Three indoor plants that thrive in water and clean the air, adding charm to any space
Bringing nature indoors brightens a room and has practical benefits too, such as helping to purify the air. Houseplants add colour and style to any space. Three species in particular do well grown in water, help improve indoor air quality, and need very little fuss: Pothos, Lucky Bamboo, and Spider Plant.
Pothos, a resilient choice
The Pothos, Epipremnum aureum, is a household favourite. It adapts quickly and grows fast with little effort, which makes it suitable for people new to indoor gardening. Pothos tolerates low light, although indirect light is best for growth. To grow it in water, place a cutting into a clear container of clean water and change the water every 7 to 10 days to keep the plant healthy. Studies indicate Pothos can help remove some airborne compounds, which can make indoor air feel fresher.
Lucky Bamboo, sleek and simple
Lucky Bamboo, Dracaena sanderiana, has a clean, minimalist look that suits modern homes. Often kept for decorative reasons, it fits small spaces and is relatively hardy. When growing Lucky Bamboo in water, use filtered or rested water (left to stand so chlorine can dissipate), keep the roots submerged and avoid direct sunlight. It is well suited to minimalist décor and adds a simple, restrained touch to interiors.
Spider plant, hardy and easy to propagate
The Spider Plant, locally known as “malamadre”, Chlorophytum comosum, is known for producing pups (offshoots) that are easy to propagate. It is resilient, thrives in a range of conditions and looks good on shelves or in hanging planters. For water cultivation, put the plant’s offshoots in water and change that water regularly to keep them vigorous. Like Pothos, research associates the Spider Plant with air-purifying properties, which can help create a healthier indoor atmosphere.
What the science says and practical benefits
Research, including studies by NASA, has shown how these plants can improve indoor air quality. However, their effect is modest and they should not be seen as a replacement for proper ventilation. Their main benefits are visual and environmental: they make spaces more attractive while providing a modest reduction in airborne compounds.
Keeping your water-grown plants healthy
Regular water changes are key to longevity. Clean containers thoroughly to prevent fungus and smells. Glass containers are handy because you can easily keep an eye on root growth. Don’t leave water stagnant for long periods if you want the plants to thrive.
Common mistakes to avoid
There are a few pitfalls that can harm water-grown plants. Failing to change the water regularly can lead to bacterial build-up, bad smells and root problems. These plants need good indirect light; placing them in very dark spots can slow growth and cause leaf discolouration. Water quality matters too; avoid high-chlorine tap water by letting it stand or using a filter, especially for Lucky Bamboo. Keep an eye on the roots and act quickly if you see browning or softening.
Following these care tips will help keep your home filled with thriving, decorative and environmentally friendly plants. Water-grown indoor plants bring a distinctive look to your space and play a modest part in purifying indoor air, encouraging a fresher, more pleasant living environment.
