American Thorow Wax

Bupleurum americanum, commonly known as American Thorow Wax, is a perennial herb native to the eastern United States, particularly found in open woods, meadows, and along roadsides. This plant typically grows to a height of 1 to 3 feet, exhibiting an upright form with a bushy appearance. Its leaves are alternate, lanceolate, and can reach up to 4 inches in length, providing a lush green backdrop to its distinctive yellow-green flowers that bloom in umbrella-like clusters during late spring to early summer. The fruit is a small, flattened capsule containing several seeds, which are dispersed by wind and animals, aiding in its propagation across its native range.
