Is anyone growing Proboscidea or Ibicella, or know where I might come by some seed? I would like to try again this season to grow these plants, and welcome any cultural advice as to how to best germinate the seed (I have had no luck with this) and how best to grow the plants. I grew Ibicella once, and had no problem germinating the seeds, but that was before I heard how difficult they were to germinate. Since then, not a single seed has germinated for me.
