I have had Skinwalker for two years. I had always wanted it because it was a Stout medalist and did well in the yearly popularity contests. However, it was registered as a dormant.
Even so, I had noticed it was available in the warmer nurseries here. So I gave it a try. It has done very well: there was no die back in winter and it acts like an evergreen here in the subtropics. It flowers late in the second month of spring or early the third month. It is fairly resistant to rust. It is easily pollen fertile but I have never got it to set pods. It reblooms into the middle of summer. I sometimes have to stake the scapes.
I keep on forgetting to confirm if it is nocturnal.
