I bought this pot of Datura metel recently at Kovan. Isn't it beautiful? I first saw it in Chiang Mai in January 09 when I went on a plant sourcing trip with a colleague.
This double-petaled variety which I bought from Kovan apparently has leaves that are slightly different from the one I grew from seeds from the Thailand batch of plants.
The exciting thing is I understand there is a white double-petaled variety too. I will definitely keep a lookout for it in our nurseries!
