IntermediatePhilodendron billietiae

About
Philodendron billietiae Croat is a hemi-epiphytic aroid native to lowland rainforest in Brazil, Guyana and French Guiana. It was found by Frieda Billiet in French Guiana in 1981, living material was grown in the greenhouses of the National Botanic Garden of Belgium at Meise, and it was described as a new species in 1995; the epithet honours its discoverer. Its most distinctive features are the orange-yellow petioles and the long, narrow leaves with wavy edges, which set it apart at a glance from philodendrons with green leaf stalks. As a climber it develops larger leaves when trained up a moss pole or similar support. General care follows the genus: bright light without direct sun, fairly high humidity and warmth. It dislikes cold and waterlogging, so in Japan it must be kept in a warm room in winter. Species-specific data on growing temperatures or adult size are scarce. In Japan it is sold as a collector's aroid by specialist nurseries and online shops, from tissue-culture plantlets to large plants.
