About Philodendron Pink Princess

Philodendron erubescens 'Pink Princess' · also called Pink Princess Philodendron, PPP · tropical

The Pink Princess is a climbing aroid prized for dark leaves splashed with bubblegum-pink variegation. Its one defining care need is plenty of bright, indirect light: the pink is simply an absence of chlorophyll, so too little light makes the plant revert to all-green leaves to feed itself. Warmth and steady moisture do the rest.

Cold limit: USDA 10a-12b (outdoors only in frost-free tropical climates) · RHS H1a (must be grown under glass/indoors all year, minimum 15°C) (18-27°C)

Watch for — Root rot from overwatering: Soggy compost causes yellowing leaves and mushy, blackened roots. Always let the top 2.5cm dry out, use a chunky free-draining mix and a pot with drainage holes, and reduce watering in winter.
