In the garden
Spathiphyllum 'Cissy' sits in the arum family (Araceae) and belongs to a genus that originates from tropical regions of the Americas and southeastern Asia. As a clump-forming evergreen it is raised for its glossy foliage and the characteristic spathe-and-spadix flowers that appear in the growing season from May to September. Position 'Cissy' where it receives partial shade — bright, indirect light from a south- or east-facing window suits it well, provided direct sun is avoided. Rooting medium should be a loam-based mix at neutral pH that stays moist but not waterlogged; good drainage is essential. The plant’s UK hardiness is H1b, meaning it must be kept under glass or indoors and is not suitable for unheated outdoor planting. As a houseplant or conservatory specimen it performs best in a sheltered spot out of cold drafts. A sheltered south- or east-facing conservatory will allow it to flower reliably during May to September. When individual spathes fade, cut them back to the base of the stem to keep the clump neat and to encourage subsequent flowering.
