Cephalotus grow well in a partial to full sun position where it will receive roughly 4 or more hours of direct morning sunlight followed by light shade for the remainder of the day.
These plants prefer to be constantly damp but not soggy soil. They require the same quality of water as other carnivorous plants, so rainwater and RO water is best. You can stand the container in a shallow tray of water, allowing the tray to dry out for a day or so and then topping up to a couple centimeters.
A period of winter dormancy is vital to this plants long term health. Growth will slow during this period of time and it is important that if you are growing your plant indoors, that you keep it away from any heat sources so it can experience the cooler temperatures. It can tolerate light frosts but should be kept from being exposed to temperatures below 2deg C.
