Sisymbrium Columnae Var. Leiocarpum

Cocklebur, scientifically known as Sisymbrium columnae var. leiocarpum, is a unique and often misunderstood plant native to certain regions of the United States. This variant of the cocklebur species is distinguished by its compact, spiny fruit capsules that resemble small, rounded burrs. While it may appear invasive in some areas, it plays a vital role in supporting local ecosystems by providing food and shelter for various wildlife species. Its presence in agricultural fields has also sparked debates over its impact on crop production. Despite its prickly appearance, the cocklebur is a fascinating subject for botanical study and ecological research.
