Datura stramonium

I saw this beautiful flower in our garden. Actually nobody planted it. Seeds should have come from somewhere.

First did not know what flower is that. But I searched the net and found that it is Datura stramonium.

According to wikipedia it is also known as jimson weed, ditch weed, stink weed, loco weed, Korean morning glory, Jamestown weed, thorn apple, angel's trumpet, devil's trumpet, devil's snare, devil's seed, mad hatter, crazy tea, malpitte, and, along with Datura metel, zombie cucumber is a common weed in the Nightshade Family.

All parts of Datura plants contain dangerous levels of poison and may be fatal if ingested by humans or animals, including livestock and pets. So, may not be good for your garden.

So, it is a dangerous plant but it can be used as a medical plant also. There was a time when stramonium, a drug obtained from the leaves and seeds of Datura stramonium, was used medicinally (Herbalgram). Because of the dangers of tropane poisoning, datura is not used medicinally today, and the Food and Drug Administration (FDA) has claimed it to be unfit for human consumption
