Peace lilies (Spathiphyllum) are popular houseplants known for their striking white spathes and deep green foliage. While many varieties are compact, larger peace lily cultivars offer a dramatic presence, creating a lush, tropical feel and significant visual impact in indoor spaces.
Understanding Big Peace Lily Varieties
Large peace lilies typically reach heights and widths ranging from three to six feet when mature. They are characterized by expansive leaves and larger, more prominent white spathes. Several cultivars are recognized for their impressive size and robust growth:
‘Sensation’ grows up to six feet tall with broad, deeply ribbed leaves.
‘Mauna Loa’ is known for abundant white blooms and reaches three to four feet.
‘Domino’ features variegated foliage with white or cream splashes.
‘Giant Spathiphyllum’ refers to a group of very large cultivars.
Essential Care for Large Peace Lilies
Large peace lilies require consistent attention to light, water, and humidity to maintain their luxuriant foliage and characteristic blooms.
Light Requirements
Large peace lilies prefer bright, indirect light. Too little light may result in fewer blooms and less vigorous growth. Direct sunlight should be avoided, as it can scorch their broad leaves. Positioning them near a north or east-facing window, or several feet away from a south or west-facing window, provides suitable illumination.
Watering Needs
Large peace lilies have significant water requirements. Keep the soil consistently moist but not waterlogged, as saturation can lead to root rot. Water when the top inch or two of soil feels dry, or when the plant begins to droop. Pour water until it drains from the bottom of the pot.
Soil and Potting
A well-draining, rich potting mix is crucial. A blend containing peat moss, perlite, and pine bark provides good aeration and moisture retention. Due to their size, these plants require sturdy pots to support their weight and root system. Heavy ceramic or terracotta pots are preferred to prevent tipping as the plant grows.
Temperature and Humidity
Peace lilies thrive in warm, stable temperatures, ideally between 65-80°F (18-27°C). They are sensitive to cold drafts, which can cause leaf damage and stunt growth. High humidity, above 50%, is beneficial for their foliage, helping to prevent brown leaf tips. Misting the leaves regularly or placing the pot on a pebble tray filled with water increases humidity.
Fertilization
During the active growing season (spring through summer), large peace lilies benefit from regular fertilization. Apply a balanced liquid houseplant fertilizer, diluted to half strength, every two to four weeks. Reducing or ceasing fertilization during fall and winter allows the plant to rest, preventing nutrient buildup harming the roots. Over-fertilization can lead to salt accumulation and burning the roots.
Repotting and Space Considerations
Repotting a large peace lily is necessary every one to two years, or when the plant becomes visibly root-bound, indicated by roots circling the pot or emerging from drainage holes. When repotting, select a new container only one to two inches larger in diameter than the previous one to avoid overwatering issues. These plants demand ample physical space to accommodate their mature spread, ensuring they do not feel cramped or impede walkways.
Troubleshooting Common Issues
Despite diligent care, large peace lilies can encounter common problems, often related to environmental conditions. Addressing these issues promptly helps maintain the plant’s health.
Yellowing leaves often indicate overwatering or a nutrient deficiency. If the soil is consistently soggy, allow it to dry out more between waterings to prevent root rot. Brown leaf tips often signal low humidity or exposure to fluoride in tap water. Using filtered water or increasing humidity alleviates this issue.
Drooping leaves usually signal thirst, indicating immediate watering is needed. However, persistent drooping coupled with wet soil might point to root rot, requiring inspection and potential repotting into fresh, drier soil. A lack of blooms, especially in mature plants, often suggests insufficient light, prompting a move to a brighter location.
Maximizing Your Big Peace Lily’s Impact
A large peace lily serves as a focal point in a room, enhancing its aesthetic appeal. Strategic placement highlights its impressive size and lush foliage. Position the plant in a prominent corner or against a wall where its expansive reach is appreciated without obstructing movement.
Maintaining clean leaves is important for appearance and health. Dust can accumulate on leaf surfaces, hindering photosynthesis. Gently wipe the leaves with a damp cloth every few weeks to keep them dust-free and maintain luster. Regularly removing spent blooms or yellowed, damaged leaves contributes to the plant’s appearance and directs energy towards new growth.
