Philodendron grandipes is a unique and increasingly sought-after Philodendron species, known for its large, elongated leaves and somewhat vining growth habit. This Philodendron features lance-shaped leaves that can grow quite long, often reaching over a foot in length, and they typically have a deep green colour with a glossy sheen. The petioles (leaf stalks) are also quite long and tend to grow upright, giving the plant an elegant and somewhat architectural appearance. It belongs to the Araceae family.
The genus name Philodendron comes from the Greek words philo (love) and dendron (tree), reflecting the plant's tendency to climb trees in its natural habitat. Grandipes translates to "large foot," likely referring to the plant's large petioles.
Light: Philodendron grandipes thrives in bright, indirect light. Direct sunlight can scorch the leaves, while insufficient light may result in smaller leaves and slower growth. A spot near a window with filtered light, or a room with ample ambient light, is ideal.
Water: Allow the top inch or two of soil to dry out slightly between waterings. Water thoroughly when you do water, ensuring any excess drains away. Overwatering can lead to root rot, while allowing the plant to dry out too much can cause the leaves to wilt and brown.
Potting mix: A well-draining potting mix is essential. A standard houseplant potting mix, amended with perlite or orchid bark to improve drainage, is a good choice. Avoid mixes that retain too much moisture.
Fertilising: Feed your Philodendron grandipes with a diluted balanced liquid fertiliser every 4-6 weeks during the growing season (spring and summer). Reduce or stop fertilising during the autumn and winter months.
Temperature: Philodendron grandipes prefers typical room temperatures, roughly between 18-24°C. It is not frost-tolerant and should be protected from cold temperatures. Avoid placing it near draughts or heating/cooling vents.
Humidity: While Philodendron grandipes can tolerate average household humidity, it appreciates slightly higher levels. Using a humidifier or placing the plant on a pebble tray filled with water can be beneficial, especially in drier environments.
Growth Habit: Philodendron grandipes has a somewhat vining growth habit, meaning it will benefit from a support such as a moss pole or trellis to climb on. This will encourage larger leaves and a more upright growth pattern.
Toxicity: Like other Philodendrons, grandipes is toxic if ingested, so it's best to keep it away from pets and small children.
