Neomarica gracilis? Here is a link that might be useful: Walking Iris

Thanks! I think it is indeed Pachira aquatica which apparently loves moisture so they can't have been overwatered? They're not in styrofoam cups but 10 inch tall white pots but with no drainage which I suspect is the problem. I will repot as suggested. Thanks again for your help.

It's a variegated peperomia, and yes, it is flowering. The flowers consist of about what you see there...nothing showy. The fact that it is flowering means you're taking great care of it. Congratulations. bob

Did you save seeds? I would really like to grow it here in southeastern Germany and Austria. We might change seeds then, since Iôve breeded some very interesting Cucurbita varieties for British climate too. If youôd like, please write to: ludwig.ammer@gmail.com
