Philodendron erubescens or Blushing Philodendron is a perennial evergreen vine native to Colombia. The shiny dark green leaves are up to 10 inches (15 cm) long by 7 inches (17.5 cm) wide. Leaves are shiny on top and coppery underneath on purplish petioles that are as long as the leaves themselves. Our plants have been growing here for over 30 years and have only attained a height of 12 feet (~3 to 4 m). They are of easy culture and make an excellent houseplant. NOTE: All plant parts are considered poisonous.
Blooming: In the greenhouse, the plant can bloom at any time of the year. The spathe is boat shaped and up to 6 inches (15 cm) long, with dark purple on the outside, and crimson inside, with a white spadix.
Culture: Philodendron erubescens need filtered sunlight or high interior lighting. The plants do very well under artificial light. In the greenhouse, we use a soil mix consisting of 2 parts peat moss to 1 part loam to 1 part sand or perlite. To each 0.01 cubic yard of soil mix, we add 14-14-14 Osmocote slow release fertilizer. Plants are well watered and allowed to dry slightly before watering again. Fertilizer is applied monthly during the growing season. Plants grown in containers like to become pot bound and should only be repotted when the root mass has taken over 0.75% of the room in the container. During the winter months, plants should be kept cool and water is somewhat restricted.
Propagation: Philodendron erubescens is propagated from cuttings and layers.
Philodendron erubescens was featured as Plant of the Week December 16-22, 2005.
