My datura are very happy right now. They are blooming like crazy. There are many names for this beautiful plant, Angel's trumpet, Datura stramonium, known by the common names jimson weed, devil's trumpet, devil's weed,thorn apple, tolguacha, Jamestown weed, stinkweed,locoweed, pricklyburr, devil's cucumber, hell's bells, moonflower  and, in South Africa, malpitte and mad seeds, is a common weed in the Solanaceae (nightshade) family.
The plants smell like tobacco and produce a lovely flower. All parts of the plants are poisonous and have been known to cause death in extreme cases of overuse. Lovely to look at though. I hope they volunteer again next year.
