Tropaeolum or Nasturtiums have about 80 different species of annual and perennial varieties. Similar to watercress. It's become a popular plant, but many don't know it's edible! The flowers and leaves make a great addition to any salad or stir-fry, plus a nice hint of color. The seeds are used in dressings and garnishes. The tuber it produces is edible too.
Nasturtiums are also used in herbal medicine for their antiseptic and expectorant qualities. Some are good for chest colds, promotion of forming of new blood cells, and respiratory and urinary tract infections.
