Datura is a flowering plant often used in ornamental gardens for the beautiful pastel trumpet-shaped flowers it produces. Datura is the genus with between nine and twelve species under its umbrella. As part of the nightshade family, it has been part of religious and cultural rituals for thousands of years, especially in ancient Chinese medicine. The plants grow to about three feet tall all over the world in tropical and moderate climates. Datura seeds develop inside a capsule covered in spines; as it ripens, it splits open and distributes the sees onto the ground.
