Aglaonema pictum
A small Sumatran Aglaonema, 30–50 cm tall, with dull, often crinkle-edged leaves blotched in patches of dark green, light green and silver. Three-coloured plants are sold as 'Tricolor'. Unlike most of the genus it is a mountain plant: Nicolson gives the slopes of Sumatran volcanoes, usually at 1000–2000 m. That means it wants cooler, more humid conditions than a typical Chinese evergreen. A humid enclosure with mild days and cool nights is the closest match to its habitat.
Where it grows wild
It grows on the forest floor on the slopes of major volcanoes in Sumatra and Nias. Stems are erect and fairly slender. Nicolson notes that seasonality in flowering is weak and probably varies with the exposure of the mountainside.
Usually 1000–2000 m on volcanic slopes. It is occasionally collected lower, down to 35 m near Padang. A dated GBIF specimen from Gunung Mamas in the Leuser reserve records 950 m.
