The Philodendron ‘Grey’, also known as the Silver Sword or Grey Philodendron, is an elegant climbing aroid admired for its cool-toned, silvery-grey foliage. Its elongated, sword-shaped leaves develop a striking metallic sheen that adds modern sophistication to any plant collection. Native to Brazil, this philodendron thrives indoors and makes an excellent choice for trellises, moss poles, or decorative planters.
Size and Growth
In indoor conditions, the Philodendron ‘Grey’ can grow 3–6 feet (90–180 cm) tall with support. Its vining habit and climbing tendency make it ideal for vertical displays. As the plant matures, leaves can grow larger and develop an even stronger silvery hue.
Pet Friendliness
This plant is toxic to pets if ingested. It contains calcium oxalate crystals that can cause irritation or digestive discomfort. Keep out of reach of cats and dogs.
Care Instructions
Light: Prefers bright, indirect light. Too little light can dull its coloration, while too much direct sun may scorch leaves.
Watering: Allow the top 1–2 inches of soil to dry before watering again. Keep evenly moist but not soggy. Reduce watering in winter.
Humidity: Enjoys moderate to high humidity (50–70%). Consider misting or using a humidifier for best results.
Temperature: Maintain between 18°C–27°C. Protect from drafts and avoid temperatures below 15°C.
Soil: Use a chunky, well-draining aroid mix with orchid bark, perlite, and peat or coco coir.
Fertilizer: Feed monthly in spring and summer with a balanced liquid fertilizer diluted to half strength. Pause in fall and winter.
Repotting: Repot every 1–2 years or when root-bound. Provide a moss pole or support to encourage upright growth.
Pro tip: To keep your Philodendron ‘Grey’ vibrant and healthy, train it up a moss pole. As it climbs, it will produce larger, more dramatic leaves with enhanced silver tones.
