Frasera Caroliniensis
''Frasera caroliniensis'', commonly known as American columbo or yellow gentian, is a herbaceous perennial of the gentian family Gentianaceae found in the deciduous forest of Southern Ontario and throughout the eastern and southeastern United States.Horn, N.

When it reaches the flowering stage, the 3 – 6 inch lanceolate leaves develop (usually in whorls of four) on a round elongated stem, and approximately 50 to 100 flowers will develop a panicle, with the fruits maturing soon after. The flowers that it produces are about 1 inch in diameter and folious (tall and "spike"-like), green to yellow with purple speckles. It is a perfect and complete flower, with fou ...
