Spathiphyllum wallisii (Peace Lily)

Spathiphyllum wallisi is an extremely resilient plant with charming foliage and generous blooms. Its elegance makes it a versatile design element, and it is easy to love as a plant. Some believe that it adds a sense of peacefulness to a space, and I must say I agree. There’s something inexplicably peaceful about this plant. Much like many of its kin in the Araceae family, the Spathiphyllum wallisi is a favourite among indoor gardeners. As per usual, I’ll be covering its viability as a design element in your space, as well as how to care for it.

Is this right for my space?

Peace lilies generally need very little light, so they’ll fit right in in almost any part of the home. However, you should avoid putting them right in front of a west or south facing window, even with a sheer curtain. The heat will cause the leaves to droop, as well as burning the delicate white flowers.

As a design element, they definitely need their own space to shine. The contrast of the dark green foliage and the white spathes (“flowers”) is already very interesting to look at, and the plant fans outward, occupying a lot of space. Their leaves also have striations, adding texture to their appearance. Therefore, Peace Lilies need their own space to show off, but if you’re short on space, you can definitely pair it with a few more plants, preferably those with darker foliage or those with white on their leaves too. This will create a sense of unity. To encourage simplicity, I would recommend using a white pot.

Here, the dark green of the Phalaenopsis orchid ties in well with the Peace Lily’s foliage, as does the lighter green pot. The White stripes of the Haworthia coordinate with the pot and spathes, while the cream-beige cover pot goes with the spadix of the peace lily.

How should I care for my Peace Lily?

Watering: Like many other members of the Araceae family, Peace Lilies prefer to dry out between watering just a little. Luckily for us, Peace Lilies happen to be extremely good at telling us when they need water. They’ll droop noticeably when in need of water. When they do this, give them a thorough watering, and allow them to drain. To avoid tip browning, use soft water.

Light: Peace lilies prefer medium indirect sunlight. That is, place them around 2 meters away from a west or south facing window, and definitely do not give them direct sunlight. They will do well in a north or east facing window.

Fertilising: These bad boyes love a good balanced liquid houseplant fertiliser around once a month. However, it would be wise to dilute a little, especially to begin with.

General care tips:

  • If you see brown spots on flowers, move it further away from any source of light and heat
  • While Peace Lilies love humidity, try to avoid misting them. Water on the leaves encourages powdery white mildew to grow on the leaves of your Peace Lily. This can stunt the growth of new leaves and stop the plant from flowering.
  • If you do happen to get powdery white mildew on the leaves, choose a sunny day to move your Peace Lily outside, and thoroughly spray the plant with a mixture of water and milk. The fats in the milk along will burn away the mildew when exposed to the sun. You may need to repeat this one or two times. Hose the plant down and allow it to sit in the sun for a bit after that to avoid bringing the smell of old milk into your house.
  • If it requires watering every day or every second day despite being in a plastic pot, it’s time to repot.
  • Dust the leaves every now and then, as the larger ones will get dusty.
  • Losing a small, older leaf every now and then is totally natural.
  • A Peace Lily should perk up around half an hour or so after being watered. If you water it and it hasn’t perked up after a day, it might have root rot.
  • Spathes turn green as they age. This is totally normal.
