The Spathiphyllum ‘Domino’, commonly known as Spath Domino or Variegated Peace Lily, is a popular houseplant cherished for its elegant appearance. This plant offers a striking aesthetic to any indoor setting, making it a favored choice among plant enthusiasts and beginners. Belonging to the Araceae family, it is a type of Peace Lily with distinctive visual qualities that set it apart.
Unique Characteristics of Spath Domino
The ‘Domino’ variety distinguishes itself from other Peace Lilies through its unique variegation. Its glossy, dark green leaves are adorned with splashes and streaks of white or cream, creating a captivating contrast resembling domino patterns. These leaves can grow quite large, contributing to its lush, tropical appearance. While valued for its foliage, the Spath Domino also produces classic Peace Lily flowers, composed of a white spathe (a modified leaf resembling a hood) and a yellow spadix. These elegant, white, calla-like blooms emerge on slender stalks, adding to the plant’s ornamental appeal.
Spath Domino Care
Light
Spath Domino thrives in bright, indirect light conditions. Placing it near a north or west-facing window is ideal, as these locations provide filtered light without harsh direct sun exposure. Direct sunlight can scorch its variegated leaves, leading to damage. Conversely, insufficient light can cause the plant to produce fewer flowers and may reduce the vibrancy of its white variegation.
Watering
Proper watering is important for the Spath Domino’s health. The plant prefers consistently moist soil, but it is important to avoid waterlogging, which can lead to root issues. Water thoroughly when the top inch or two of soil feels dry to the touch, or when the plant’s leaves begin to slightly wilt, signaling thirst. Using filtered water or allowing tap water to sit for 24 hours before use can prevent leaf tip burn caused by chlorine.
Soil
A well-draining potting mix rich in organic matter provides the best environment for Spath Domino roots. This type of soil allows for adequate aeration while retaining sufficient moisture, preventing both waterlogged conditions and rapid drying out. A standard houseplant potting mix is generally suitable.
Humidity
Originating from tropical regions, Spath Domino prefers higher humidity levels, ideally between 60-70%. In average household humidity, the plant may still adapt, but increased humidity promotes optimal growth and helps prevent brown leaf tips. Methods to boost humidity include regular misting of the foliage, placing the pot on a pebble tray filled with water, or using a room humidifier.
Temperature
Spath Domino grows best in consistent indoor temperatures ranging from 65 to 80 degrees Fahrenheit (18 to 27 degrees Celsius). While it can tolerate slightly cooler temperatures down to 60 degrees Fahrenheit (15 degrees Celsius), growth may slow below 70 degrees Fahrenheit (21 degrees Celsius). Protecting the plant from sudden temperature fluctuations and cold drafts is also important for its well-being.
Fertilizing
During the active growing seasons of spring and summer, fertilize Spath Domino every 4 to 6 weeks with a balanced houseplant fertilizer. Diluting the fertilizer to half strength can prevent nutrient burn. Reduce or cease fertilization during the fall and winter months when the plant’s growth naturally slows down.
Common Problems and Solutions
Yellowing leaves on a Spath Domino can indicate either overwatering or underwatering; checking the soil moisture before watering helps differentiate the cause. Brown leaf tips often point to low humidity or an accumulation of fluoride from tap water. Increasing ambient humidity and using filtered water can alleviate this issue. If the plant is not flowering, it may be receiving insufficient light, as Peace Lilies require adequate light to produce their characteristic blooms. Common pests like spider mites and mealybugs can be addressed by wiping the leaves with a damp cloth or applying insecticidal soap as needed.
Repotting and Propagation
Repotting Spath Domino is typically necessary when the plant becomes root-bound, indicated by roots circling the drainage holes or emerging from the soil surface. This usually occurs every one to two years. Choose a pot that is only one or two inches larger in diameter than the current one and use fresh, well-draining potting mix. The best time for repotting is during the spring or early summer.
Spath Domino is most effectively propagated through division. Carefully remove the plant from its pot and gently separate the root ball into smaller sections, ensuring each section has a portion of the root system and at least a few leaves. Plant these divisions into individual pots with fresh soil, providing them with consistent moisture and indirect light as they establish.
Safety Considerations
Spath Domino, like other Peace Lilies, contains calcium oxalate crystals, which can cause irritation if ingested. This plant should be kept out of reach of curious children and pets to prevent oral irritation, swelling, and digestive upset. While generally not life-threatening, ingestion can lead to discomfort.
