Today, we bought some Dieffenbachia (aka Air Purifier) plants. It is great as an indoor plant. Studies have shown that indoor plants can remove up to 80% of indoor air pollutants. Therefore, it's important and really inexpensive to have a couple of indoor plants to keep the air clean.
Watering the plants will be the kids' responsibility. In other words, I will be doing most of the plant care. I don't mind, gardening and caring for plants can be very therapeutic sometimes.
