Alright, so, I’ve been messing around with my plants again – specifically, my white anthurium and peace lily. These guys are supposed to be pretty chill, but I wanted to see just how chill they really are when it comes to temperature.
First off, I got my hands on a couple of thermometers – one for the soil and one for the air. I placed each plant in a different spot in my living room. The anthurium got a spot near the window where it’s a bit brighter and can get a little warmer during the day, and the peace lily went to a shadier corner that stays more consistently cool.

For a week, I tracked the temperature in both locations at different times of the day – morning, afternoon, and night. I also checked the soil temperature to see how much it changed compared to the air. Gotta say, those soil thermometers are pretty handy. I noted down all the readings in my little gardening notebook.
Here’s the Gist of What I Found:
- Mornings: Both spots were pretty cool in the morning, usually around 65°F (18°C). The soil was a degree or two cooler.
- Afternoons: The spot by the window definitely warmed up. The air temperature hit around 75°F (24°C) a few times. The anthurium seemed to like it. The peace lily’s spot stayed closer to 70°F (21°C), and the soil temperature only went up by a couple of degrees in both locations.
- Nights: Things cooled down again, back to around 65°F (18°C) in both spots.
After a week of this, both plants were still looking good. The anthurium had a new leaf unfurling, and the peace lily’s leaves were all perky. No signs of stress from the temperature changes. It seems like they can handle a decent range, as long as it’s not too drastic or for too long.
I decided to push it a little further. I moved the anthurium to the balcony for a couple of hours during the warmest part of the day when it was hitting close to 80°F (27°C). It did fine for that short time, but I wouldn’t leave it out there all day. I also left the peace lily in a cooler room, around 60°F (16°C) overnight. It didn’t seem to mind the slight chill.
So, what did I learn? These plants are tougher than they look! They can tolerate some temperature ups and downs, but they do best in that sweet spot of 65-75°F (18-24°C). I’m going to keep an eye on them and see how they do as the seasons change, but for now, I’m pretty happy with my little temperature experiment.
