Taxonomy and naming

Spathiphyllum is a genus within the arum family Araceae. The common name 'peace lily' is widely used for the genus and especially for cultivated houseplant forms, though it is not a true lily.

In Canada, peace lilies are common indoor ornamental plants valued for their low-maintenance growth and decorative foliage.

Description

Spathiphyllum species are herbaceous, typically perennial plants with glossy leaves and a distinctive inflorescence consisting of a spadix surrounded by a spathe. The spathe is often white in cultivated plants, giving rise to the common name.
