Advertisement Do these plants need Xpollination to produce seeds, some of them?, all of them? I can't find much info about it. I ordered 5 Edithcolea grandis seeds and they all crumbled. I ordered another 5 seeds. I happened to notice when I passed them in front of a light while still in the small ziplock that 4 of the seeds were very transparent, appeared to be four empty seed coats. Just one obviously had a plant ready to go inside. So I want to try and produce my own seeds from my plants. I've seen the same thing with one of my fav native field plants, white rosin weed, about 7 out of 8 seeds are empty, only a seed coat.
