Bring a touch of the rugged beauty of the Rocky Mountains to your own backyard with Acer grandidentatum, also known as Bigtooth Maple. This small to medium-sized deciduous tree offers an impressive trunk diameter of 20-35 cm and can grow up to 15 m tall. Its unique bark features plate-like scales that create narrow fissures and flat ridges, and its leaves are simple yet eye-catching, with three to five deep lobes and a golden yellow to red color in fall.
In mid-spring, Acer grandidentatum blooms in clusters of 5-15 flowers, each about 4-5 mm in diameter and yellow-green in color. The fruit of this tree is a paired samara, green to reddish-pink in color and maturing brown in early fall.
This tree is adaptable to a wide range of well-drained soils, including sand, clay, and even white limestone areas. It is commonly found in valleys, canyons, and on the banks of mountain streams, primarily at higher elevations. However, it is also capable of thriving in maritime climates, making it an excellent choice for a variety of landscapes.
While it is slow-growing when young, Acer grandidentatum is highly valued for its drought tolerance and ability to grow in rocky landscapes. It is occasionally planted as an ornamental tree, and its unique characteristics and resilience make it an excellent addition to any landscape.
This tree goes by many names, including Canyon Maple, Limerock Maple, Lost Maple, Plateau Big Tooth Maple, Rocky Mountain Sugar Maple, Sabinal Maple, Southwestern Big Tooth Maple, Uvalde Big Tooth Maple, Wasatch Maple, and Western Sugar Maple. No matter what you choose to call it, Acer grandidentatum is a breathtaking and hardy tree that will add style and character to any outdoor space.
