Aglaonema are grown for patterned foliage in silver, cream, pink and deep red. They are unusual in keeping that colour in conditions where most variegated plants revert to plain green.
What every Aglaonema wants
Medium to low light. The darker green varieties tolerate genuinely dim corners, while the pink and red ones need more light to hold their colour.
They grow slowly, want to dry out slightly between waterings, and cope with ordinary household humidity. Cold is the main thing they will not forgive. Below about 15°C (59°F) the leaves develop dark, greasy-looking patches that do not recover.
Aglaonema are toxic to cats and dogs.
