While the glossy green leaves are gorgeous, the real appeal of this tropical plant is in its graceful white spathes that resemble flowers. According to Luke Dejahang, gardening expert and CEO of Crown Pavilions, one of the key mistakes people make is underestimating just how much light a peace lily really needs to flower.

Dejahang told Express.co.uk to "position your peace lily in bright, indirect light". He elaborated: "While the peace lily can tolerate low light, it will flower more readily and flourish with sufficient light." And one of the best places to find that kind of light – paired with humidity – is in the bathroom, especially one with a frosted window.

Bathrooms, according to Dejahang, naturally create the high-humidity environment peace lilies crave, making them one of the ideal spots in the home to help trigger flowering.

High humidity environments mimic the plant's native tropical conditions and keeps the leaves vibrant while encouraging those sought-after white spathes.

But if you don't have a bathroom with a window, it's best to increase humidity levels by misting the leaves regularly or use a humidifier.

Dejahang also pointed out the importance of a consistent temperature to encourage the plant to bloom.

He said: "Maintain a stable temperature between 18 to 27 degrees, and make sure to avoid cold drafts and hot radiators as sudden temperature changes can stress the plant."

When it comes to the watering schedule, Dejahang advised being attentive but careful.

He advised: "Water lightly when the top inch of soil feels dry, as you want to ensure the soil is kept consistently moist but not waterlogged."

Dejahang also warned against using cold water straight from the tap, encouraging people to use "room temperature water" instead.

Peace lilies may also need a little feeding boost to get them going again in the blooming season, which is now.

"Apply a balanced, water-soluble fertiliser for houseplants," said Dejahang. "Or even a quick boost of tea or coffee that can instantly give your peace lily so much energy."

This caffeine kick can act as a gentle stimulant for the plant, though it should always be well diluted and only used occasionally.

If you have a peace lily that has drooping leaves, brown tips, or a lack of blooms, it could be a clue that the plant isn't getting the humidity, warmth or light it needs.
