Anybody grow this, I believe the common name is yellow morning glory? My daughter brought home some unknown seed from Puerto Escondido,Mexico last January. It seemed moldy but I planted and have five babies. On the vines and climbers forum there was a discussion of ipomoea tuberosa and that discussion and links helped me identify this vine as a merremia aurea. Right now it is in my GH and waiting for some heat to come outside.I got some good information doing a google search.
Merremia aurea
someone very nice here in DG, shared a plant with me last year. unfortunately, the plant just grew and grew, but no flowers. it is slow grower... at least for me. i planted them next to the rest of morning glory. figuring they have the same growing habit. i was disappointed cause i never saw any flower. http://www.desert-tropicals.com/Plants/Convolvulaceae/Merremia_aurea.html , http://www.starr-nursery.com/Merremia%20aurea.htm
