About Datura quercifolia Kunth
Datura quercifolia Kunth was first formally described by Alexander von Humboldt in 1818. This species gets its specific epithet quercifolia from its green leaves, which have a shape similar to oak leaves. Plants of this species can grow in either a prostrate or an upright bushy growth form; bushy individuals can reach a maximum height of 3 feet. It produces green seed capsules covered in long, sharp spines. Like the seed capsules of some other Datura species, these split open through four equal valves. Its flowers are funnel-shaped, white with pale violet coloring, tipped with five short triangular teeth, and measure less than 2 inches in length.
All parts of Datura plants, including this species, contain dangerous levels of poison. Ingestion by humans or animals, including livestock and pets, can be fatal. Buying, selling, or cultivating Datura plants is prohibited in some regions.
