History
Tropaeolum minus, the dwarf nasturtium, is a compact climbing-to-trailing annual native to the Andes of Peru and Colombia. Spanish conquistadors encountered the plant in Peru and introduced seeds to Spain in the mid-16th century. Sevillian physician Nicolás Monardes described it in his 1569 treatise on New World medicinal plants, and it soon spread across Europe as a curious ornamental and peppery salad addition.
Linnaeus named the genus Tropaeolum in 1753, from the Greek tropaion, a trophy pillar hung with armor, because the round leaves reminded him of shields and the flowers of helmets. Flowers and young leaves have a pungent watercress-like flavor and remain popular as edible garnishes. It is smaller and less vigorous than the later-introduced T. majus.
Native to Peru, introduced to European gardens in the 1500s and to American colonial gardens by 1700. Thomas Jefferson grew nasturtiums at Monticello for edible flowers. A classic children's garden plant for easy germination and edible reward.
Symbolism & meaning
What It Symbolizes
Dwarf Nasturtium wears patriotic colors borrowed from Roman victors, its petals running through red, orange, and gold in classical celebratory hues. The whole plant is an edible sunset, leaves and flowers alike at home in salads and garnishes. In its peppery flavor and scrambling habit, beauty, history, and harvest all share the same tumbling stem.
- Patriotism — red-orange-yellow Roman victory colors
- Edible sunset — entire plant edible
Where the Name Comes From
