-to-grow plants quickly became prevalent throughout around europe and britain.

Nasturtiums were typically known in europe as indian cress or a translation of “capucine cress”, in reference to the flower shape, which looks like capucine monks’ hooded robes. Leaves of both species were consumed in salads; unripe seeds and flower buds were marinaded and acted as an alternative to capers. (we understand now that these pickled flower buds are high in oxalic acid and therefore must not be consumed in big quantities.).

Thomas jefferson planted them in his vegetable garden at monticello from a minimum of 1774 onward. Interestingly, in one entry in his garden book, he categorized it as a fruit amongst others such as the tomato, indicating that he ate the pickled seeds. Most nasturtiums grown at this time were the high, routing orange variety.over the course of the 19th century, breeders produced smaller, more compact types that mounded nicely into containers or formed a colorful, less sprawling edge to flower beds. Cultivars with cream and green variegated foliage appeared, in addition to the vermilion-flowered empress of india, with its strikingly contrasting blue-green leaves. These advancements paralleled the gradual shift in the understanding of nasturtiums from edible and herbal garden pillars to seeing them as decorative landscape plants. Monet let large swaths babble along a walk at giverny. The flowers and long-lasting leaves were popular in victorian arrangements and table plans. Nasturtiums were still consumed, however, and were known to help prevent scurvy, considering that the leaves are abundant in vitamin c.

Later on 20th century contributions to nasturtium breeding include the intro of varieties with spurless, upward-facing blossoms and flowers that drift greater above the leaves, ideal for bed linen or containers. A full spectrum of flower colors is now readily available, consisting of single colors– helpful for landscape designs: pale yellow, golden, orange, brick-red, cherry pink, salmon, crimson, and dark mahogany.
