There are many, many kinds of datura out there. I would have to say that it is very possible that this is a datura, but what kind would have to be determined after the bloom opens. When it does open, you can post a picture on the brug and dat forum and there is an expert that visits that forum a lot and he will help with ID.
I received these seeds in a trade and they swear that they are triple yellow datura's. The leaves looks like a datura but the little tiny buds is what is confusing me???? I can't wait to see what pops out of this one. I am going to be so dissapointed if I don't get a triple yellow this season. I planted all the different datura's seeds I received and I would hope that the person that traded this with me would not pull such a durty trick.
Kit, I am not a brug expert (never grown one, only annual datura) but I do know that if the seeds came from a plant that is a hybrid, you will almost definitely get a different daughter. That is one of the excitements about planting seeds, you never know what you will get! I hope this turns out to be something good, but hybrids almost never come true from seed :(
The leaves closely resemble the vine that Gardenwife loves: bittersweet nightshade, also in the Solanacae family.
if it ease ur mind some, the triple yellow datura i had last year, came from a seed that was label single yellow datura. to my amasement, i never had a single yellow flower but doubles and triples. the very reason why i said above... no way of telling what the bloom will be till they open up for U. hang in there, u do not have too long to wait for the bloom. good luck :).
