Acer oblongum is also reported to be suitable for growing at higher elevations in Oatacamund and Coonoor in the Nilgiri hills. The bark is white or green and leaves are oblong or ovate, about 5-17 cm with long petioles. The twigs are red-brown or purpulish. The greenish white flowers are small and measure about 4 mm in diameter. Acer oblongum seeds require cold stratification for 2 to 4 months at about 1-8°C for successful germination. Successively the seeds are planted in moist soil in individual pots, where germination may take several weeks. Maple species in Himalaya remain green all the winter and this is the unique thing among maple family. Acer oblongum prefers partly shaded exposure, with well drained acid or neutral soils.
