Winter mold, mustiness and damp in the home are caused by excess humidity. The problem happens in warm, muggy regions too. Dehumidifiers and other solutions can have some effect but plants are a prettier, more natural way to remove some of the clammy air and damp ambiance. Humidity absorbing houseplants serve dual purpose as they harvest the moisture they need from the air and bring the outdoors in.

Reducing Humidity with Plants

Using plants in the home can be useful in many ways. One of the more interesting is their use as dehumidifiers. What plants absorb humidity? Actually, most plants harvest some moisture from the air through their leaves, but a few are extremely efficient at the process and take much of their moisture through their leaves. This is good news since high moisture levels in the home can be associated with respiratory problems and threaten the structure of your house.

You may wonder how plants can reduce humidity in the home. The answer is found in a plant’s foliar uptake. This is its ability to absorb dew, fog or other forms of vaporous moisture through the stoma in the leaves. This moisture moves into the xylem and then down the roots.

Plants that like moist soil are more likely to evolve this adaptation, but some plants in arid areas with little rainfall may also be able to process moisture in this manner. Therefore, if you pick the right plants that absorb humidity, you can reduce the excess ambient moisture in your home and prevent mold and mildew issues.

What Plants Absorb Humidity?

Unless you are going for a rainforest effect in the home, too much damp, sticky air does not produce the tropical sultry tones found in such places. In fact, you are more likely to have musty curtains and other fabrics, clammy surfaces and weeping walls.

The peace lily is one attractive foliar plant with an interesting spathe that will help reduce moisture in the air. Classic Victorian era plants such as English ivy, parlor palm and Boston fern provide elegant notes to décor while removing some of that stickiness from the air. It is possible that reducing humidity with plants like these can help keep excess moisture from the air and possibly save your sagging wallpaper and musty back room.

The plants listed above all tolerate or crave moisture but a surprise plant for reducing humidity is Tillandsia, which cannot tolerate excess moisture at all. However, it absorbs most of its moisture from the air, making it great for absorbing humidity. This is because it is an epiphyte and does not live in soil. Instead, the plant attaches to a log or rock, inserts itself into a tree crotch or snuggles into a crevasse.

This little plant is also called air plant because of its epiphytic nature and ability to live in a soilless situation and still feed and water itself. The fun part about Tillandsia is the many forms, some of which have bright flowers. You can also mount Tillandsia on many different media or simply place them in a decorative bowl or directly on a shelf. They are easy to care for and may eventually produce little pups that you can divide, making even more humidity absorbing houseplants.
