I tried Oncocyclus here. I built a raised bed with screened granite. I
planted them in the fall when they arrived from the iris society. They
sprouted and grew the first spring. I covered them the first summer,
ensuring good air circulation, and removed the cover in late fall. They
never came up the next spring. I poked around and found them all dead.

The people in the iris society concluded they got too much winter rain
here. We average 8" / 200mm rain per annum, 60% during the summer monsoon
July-September.
