Spathiphyllum 'Clevelandii' or Peace Lily is a freely flowering form of Spathiphyllum of unknown origins. Leaf blades are narrow to 1 foot (0.3 m) long and 2.5 inches (6 cm) wide, acuminate at both ends. Petioles are slender and longer than the leaf blades. The leaves arise from short stout underground rhizomes. They are a great flowering plant for interior decoration and the plant provides long lasting cut flowers. This is a very easy plant to grow.
Blooming Time: Spathes are borne well above the foliage, erect, ovate to 6 inches (15 cm) long and white. The spadix is stalked, up to 2 inches (5 cm) long with the pistils exerted. Flowers are fragrant.
Culture: Spathiphyllum 'Clevelandii' or Peace Lily needs partial shade to full shade and a rich, well-drained soil mix. In the greenhouse, we use a soil mix consisting of 2 parts peat moss to 1 part loam to 2 parts sand or perlite. To the mix, we add 14-14-14 osmocote to help keep the plants dark green and to stimulate flowering. Plants are well-watered and allowed to dry slightly before watering again. We fertilize the plants weekly with a balanced fertilizer diluted to 1/2 the strength recommended on the label. Plants are moderately fast growing and should be re-potted on a yearly basis, which we usually do during the winter months.
Propagation: Spathiphyllum 'Clevelandii' or Peace Lily is propagated by division. This can be done at any time of the year.
Spathiphyllum 'Clevelandii' was featured as Plant of the Week September 10-23, 2010.
