A plant I had a couple of summers ago, was thriving leaf wise but never a flower, until I moved it to an exposed, hot, dry position and it got very floriferous. It was one of Keith Hammett's bred seedlings, which I was disappointed in when it did flower, so he was happy to have it back and I got another one and 2 more. Which are in the exposed position where the original one was, and flowered very happily last season. Could it be being dry which triggered them, and hot? I always thought they needed sun, and dry. Was amazed to see some in Nhu's photos which were in the shade, but they would be dry there. Also possibly soil which is a bit poor on nutrients?
