A single leaf of Philodendron gloriosum, one of many plants that purify inside air.
Indoor plants make great air purifiers in the way of absorbing the carbon dioxide in the air and giving off oxygen in the photosynthesis process. Especially this time of year, when many of us are stuck inside with dry indoor heat and the snow outside has buried any semblance of green vegetation.
Finally, think lots of leaf surface. The Alocasia sp. Zebrina gets relatively large leaves and has an attractive striping on the stem.
This large elephant ear known as colocasias esculenta 'Thailand Giant Strain' is extraordinary in its leaf size and structure. Let's just say one plant this large would take care of your entire household clean air needs. Notice our son, Elijah when he was 12 years old, amongst the leaves. This was grown outside for one season but can easily grow inside in a pot if you have the space and full sun exposure.
