any plant of the genus Tropaeolum, cultivated for its showy, usually orange, red, or yellow flowers or for its fruit, which is pickled and used like capers.
Origin: 1560–70; < Latin nāsturtium, nāsturcium a kind of cress, taken to mean, perhaps by folk etymology, something that wrings the nose (referring to its acrid smell). See nose, tort, -ium
any of various plants of the genus Tropaeolum, esp T. major, having round leaves and yellow, red, or orange trumpet-shaped spurred flowers: family Tropaeolaceae
[C17: from Latin: kind of cress, from nāsus nose + tortus twisted, from torquēre to twist, distort; so called because the pungent smell causes one to wrinkle one's nose]
c.1150, "plant like watercress," from L. nasturtium "cress;" the popular etymology explanation of the name (Pliny) is that it is from L. *nasitortium, lit. "nose-twist," from nasus "nose" + pp. of torquere "to twist" (see thwart); the plant so called for its pungent odor.
