A Climbing Amazonian Aroid
Philodendron billietiae is a climbing evergreen aroid grown for its long, spear-shaped leaves and bright orange-yellow stalks. It is a relatively undemanding houseplant once its basic climbing and moisture needs are met.

Native to Northern South America
This species comes from the wet tropical forests of the Guianas and northern Brazil, in Pará, where it grows as a climber through the canopy. It was first described by Croat and published in 1995.

Bright Shade, Even Moisture
Grow this philodendron in an open, well-drained yet moisture-retentive mix, such as one built from lava rock or pumice, fine fir bark, and leafmould or chopped sphagnum, set in bright but diffused light. Let the surface dry slightly before watering thoroughly in the growing season, water less in winter as growth slows, and feed monthly with a liquid houseplant fertiliser from April to September, stopping over winter.

Stem and Leaf Cuttings
New plants are raised from stem-tip cuttings or leaf bud cuttings.

Long Leaves, Orange Stalks
Mature plants produce leathery, glossy, dark green leaves with wavy, ridged edges that can reach up to 90 centimetres long, each hanging vertically from a distinctive orange-yellow leaf stalk. Given the right conditions, mature specimens may occasionally flower, showing an orange-green spathe wrapped around a cream spadix.

Watch for Scale and Mites
Keep an eye out for scale insects, glasshouse red spider mite, and mealybugs, which are the pests most likely to trouble this plant. It is otherwise generally free of disease.

Repot Every Few Years
This philodendron needs no routine pruning. Repot roughly every two to three years to refresh the growing medium and give the roots room.
