I am winter sowing mine. Hope it works. It is perennial, so it should be okay to winter sow it. Go to the Winter Sowing Forum for instructions on winter sowing. I just use 2-litre soda bottles, cut in half, poke drainage holes in the bottom, make a vertical slice in the bottom part of the top, so you can fit it into the bottom part. Fill the bottom part with POTTING soil, water it well until it drips from the bottom. Sow the seed, label the container, put the top on (without the lid), and put it outside.

Should be fine to start it now, Pedro. Mine is for butterfly larvae. Hope it grows. If not, I'll just get a small plant. I've heard it's a pretty vigorous vine.
