About
Philodendron 'White Knight' is an exceptionally striking climbing cultivar highly coveted for its bold variegation. The glossy, heart-shaped (cordate to ovate) leaves showcase dramatic sectorial patterns of pure white, cream, and deep green, with high-contrast half-moon variations frequently appearing on healthy leaves. A key feature distinguishing 'White Knight' from similar cultivars like 'White Wizard' is its stems and petioles, which are a deep purple-burgundy variegated with white stripes. It has a climbing habit and produces aerial roots at the nodes to scale supports.

Before You Buy
Shared checklist for Philodendron erubescens and its cultivated forms
- The plain species (often sold as 'Red Emerald') is inexpensive and widely available — be cautious of pricing implying rarity
- For 'Pink Princess' or 'White Princess', check the variegation percentage in photos — heavily white/pink sectored cuttings are harder to establish and more valuable, but also more fragile
- Look for firm stems and healthy nodes; a cutting with a mushy or blackened base is unlikely to root
- All Philodendron are toxic if ingested — keep away from pets and children
Propagation Guide

Shared across every form of Philodendron erubescens — see this form's own Morphology for variegation-specific propagation notes.
6-10 weeks
Cultivar character is preserved through vegetative cuttings
Roots readily from stem or node cuttings in water or moist substrate. The plain species propagates fast and true; variegated sports like Pink Princess and White Princess need a cutting taken at a visibly variegated node to preserve the sectoring.
Care Guide
Growing Conditions
General care shared across all forms of Philodendron erubescens — cultivated forms may need brighter light or higher humidity than the plain species; check this form's Quick Facts above.
Chunky, well-draining aroid mix: 40% orchid bark, 30% potting compost, 20% perlite, 10% sphagnum moss.
Allow the top few centimetres of substrate to dry between waterings. Reduce slightly in winter.
50-70%. Tolerates average household humidity better than most variegated Philodendron cultivars, making the plain species a forgiving climber.
Balanced liquid fertiliser at half strength every 3-4 weeks during the growing season.
Annually while young and fast-growing; every 2 years once established, or when roots fill the pot.
Common Problems
Leggy growth with small leaves
Insufficient light or no support to climb
Provide a moss pole or trellis and move to brighter indirect light — leaf size increases noticeably once the plant is climbing
Root rot
Overwatering or poorly-draining substrate
Unpot, trim affected roots, and repot into fresh chunky substrate; reduce watering frequency
Bacterial leaf spot
Overhead watering and poor air circulation
Water at the base, avoid wetting foliage, and improve airflow around the plant
