Peace Lily   (Spathiphyllum wallisii)

Peace Lilies are native to tropical regions of the Americas and southeast Asia. They are evergreen, herbaceous perennials with broad, dark green leaves emerging from the ground on short stems. Their blooms are conical clumps of small flowers borne on a stalk surrounded by a large white or greenish bract.  This gives the appearance of a large flower.  At bloom time they have a look that is reminiscent of Calla Lilies (Zantedeschia).

Plant Care

Propagate from the seed. Sow on sphagnum moss in spring, or when ripe at 73-81°F (23-27°C). Can also propagate by division in winter to early spring or right after the flowering.

Plant Growth:

Evergreen perennials. Large dark green leaves on stalks that rise directly from soil. Good in pots, 1.5-6 feet tall, depending on species.

Grows best in deep shade with high humidity. If not located in warm regions, plant Spathiphyllum in a warm greenhouse or conservatory. Otherwise, species work well in a humid, shady border. Some make nice houseplants.


Flowers resemble Calla Lily, a central column of tiny, closely set flowers surrounded by a leaf-like bract.

Soil and Irrigation:

Needs regular water to thrive; however, Peace Lilies can wilt very badly and still recover with a thorough watering.


Peace Lilies don't need much fertilization to survive, but dilute liquid feedings with a complete fertilizer promotes darker leaves and more floral blooms.


Pull off dead leaves and flowers by pulling them from their bases. Don't pull the dead plant parts straight up as you generally will not get a clean break. Instead grab the base of the dead leaf or flower and pull them from side to side in a 90° angle from the rest of the leaves.


Root rot, bacterial soft rot, and leaf spots are common problems.
