Grindelia

Grindelia is a genus of perennial and annual plants in the sunflower family, Asteraceae. Commonly known as gumweed or rosinweed, these plants are native to the Americas, with species found throughout North and South America. Grindelia species are characterized by their sticky, resinous flower buds, which often give the plant a glossy appearance. The leaves are typically toothed and can be smooth or hairy. The flowers are bright yellow, resembling small sunflowers, and are usually borne singly at the ends of branches.

These plants are often found in dry, open habitats such as prairies, fields, and roadsides. They are known for their resilience and ability to thrive in poor soil conditions. Historically, Grindelia species have been used in traditional medicine by various indigenous cultures for a range of ailments, including respiratory issues and skin irritations. The resinous sap was sometimes applied topically. While some medicinal uses persist, it is important to note that scientific evidence supporting these claims varies. Grindelia is generally considered a hardy and adaptable plant, often playing a role in its native ecosystems.
