I have recently discovered that the alien looking bulbs on my vines are actually seed pods. I cut one open out of curiosity and discovered that there was one brown seed, like the ones that come in the packages you buy. The rest were white. I left the seeds sitting outside on a window ledge, some remained white some turned black. I removed most of these pods from my vines which have died and am keeping them in baggies inside, I have not cut anymore open. When is it ok to remove the seeds and are the white ones viable????
