Please!!!!!!!!!!!
Someone answer....

Apparently propagation from seed is rather rare. A few years back some there was some discussions on these forums. If you Google for ~propagation "bougainvillea seed" site:gardenweb.com the top hit a few minutes ago was about seed and the other hits are mostly about other methods of propagation. Follow the seed link carefully, it meanders a bit until about two thirds the way down the page it gets to some success stories, pictures of seed pods etc.

I know of one case where a frozen bougainvillea was successfully regenerated from a root cutting. I don't know if I ever reported this here.

Thanks!!!
So it is easier to propagate them from cuttings?
How?

There is a lot of material on rooting cuttings here: Rooting Bougainvillea Cuttings

Recurrent suggestions are semi-hardwood, rooting compounds, potting medium and keep moist.

Thanks!!!
