Goldthreads

Threeleaf goldthread is a forest plant that gets its common name from the three leaves which top each of its branches, plus its yellow, threadlike roots. It usually has a singular, white flower at the end of its long stem.

The long and narrow rhizomes crawl sideways and breed with toothpicks in the basement. The root leaves are bird-legged double leaves, 5 small leaves, fallen egg shape, glossy and slightly thick. The leaflet splits in three, the base is wedge-shaped, there is almost no petiole, and there are sharp saw blades at the edges. Bring out a brownish flower stalk that is 4 to 15 cm high and place one flower facing upward. The diameter of the flower is 1.2 to 1.8 cm, and the white petals look like 5 pieces of sepals and are oval. The petals secrete nectar and are yellow and smaller than the sepals. The fruit is opened like a squirrel in a boat-like bag, the length of the bag is 6 to 9 mm, and the length of the bag is 5 to 6 mm.

The low-growing idaho goldthread species are perennials with divided evergreen foliage and white to greenish yellow-hued flowers. Some species are listed as endangered in their native regions.

Their Latin name Coptis is derived from the Greek kopto, which means "to cut," a reference to their dissected leaves.
