About Grindelia lanceolata Nutt.
Grindelia lanceolata Nutt. is a short-lived monocarpic perennial herb that grows up to 150 cm (5 feet) tall. Its leaves can reach up to 11 cm (4.4 inches) in length, and are usually hairless or bear only very few hairs. In summer, the plant produces yellow flower heads: these most often grow in flat-topped clusters, though occasionally a single flower head forms per stalk. Each flower head holds 12 to 36 ray flowers, which surround many disc flowers.
This species is native to the south-central United States, growing primarily in the Ozarks, the Interior Low Plateaus, and the southern Great Plains (including Texas, Oklahoma, New Mexico, and Colorado), as well as in northeastern Mexico. Isolated populations, some of which are thought to be naturalized, also occur in New Mexico, Colorado, Wisconsin, Ohio, Virginia, South Carolina, and Connecticut. Grindelia lanceolata prefers to grow in limestone glades and rocky prairies.
