was just wondering what people do to collect seeds from Datura? Ive got a double Purple with a few pods on it and rather than having them grow allover under the mother plant I am thinking of collecting them...

I would or they come up all over neat plants but they can get carried away.

I did some reading up on collecting them..something about tying a bag over the pod...I also read removing the pod before it breaks open..Just wondering what works best..
