In the garden

Spathiphyllum 'Mauna Loa Supreme' performs as a conservatory or indoor specimen where humidity and steady temperatures can be maintained. Its clump-forming habit produces a clear structure in a pot or container, making it straightforward to site in a greenhouse shelf or on the floor of a heated conservatory. Expect the seasonal flowers between May and September when provided with light conditions that avoid harsh, direct sun. Grow it in a neutral, loam-based medium that retains moisture without waterlogging; the soil should be kept moist but well drained. Give the plant partial shade and a sheltered aspect — south- or east-facing glass is ideal — to supply bright, indirect light without exposure to cold draughts. The H1b classification indicates the plant is tender in UK terms and should be kept under cover or brought indoors before the first frost rather than left outside through winter. As a houseplant, place Spathiphyllum 'Mauna Loa Supreme' where its clump and summer blooms can be appreciated close to seating areas in a conservatory or large room. Its combination of evergreen foliage and a May–September flowering season suits display on the ground or on a low stand where the flowering period is immediately visible.
