Now that I have my own garden, I started collecting aglaonemas, which turns out to have an even bigger number of varieties and cultivars. They are a member of the aroid family (Araceae) just as alocasias, anthuriums, philodendrons, and xanthosomas. Also, despite them being given the popular English name of Chinese Evergreens, they are actually endemic to the Philippines, particularly to Luzon.
They thrive best in filtered sunlight: too much and the leaves will burn while too little will not bring out the patterns and the colors. I place them under big philodendrons as proportionately-big ground covers and to offset each others' leaf shapes and patterns.
They would also look good as potted specimens and do well as indoor plants. Moreover, most of them have unusually-colored or patterned stems, all the more it is best placed on a tabletop to better appreciate the plant.
