Josephine, I haven't seen any seeds either. I've also encountered problems with A. texana, which needs other nearby plants of that species in order to produce seed pods. Not a big problem right now, because I have enough of those. But one single A. texana plant literally can't pollinate itself and essentially I only have one Funastrum cynanchoides plant...it's spreading, but still the same plant. So that could be the problem with this one. And let's face it, there aren't as many pollinaters as there used to be. Maybe all it needs is to use a little brush to get the pollen from one bloom to another...I've done that a little bit in the past.
