Two years and 8 months ago I planted 10 mixed epiphyllum seeds that I bought from Thompson and Morgan. Eight of them germinated and lived. The seed catalogue said that although these cacti usually take 4+ years to flower, these ones would flower in 2 years and 6 months. I have attached pictures of four of them (I hope). A 2' metal ruler hangs in each photo for scale. Some of the plants have some thin and some broad leaves (photo 2), consistent with my belief that the thin leaves broaden as they mature. But some have almost entirely broad leaves (photo 3), and some have almost entirely thin leaves (photo 4). They were all planted at the same time. Some of the leaves thin out and then widen - see photo 1 for the best example of this. None of them show any signs of blooming. I now have them inside for the winter, in a decently-lit but very cool room - it won't freeze but it may come close to it. Here are my questions: 1. Any predictions of blooming? 2. Do they look normal? 3. What does the thinning and then widening imply? 4. Do the different types of leaves, in terms of thickness, have any significance? 5. I have not watered them for 2 weeks and they are absolutely bone dry. My plan was to water once a month - with no fertilizer - during the winter; does that seem adequate? 6. They insist on growing primarily on one side of the container, regardless of how they are oriented vis a vis the sun. Any explanation?
