About Philodendron 'White Knight'
Philodendron 'White Knight' is a climbing cultivar grown for its bold variegation. The glossy, heart-shaped (cordate to ovate) leaves show sectorial patterns of pure white, cream, and deep green, with 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 deep purple-burgundy variegated with white stripes. It has a climbing habit and produces aerial roots at the nodes to scale supports.
Native range
A cultivated hybrid of uncertain horticultural parentage, likely derived from Philodendron erubescens crossings.

Before you buy
- The plain species (often sold as 'Red Emerald') is inexpensive and widely available; be cautious of collector-level pricing
- 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
Philodendron 'White Knight' care
- Substrate
- Chunky, well-draining aroid mix: 40% orchid bark, 30% potting compost, 20% perlite, 10% sphagnum moss.
- Watering
- Allow the top few centimetres of substrate to dry between waterings. Reduce slightly in winter.
- Humidity
- 50-70%. Tolerates average household humidity better than most variegated Philodendron cultivars, making the plain species a forgiving climber.
- Feeding
- Balanced liquid fertiliser at half strength every 3-4 weeks during the growing season.
- Repotting
- Annually while young and fast-growing; every 2 years once established, or when roots fill the pot.
Common problems
Leggy growth with small leaves
Cause: Insufficient light or no support to climb
Fix: Provide a moss pole or trellis and move to brighter indirect light; leaf size increases noticeably once the plant is climbing
Root rot
Cause: Overwatering or poorly-draining substrate
Fix: Unpot, trim affected roots, and repot into fresh chunky substrate; reduce watering frequency
Bacterial leaf spot
Cause: Overhead watering and poor air circulation
Fix: Water at the base, avoid wetting foliage, and improve airflow around the plant

How to propagate Philodendron 'White Knight'
- Methods
- Stem cutting, Node cutting. Step-by-step guide
- Difficulty
- Easy. Forgiving of missed waterings, average home humidity, and imperfect light. A solid pick for beginners or low-fuss collections.
- Time to establish
- 6-10 weeks
- True from cuttings
- Yes. Cuttings keep the cultivar's character.
- Notes
- 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.
