Philodendron comes from the Greek words philo- or "love" and dendron or "tree". This refers to the epiphytic nature of many Philodendron and their adaptations to growing on or up trees.
Billietiae was named after the discoverer of this species Dr Croat's friend Frieda Billiet.
P. billietiae has large, waxy leaves with orange petioles. A quality of philodendrons is that they do not have a single type of leaf on the same plant. Instead, they have juvenile leaves and adult leaves, which can be drastically different from one another. As the P. billietiae matures the leaves becomes larger and with more defined lobes.
P. billietiae wants bright, indirect light. It can tolerate some direct light but avoid hot midday sun or the leaves will scorch.
Yellowing leaves are a sign of too much water. Ensure the pot has good drainage and allow the surface of the soil to dry between watering. Older leaves will naturally yellow and die eventually.
If the soil is staying moist for more than two weeks between watering, or the soil feels soggy or very wet after a week then consider repotting the plant into a smaller container: the roots staying wet for too long will lead to root rot and a quick decline in the plant's health. When repotting use a well drained mix (see aroid soil)
P. billietiae can take some direct sun without damage but requires acclimatisation first or leaves will become bleached, will turn brown and eventually die. When moving your plant into an area which gets direct sunlight build up the plant's tolerance first. Limit the amount of direct sun to an hour a day for a few days, then two hours, then three and continue to slowly increase the plant's light exposure until it is fully acclimated.
When moving the plant outdoors, choose a spot in shade or that gets dappled or screened sunlight. Let the plant slowly acclimate to being outdoors and never move the plant into direct sun without slowly building up a tolerance first. Some direct morning or evening sun is fine but hot midday light will scorch the leaves.
