The Philodendron silver sword (Philodendron hastatum ‘Silver Sword’) is a gorgeous climbing Philodendron that is beloved for its pale, silvery green color and arrow-shaped leaves. As it matures, its leaves become increasingly elongated and tri-lobed. Paired with its climbing growth habit, this impressive foliage adds an instant tropical feel to any room. While it is native to rainforests across South America, this Philodendron has become popular as a houseplant. Before adding one to your home, pet owners and parents of young children should be aware that like all Philodendrons, the Philodendron silver sword is considered toxic to pets and humans if ingested.
This Philodendron thrives with plenty of bright, indirect light. Choose a spot directly next to a sunny window, but avoid prolonged exposure to harsh, direct sunlight if possible. At the same time, be aware that a lack of light will result in lackluster-looking leaves and leggy, stunted growth.
Soil
As an aroid, the Philodendron silver sword needs an airy soil mix that retains some moisture but drains well. You can find soil mixes designed for aroids online or at specialty plant shops, or you can easily make your own. Combine equal parts indoor potting soil, perlite, and orchid bark mix for a chunky, rich soil mix that your Philodendron silver sword will love.
It’s important to keep these plants watered well, especially during the spring and summer. The soil should stay evenly moist, but not soggy. To prevent overwatering, allow the top inch of soil to dry slightly between waterings and then water well. Always allow the excess water to drain from the pot’s drainage holes to avoid drowning the roots and causing root rot.
Native to rainforest conditions, these Philodendrons appreciate warm temperatures and medium to high humidity. Standard household temperatures are usually ideal, just ensure you don’t expose your plant to any extreme fluctuations or temperatures below 60 degrees Fahrenheit (or 15 degrees Celsius) for an extended period of time. While the Philodendron silver sword can grow in average household humidity levels too, they tend to run on the dry side for this plant. If you really want to encourage lush, healthy growth, increasing the humidity around your plant is a great way to do so. Try grouping it with other houseplants, placing it on a pebble tray filled with water, or putting it near a humidifier to provide it with humidity it will love.
