    Vibrant, edible, butterfly-like nasturtium blooms have thrilled gardeners and cooks alike for centuries. At different times in their history, they’ve been thought about a veggie, an herb, a flower, and even a fruit! The name nasturtium comes from the latin words for nose (nas), and tortum (twist), describing a persons’ reaction upon tasting the spicy, bittersweet leaves. Renaissance botanists named it after watercress, (nasturtium officinale in latin) which tastes comparable.

    The garden nasturtiums we grow today descend mainly from 2 species belonging to peru. The first, brought to europe by spanish conquistadors in the late 15th to early 16th century, was tropaeolum minus, a semi-trailing vine bearing stimulated, lightly aromatic orange-yellow flowers with dark red spots on the petals and shield-shaped leaves. According to jesuit missionaries, the incas utilized nasturtiums as a salad veggie and as a medicinal herb. In the late 17th century, a dutch botanist presented the taller, more energetic tropaeolum majus, a tracking vine with darker orange flowers and more rounded leaves. Because spanish and dutch herbalists shared seeds with their counterparts, the quite, fragrant and easy-to-grow plants rapidly became extensive 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 resembles capucine monks’ hooded bathrobes. Leaves of both types were eaten in salads; unripe seeds and flower buds were marinaded and served as a replacement for capers. (we know now that these pickled flower buds are high in oxalic acid and therefore must not be eaten in big quantities.).

    Their ornamental worth was likewise valued: flowers were utilized in nosegays, and planted to adorn trellises or cascade down stone walls. They became specifically popular after being shown in the palace flowerbeds of french king louis xiv.

Thomas jefferson planted them in his vegetable garden at monticello from a minimum of 1774 onward. Remarkably, in one entry in his garden book, he classified it as a fruit among others such as the tomato, indicating that he consumed the pickled seeds. The majority of nasturtiums grown at this time were the tall, routing orange variety.over the course of the 19th century, breeders produced smaller sized, more compact types that mounded neatly 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 steady shift in the perception of nasturtiums from edible and natural garden essentials to seeing them as decorative landscape plants. Monet let big swaths babble along a walk at giverny. The flowers and lasting leaves were popular in victorian arrangements and table arrangements. Nasturtiums were still eaten, however, and were known to help avoid scurvy, considering that the leaves are abundant in vitamin c.

    Later 20th century contributions to nasturtium breeding consist of the intro of ranges with spurless, upward-facing blooms and flowers that float greater above the leaves, best for bed linen or containers. A complete spectrum of flower colors is now available, consisting of single colors– useful for landscape styles: pale yellow, golden, orange, brick-red, cherry pink, salmon, crimson, and dark mahogany.
