Peace Lilies are very common house plants because they are easy to grow. They can grow up to 16 inches, but larger ones can often reach 6 feet tall. Peace Lilies produce white flowers in the early summer and continue to bloom throughout the year.
The Peace Lily is related to other aroids, including anthurium and alocasia. The plant has glossy, pointed and oval leaves that emerge from the soil. Typical of the aroids, the white flowers emerge from the leaf stalk surrounded by a cupped white spathe that gradually fades from pure white to greenish or yellow over time. The central spadix is white or yellow. These plants are native to the rainforests of Central and South America.
Light: They are shade-loving plants in their native habitats, and in the home they prefer light to moderate shade. Some varieties can withstand more light.
Water: During the summer, water and mist frequently. They thrive with higher humidity. In water, reduce watering, but never allow the soil to dry out.
Temperature: They really prefer moist warmth; avoid cold drafts and temperatures below 55ºF if possible.
Soil: These plants like a rich, loose potting soil containing plenty of organic material.
Fertilizer: Feed weekly in the summer, or use slow-release pellets at the beginning of the season.
Peace Lilies are easy to propagate by division during repotting.
Annually, in the spring or as needed. Large plants can be divided into clumps, which can then be independently potted. Always use high quality potting soil.
Peace Lilies have been heavily hybridized, and there are currently dozens of varieties available. They range from miniature to massive, from deep green with snow-white flowers to golden-leaved beauties. Some of the hybrids include:
- S. Mauna Loa. A larger plant, up to 2 feet
- S. Mojo. A striking, large plant with vibrant green leaves
- S. Golden Delicious. The new growth is golden-green
- S. Starlight. The narrow leaves on this plant have wavy margins. The plant is known for heavy, multiple blooms, with as many as 20 flowers on a single plant.
The Peace Lily is a striking plant when used in a massed display. They bloom in the spring with long-lasting flowers that hover gracefully over the leaves on thin stalks, although they can be forced to bloom in the fall or winter. A very well-grown Peace Lily may bloom twice a year, resulting in several months of flowers. All spathiphyllum are vulnerable to bugs including aphids, mites and scale, as well as root rot if they are allowed to sit in water. Curled, pale leaves generally indicate too much light. Scorched leaves indicate direct sun. Plants that are not properly fertilized may fail to bloom.
