About

Spathiphyllum 'Sweet Silvana' is an evergreen, clump-forming houseplant in the Araceae grown for indoor and conservatory display. It suits a bright spot out of direct sun and produces flowers from May to September. The cultivar prefers neutral loam that stays moist but drains well and thrives in a south- or east-facing, sheltered position. Hardiness is H1b (tender), so it is normally kept indoors or in a heated glasshouse through the winter.

In the garden

A cultivar within the genus Spathiphyllum and family Araceae, 'Sweet Silvana' is offered for conservatory, greenhouse and indoor use where evergreen foliage forms neat clumps. It is listed for those specific environments rather than outdoor planting in unprotected UK borders, and is valued where shelter and controlled conditions are available. Position plants where they receive partial shade: bright, indirect light is appropriate and an east- or south-facing, sheltered aspect is recommended for windows or glasshouses. Use a loam-based substrate at neutral pH that remains moist but is free-draining; the aim is even moisture rather than waterlogging. H1b hardiness means the cultivar is tender and should stay in heated or indoor environments over winter rather than being left outside during cold spells. As a houseplant or conservatory specimen it suits display beside seating areas or where taller foliage is needed to soften interiors. Keep the crown above freely draining compost and avoid full sun on south-facing windows unless filtered; expect seasonal flowering between May and September that rises clear of the leaves.
