Colorful, edible, butterfly-like nasturtium blooms have delighted 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 comes from the latin words for nose (nas), and tortum (twist), referring to an individuals’ reaction upon tasting the spicy, bittersweet leaves. Renaissance botanists called it after watercress, (nasturtium officinale in latin) which tastes comparable.

The garden nasturtiums we grow today descend generally from 2 types belonging to peru. The very first, gave europe by spanish conquistadors in the late 15th to early 16th century, was tropaeolum minus, a semi-trailing vine bearing stimulated, gently scented 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 veggie and as a medicinal herb. In the late 17th century, a dutch botanist presented the taller, more vigorous tropaeolum majus, a tracking vine with darker orange flowers and more rounded leaves. Given that spanish and dutch herbalists shared seeds with their counterparts, the quite, fragrant and easy-to-grow plants rapidly ended up being prevalent throughout around europe and britain.

Nasturtiums were commonly 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 types were consumed in salads; unripe seeds and flower buds were pickled and served as a substitute for capers. (we understand now that these pickled flower buds are high in oxalic acid and therefore must not be eaten in big amounts.).

Their decorative worth was also appreciated: flowers were used in nosegays, and planted to embellish trellises or cascade down stone walls. They became specifically popular after being shown in the palace flowerbeds of french king louis xiv.

Although it is often reported that nasturtiums were introduced to the us by the philadelphia seedsman bernard mcmahon in 1806, they were tape-recorded here as early as 1759. Thomas jefferson planted them in his veggie garden at monticello from a minimum of 1774 onward. Interestingly, 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. A lot of nasturtiums grown at this time were the tall, routing orange variety.over the course of the 19th century, breeders produced smaller, more compact types that mounded neatly into containers or formed a vibrant, less vast edge to flower beds. Cultivars with cream and green variegated foliage appeared, along with the vermilion-flowered empress of india, with its strikingly contrasting blue-green leaves. These developments paralleled the progressive shift in the understanding of nasturtiums from edible and natural garden pillars to viewing them as ornamental landscape plants. Monet let big swaths rattle on along a walk at giverny. The flowers and long-lasting leaves were popular in victorian arrangements and table arrangements. Nasturtiums were still consumed, however, and were understood to help prevent scurvy, given that the leaves are abundant in vitamin c.

Later on 20th century contributions to nasturtium breeding consist of the introduction of ranges with spurless, upward-facing blossoms and flowers that float greater above the leaves, ideal for bedding or containers. A full spectrum of flower colors is now available, including single colors– helpful for landscape designs: pale yellow, golden, orange, brick-red, cherry pink, salmon, crimson, and dark mahogany. The recent interest in edible flowers, herbs, decorative cooking area gardens and heirloom flowers has actually helped keep a complete range of old and brand-new cultivars available for each possible use.
