Spathiphyllum Wallisii “Peace Lily”

Spa wal 12 Spathiphyllum wallisii Peace Lily foli8

The Peace Lily is a vigorous plant with large, long, glossy, leaves. Officially known as Spathiphyllum wallisii, the leaves typically have a deep green color, which contrasts sharply with the pure white, arum-like flowers that are borne on slender stems. Each flower may grow up to fifteen centimeters long, contains a creamy-white, maize-like spadix and turns green with age.

There are over 50 species of Spathiphyllum, although Spathiphyllum wallisii is the most common indoor plant. Plant breeders have produced many varieties and hybrids, including giants such as “Mauna Loa” and “Sensation” as well as variegated types (that look as if they have been kept too close to a clumsy house painter).

All Spathiphyllums do well in poor light and can tolerate occasional over watering and are ideal for novice houseplant keepers. Research conducted by NASA found the Peace Lily to be one of the top indoor plants for its air-cleansing abilities.

Light

Low to medium light. Avoid direct sunlight as it will damage the leaves.

Watering

This is a thirsty plant so the growing medium should be kept moist at all times. Under-watering causes the plant to wilt although it usually recovers quite well when re-watered.

Pruning

This plant cannot be pruned. Dead leaves and spent flowers should be removed at their bases with a sharp knife or pruning shears.

Feeding

Diluted fertilizer should be added to the water at every watering.

Pest & Diseases

Generally pest free, but keep a lookout for mealybugs. These should be removed by cleaning with a damp cloth or paper towel. Two-spotted spider mites may also affect the plant, especially if stressed or in bright, dry environments.
