Description
Acer ginnala, commonly known as Amur Maple, is a small deciduous tree or large multi-stemmed shrub typically growing to 15-20 feet tall. It features smooth gray-brown bark, small fragrant yellowish-white flowers arranged in clusters in spring, and distinctive winged samaras that often turn a striking red before maturing. It is widely appreciated for its exceptional fiery autumn foliage and dense, rounded canopy.
Key Features
Distinctive three-lobed leaves where the central (terminal) lobe is significantly longer than the side lobes, doubly serrate margins, opposite leaf arrangement, and winged paired samaras with parallel or slightly divergent wings
Habitat
Found naturally in river valleys, thickets, and mountain slopes; highly adaptable, tolerating various soils, urban pollution, and cold climates, preferring full sun to partial shade
Geographic Range
Native to northeastern Asia including China, Mongolia, Korea, eastern Siberia, and Japan; widely planted as an ornamental across North America and Europe, where it can occasionally escape cultivation
Condition Notes
The specimen is in Good health condition, showing a complete blade, standard green coloration, minor drying typical of a pressed herbarium specimen, and no visible major disease or insect damage
Interesting Facts
Named after the native Tungus name for the tree, Amur maples are extremely hardy and were introduced to Western horticulture in the mid-19th century. They are frequently used in bonsai cultivation due to their small leaves and adaptability to pruning
Medicinal & Uses
Primarily used as an ornamental landscape plant, hedge, or screen due to its vibrant fall color and compact size. The wood is occasionally used for small turned items. No major medicinal applications are widely documented
Ecological Role
Provides cover and nesting sites for small birds and mammals. Flowers attract early-season pollinators like bees. In certain regions outside its native zone, it can exhibit invasive tendencies by self-seeding in natural areas
Similar Species
Three-flower maple (Acer triflorum) and Tatarian maple (Acer tataricum). Amur maple can be distinguished by its distinctly longer middle lobe and glossy leaves compared to the duller, less deeply lobed leaves of the true Tatarian maple
Foraging Tips
Look for multi-stemmed small trees or large shrubs in autumn when their brilliant red foliage stands out in shelterbelts, parks, or old homesteads. Check for opposite leaf arrangement and the characteristically elongated center lobe
Toxicity Warning
Non-toxic. Maples are generally considered safe and non-toxic to humans, cats, dogs, and horses, though fallen decaying leaves in large quantities can occasionally cause digestive upset if ingested by livestock
