Every living space offers plenty of opportunities to get creative with plants and it is not just the visual aspect.
Myriad studies have shown that there are psychological benefits to having plants in indoor spaces and some of them are lowering stress levels, boosting mental wellbeing, improving mood, helping us to be more productive, and instilling a more calming atmosphere. Some plants even help to purify the air by filtering harmful pollutants.
It is even better if the indoor plants you select are non-toxic, so they pose no risk to children and pets.
Here are 30 non-toxic house plants, some of which help to purify the air, others add an extra sensory dimension and a fragrant welcome, both contributing to mindfulness, senses, and wellbeing.
