Native plant

Compass Plant is a very tall prairie plant that produces a beautiful blooming display. Large yellow flowers, about 4 inches in diameter, occur along nearly the entire length of the central stalk, reaching heights of up to 12 feet.  Blooming occurs mid summer for about a month and a half.  Its dramatic height and abundant blooms make this a good choice for the back of garden beds or along fences or other structures.
