Howdy, Sheryl...
(Guess I went off looking for that pic while you were posting!)
When I save seeds they come from a large brownish/black pod, usually with four or so seeds in them. And yep, they can be tan or darker (some are dark brown), many of them white. And you got that right, they look like large corn kernels.
The only seeds of Datura I've saved has been from D. stramonium, which is pretty much a weed here; a pretty weed but sure can take over. Those seeds are blacks and much smaller than moonvine. Maybe someone who has grown more Datura varieties than I can elaborate more.
I always like to ask folks, just to keep thing clear, "are you referring to MoonVine or MoonFlower" because so many folks interchange the two. Moonvine seems to more often refer to Ipomea alba while Moonflower refers to Datura.
Maybe I can take some pics tonight of my moonvine seeds and post. That should help you decide, eh?
