Peace lilies
Botanical name: Spathiphyllum
Peace lilies (Spathiphyllum wallisii) are popular houseplants with distinctive white flower-like spathes that stand above the glossy tropical foliage. Easy to grow and happy in indirect light, they make elegant additions to any home.
Looks
Peace lilies form a clump of glossy dark green leaves, 30–60cm (1–2ft) tall. Their ‘flowers’ comprise a flamboyant white petal-like spathe that surrounds a central cream-coloured spike (spadix). These stand above the leaves to create a striking display that lasts for several months. The spathes turn greener as they age.
Likes
They like consistent warmth and moderate humidity – a bathroom is an ideal location for them. They prefer rainwater to tap water. For good growth and flowering, feed every two weeks from spring to autumn. Wipe the leaves with a damp cloth to remove dust and improve photosynthesis.
Dislikes
Very dry air can cause leaf browning – mist plants regularly or stand them on a tray of damp gravel, and keep them away from hot radiators and cold draughts. The roots can rot if the compost is damp for long periods, so take care not to overwater. Direct summer sunshine can scorch the foliage. Plants can droop dramatically when they need watering, but soon perk up after a good drink.
Did you know?
Peace lilies are members of the arum family and, like many of their relatives, are poisonous, so keep them out of reach of children and pets. Also wear gloves when handling them, as the sap can cause skin irritation.
