Daisy-like Flowers - Goldenrod

     

Asteraceae (Compositae) - Sunflower family
Giant Goldenrod Solidago gigantea
Terminal branches are covered on one side by 1/8" wide flowers. Single stalk (not fuzzy) with long alternating leaves, up to 7" long. Leaves have sharp wide-spaced teeth, 3 main veins. Upright plant can grow to 7 feet tall. Colonies grow from the roots. Goldenrods are not wind pollinated so do not produce hay fever. Flowers are a source for yellow dye.
