Trident maple scientifically known as Acer buergerianum is a species of maple belonging to Aceraceae (Maple family). The plant is native to eastern China (from Shandong west to southeastern Gansu, south to Guangdong, and southwest to Sichuan), Taiwan and Japan. Apart from Trident maple, it is popularly known as Taiwan Trident Maple and three-toothed maple. Genus name is the Latin name for a maple tree. The species name honors Heinrich Buerger, the 19th-century German botanist.

Plant Description

Trident maple is a small to medium-sized, spreading deciduous tree that normally grows about 5–20 m tall with a trunk up to 50 cm diameter. The plant can be planted in full sun or partial shade on any well-drained, acid soil and is quite tolerant of salt, air pollution, wind, and drought. It performs well in urban areas where soils are often poor and compacted. Take care to plant the bud union above the soil level. Water in well and keep the soil moist until tree is established. Fertilize when planting and again after new growth appears. Prune trees when planting to encourage new growth. Twigs are slender, flexible, reddish-brown with gray pubescence. Buds are conical, reddish-brown sharp-pointed. The bark is scaly and exfoliating on larger stems, gray outer bark flakes off, revealing lighter reddish-brown patches.
