I think they've got minds of their own. Some of my cuttings and seedlings have done that while others don't.
I've heard you can dehydrate them until they get a little soft and then tie them to a brace like a dowel to try and straighten them out but I guess it doesn't matter to me how they look as long as they're healthy.
Maybe someone has had success other ways.
You can also try rotating the pot so it curves away from most of the sun hours too? Worked for a couple of my seedlings, but a couple now are even more twisted looking :)

Well I guess then it must happen sometimes. I have it turned away from the angle of the sun so I suppose it may take awhile but that should work. You are right about it being healthy. Its very strong. It hasn't bloomed yet I rooted it last year. Its a mystery gift that I will have to keep waiting for. I guess that's part of why we love these plants so much. Its a labor of love to wait so long.
