From our seed source, Frank Morton of Wild Garden Seeds: "A low-growing, big-flowering, eye-catching native species suitable for pathway borders. Also known as Hopi tea or Greenthread, Navajo Tea is an important medicinal plant in the southwestern US. The entire plant, filiform leaves and yellow petals, can be used as a yellow dye source and an herbal tea that alleviates aches and pain. Luteolin, one of the flavonoids found in Navajo Tea, is notable for its anti-inflammatory effects."
Also called "Hopi Tea", or "Stiff Greenthread", for its delicate leaves, the plant is considered an annual or short-lived perennial. It's a real beauty. Enjoy!
