Hi, has anyone had any success with growing Bougainvillea

from seed? If you have, how did you go about it?

I live in the U.K., and at the moment several pods are still on my plant, although the bracts have gone really dry, and faded looking. The pods look as if they have swollen somewhat, so l am hopeful that there may be seed/seeds inside. I don't know how long it takes for the seeds to ripen sufficiently to be gathered, or how to tell when is the right time to do so. Also, if there are any, would they have to be stored in a particular way before planting, and when would they have to be planted?

Also, what are baggies that l keep reading about on here?
