Does anyone grow Ibicella lutea? I noticed that the stigma of the flower closes immediately(like a flytrap) after contact with pollen, perhaps to preventing self-pollination. None of my Proboscidea does this.
PS: I have some seeds of sp. for sase. You will have to use GA3 to germinate the seeds, otherwise they are not likely to germinate( or you might have to wait for a very long time).
