A pyrimad-shaped deciduous tree that does not get too wide, it hails from Japan, Korea and China's Manchuria. Its barks becomes light gray-sandy brown with shallow fissures. In early spring this tree flowers. The male flowers are in drooping, finger-like clusters called catkins and are yellow-brown. The female flower are small and purplish and occur along the twigs on very short stems. After wind pollination, the green cylindrical fruits form and ripen to a sienna brown before shedding the winged seeds. The dried fruits persist on the branches into fall and winter. The leaves are glossy dark green, tapered ovals with minute irregular teeth. No notable fall leaf coloration occurs. Grow Japanese alder in average garden soils that are moist to wet, or average well-draining. It is adaptable to acidic and alkaline soils regardless of fertility. It will tolerate drier conditions and occasional flooding! It is best in regions with cool summers, and in the warmest parts (zones 7 and 8) it may only grow as if a large shrub. This species is fast growing and also works well as a windbreak in addition to being a specimen shade tree for park or avenue. Use it to vegetate the water's edge or in drier infertile soils where little else will cast shade. Bonsai suitable. Information source: www.learn2grow.com. Extra seeds The seeds are hand-selected.
