Philodendron hastatum, commonly known as the Silver Sword Philodendron, is a striking tropical climber prized for its metallic, silvery-blue foliage and sleek, arrowhead-shaped leaves. A member of the Araceae family and native to the rainforests of Brazil, this variety is one of the most distinctive Philodendrons, bringing a cool, contemporary aesthetic to indoor collections.
The elongated, lance-shaped leaves have a subtle sheen that shifts between blue-grey and silvery-green depending on the light, resembling brushed metal. As the plant matures, the leaves become larger, more elongated, and deeply lobed, creating a dramatic, sculptural appearance. Philodendron hastatum climbs naturally using aerial roots, thriving when supported by a moss pole or trellis.
Elegant, resilient, and visually unique, the Silver Sword Philodendron is the perfect statement plant for collectors and designers seeking sophistication and a modern tropical edge.
Philodendron hastatum – Care Guide
Light
Thrives in bright, indirect light, which enhances its silvery tone and steady growth. Avoid harsh direct sunlight, which can scorch the delicate leaves, and deep shade, which may cause elongated, pale growth. East- or north-facing windows are ideal.
Watering
Keep the soil evenly moist but not soggy. Water when the top 2–3 cm of soil feels dry to the touch, allowing excess to drain freely. Overwatering can lead to root rot, while underwatering may cause drooping or curling leaves. Reduce watering slightly in winter.
Temperature and Humidity
Temperature: Prefers warmth between 18–28 °C; avoid cold drafts or temperatures below 15 °C.
Humidity: Moderate to high humidity (60–80%) helps maintain lush, glossy leaves. Mist regularly, use a humidifier, or group with other tropical plants to raise ambient moisture.
Soil and Potting
Use a rich, airy, well-draining aroid mix — compost combined with perlite, orchid bark, and coco coir works perfectly. This allows roots to breathe while retaining gentle moisture. Repot every 1–2 years in spring to refresh the soil and accommodate growth.
Feeding
Feed every 4–6 weeks during spring and summer with a diluted, balanced liquid fertiliser. Avoid over-fertilising, as excessive salts can dull the silver sheen or damage roots. Suspend feeding in autumn and winter when growth slows.
Pruning and Maintenance
Trim back leggy vines to maintain compact growth and encourage new shoots. Wipe the leaves regularly with a damp cloth to remove dust and highlight their metallic texture. Rotate the plant occasionally for even light exposure. Provide a moss pole or trellis to support climbing and promote larger, mature foliage.
Growth and Maturity
A moderately fast-growing climber, Philodendron hastatum can reach 1.5–2 metres indoors when supported. Juvenile plants have smaller, solid leaves, while mature specimens develop elongated, lobed foliage with a stunning silvery sheen. With consistent care, it becomes a dramatic vertical feature in any plant display.
Common Issues
-
Yellow leaves: Overwatering or poor drainage.
-
Brown edges: Low humidity or inconsistent watering.
-
Leggy growth: Insufficient light.
-
Pests: Occasionally affected by thrips or spider mites — treat with neem oil or insecticidal soap.
Background and Benefits
Native to the tropical rainforests of Brazil, Philodendron hastatum grows as an epiphyte, climbing trees in humid, shaded environments. Its metallic foliage reflects light, helping it adapt to its understory habitat. This rare species is admired for both its beauty and its resilience, making it a favourite among collectors of unusual Philodendrons.
Like other members of the genus, it’s also an excellent air purifier, filtering indoor toxins such as formaldehyde and benzene. Symbolically, Philodendrons represent abundance, growth, and strength — fitting traits for the hardy yet elegant Silver Sword.
