Datura is 30 to 150 cm tall, with erect, forking and purple stems. The leaves are large, 7 to 20 cm long and have irregular teeth a la oaks. The flowers are one of the most distinctive characteristics of datura. They open and close, at irregular intervals, during the evening. The native range of the plant continues to remain ambiguous. It is believed that the birds carry the seeds of the datura and spread it in their droppings. The seed lies underground for a long time and germinates whenever the soil is disturbed. 

Plant Chemicals 
Datura leaves contain the same alkaloids as Belladonn, though in smaller proportions. The mid-rib and footstalk of the leaf contain a far larger proportion of alkaloids than the blade. The alkaloid consists chiefly of hyoscyamine, associated with atropine and hyoscine (scopolamine). Malic acid is also present.
