Peace Lilies (Spathiphyllum) thrive in low to medium indirect light, making them ideal for shaded indoor spaces. Direct sunlight can scorch their leaves, so filtered light is preferred. In contrast, Anthuriums (Anthurium andraeanum) require bright, indirect light to bloom consistently. While they can tolerate lower light, insufficient light reduces flowering and may cause leggy growth. Both plants benefit from east or north-facing windows, but Anthuriums may need supplemental light in darker environments.
Peace Lilies are more forgiving with watering but prefer consistently moist soil. They droop noticeably when thirsty, signaling the need for water. Overwatering can lead to root rot, so well-draining soil is essential. Anthuriums, however, prefer a slightly drier environment. They require watering only when the top inch of soil feels dry. Both plants dislike soggy conditions, but Anthuriums are more susceptible to root rot if overwatered.
Both plants enjoy high humidity, but Anthuriums are more demanding. Native to tropical rainforests, Anthuriums thrive in humidity levels above 60%, benefiting from regular misting or a humidifier. Peace Lilies can adapt to average household humidity but perform best with occasional misting or a pebble tray. Browning leaf tips on either plant often indicate low humidity.
Peace Lilies prefer a rich, peat-based potting mix with good drainage. A standard houseplant soil amended with perlite works well. Anthuriums, being epiphytic, need an airy, chunky mix resembling orchid bark. A blend of peat, perlite, and pine bark ensures proper aeration and mimics their natural habitat. Both plants benefit from repotting every 1–2 years to refresh the soil.
Peace Lilies and Anthuriums favor warm temperatures between 65–80°F (18–27°C). Peace Lilies can tolerate brief drops to 50°F (10°C) but may suffer leaf damage. Anthuriums are more sensitive to cold and drafts, with temperatures below 60°F (15°C) potentially stunting growth or causing leaf yellowing. Both should be kept away from air vents or cold windows in winter.
Peace Lilies require balanced, water-soluble fertilizer diluted to half strength every 6–8 weeks during the growing season. Over-fertilization can cause brown leaf tips. Anthuriums need a phosphorus-rich fertilizer (e.g., 10-30-20) every 6 weeks to support blooming. Both plants benefit from reduced feeding in winter when growth slows.
Peace Lilies produce white, spoon-shaped spathes that turn green as they age. Deadheading spent blooms encourages new flowers. Anthuriums showcase vibrant, waxy spathes in red, pink, or white, with blooms lasting weeks. Regular pruning of yellow leaves and spent flowers maintains aesthetics. Both plants may stop flowering if stressed by poor light or improper care.
Both plants contain calcium oxalate crystals, making them toxic to pets and humans if ingested. Peace Lilies may cause more severe irritation due to higher crystal concentrations. Keep them out of reach of curious pets or children.
Peace Lilies often face issues like yellow leaves (overwatering) or brown tips (low humidity/over-fertilization). Anthuriums are prone to root rot, fungal infections, and pest infestations (e.g., aphids, spider mites). Regular inspection and prompt treatment with neem oil or insecticidal soap help mitigate problems.
