Bigleaf Maple (Acer Macrophyllum) 30 seeds

This immense deciduous tree bears the largest leaves of all maple species and is spectacular when it turns golden in the fall. It is counted among the few true western native maples, its range extending from foothills of Alaska to southern California and eastward to the Sierra Nevada Mountains. It is nearly always found in conjunction with streams and creeks. In warmer regions it grows at the base of north-facing slopes where perpetual shade and summer dampness support its need for moisture during the growing season.
The big leaves can be truly enormous and are borne heavily on upright stems. Trees produce inconspicuous wind-pollinated flowers in the early spring, which mature into winged seeds called samaras. The new leaves are bright yellow green and darken through summer. The change to gold begins with the cooling of late summer nights.
Grow this tree in sites with good moisture and partial sun. It is a good choice for expansive rural home sites with high water tables and perennially wet conditions in the west. Big-leaf maple creates habitat for wildlife, has high ornamental value and easily naturalizes. Further north its bark becomes home to mosses and ferns. This tree contains very sweet sap that can be distilled to create syrup that equals that of sugar maple. (info source: Learn2Grow.com)
