The reason why people have plants in the shower is to improve the air quality and provide benefits for other plants and create a spa like atmosphere in the bathroom and increase humidity and also as a way to wash off leaves and soil of the plants.
The humidity of the shower can also mimic the natural environments that some plants live and thrive in and it can also be a great way to clean the plants and also flush out any excess minerals that are in the soil of the plants.
Misting the plants also helps with humidity and showering the plants is done often for cleaning.
The plants that should not be put in the bathroom are plants that require lots of sunlight such as Gardenia plants, Ponytail palm plants, Hibiscus plants, Jade Plants and Strelitzia plants as these plants are not suitable for the often dimly lit and humid environment that are in bathrooms.
Also plants such as the Euphorbia Candelabrum which require dry conditions during winter would also struggle in the humidity of a bathroom.
The best plant to put in the bathroom are Fern plants such as the Boston Fern.
Boston Ferns are a great choice of plant to put in the bathroom due to their ability to thrive and live well in humid conditions, which is typical in bathrooms.
Boston ferns are also low in maintenance and are a great plant option for beginners.
Other good plants to put in the bathroom are Potho plants such as the Marble Queen which is hardy and air purifying and Orchids and peace lilies which are also popular plants for the bathroom as they are low maintenance and have the ability to tolerate humidity well.
The Flamingo flower and the rubber plant are also good bathroom plants.
The temperature that is too hot outside for houseplants are temperatures above 80 F, especially if the houseplants are in confined spaces.
Temperatures that get above 90 F for houseplants can cause heat stress and is considered a heat stress baseline for most plants including houseplants.
Any prolonged exposure to the high temperatures for the houseplants and some other plants can cause leaf wilting, weakened plant immune systems and decreased flower production.
Some plants can tolerate higher temperatures at least for a short while but it's best to keep the houseplants and other plants out of extreme heat if possible.
If you have outdoor plants and they are out in extreme heat it's best to allow them to be in some shade during extreme heat and ensure they get enough water but not too much water.
For some houseplants even temperatures that are consistently above 75 F can be considered too hot or too warm.
And prolonged exposure to temperatures above 85 F to 90 F or higher can cause heat stress in the houseplants and other plants.
You also don't want the houseplants to get too cold and the temperature of the house should stay above 50 F.
Also if you want to place the houseplants outside for awhile you should make sure the outdoor temperature stays consistently above 50 F.
And if nighttime temperatures are forecast to fall below 50 F you should bring the houseplants back in for the night and then bring then outside again if you want to do so when the temperatures rise again.
