Spathiphyllum x 'Wallisii' Dwarf Peace Lily1

Edward F. Gilman 2

Introduction

Dwarf peace lily is a 12- to 15-inch-tall plant that is upright in form (Fig. 1). The shiny, dark green leaves of the dwarf peace lily give this plant its charm. These 10-inch-long, arching leaves have puckered veins that impart a rippled or puckered effect. Small, chalk white flowers are packed on a spadix borne in front of an attractive white spathe. These flowers occur in the spring and are followed by mostly inconspicuous, berry-like fruits.

Use this plant in a partially or fully shaded location in the landscape. The dwarf peace lily prefers rich, well-drained soils that are relatively acidic. It has no salt tolerance and favors warm temperatures. Fertilize this plant regularly during the growing season to maintain a dark green foliage color.
