Sandy, I've had a lot of problems with leaf curl lately myself. H. latifolia is the worst, the new leaves are heavily distorted and for a while the new leaves yellowed and dropped off when they were quite small. I thought it might be some sort of salt buildup in the soil, and I sat it under a slow stream of cool water in my kitchen sink for about 3 hours to leach out the soil. Since then it has stopped dropping leaves, and the new leaves are less distorted, but still not normal. It seems to have improved a lot though, and I'm hoping the new growth point in the picture will be more normal still. I've also had H. cembra, H subcalva, and H. wallichii do what looks like the same thing. I had wondered if temperature made it worse, as the plants looked normal when I got them (they had grown in a greenhouse) but quickly started distorting in my cool house.
