Now you may well stop to admire these lovely angel trumpet flowers but you're probably best to leave it there. You see Datura are known for their powerful toxins. I can remember being told of a man who tied a donkey beneath a tree datura only to find it wouldn't wake up.
This species is also known as thorn apple or concombre-zombi because of these spectacular fruits. Spectacular but lethally toxic. In fact it is widely believed rogue voodoo practitioners use a preparation of Datura to damage victims in the process known as zombification....as in zombies. yes really. There's a load of detail about this utterly horrifying practice (3 days in a coffin alive and aware but unable to move!?) and other medicinal uses of the genus here but to summarise lets admire from a distance, eh?
For those of you confused by the use of Datura and Brugmansia by books and garden centres and catalogues I understand the basic rule is Datura flowers upwards whereas Brugmansia flowers hang down. The toxity is an issue with all species so do be careful if you grow these.
