Alnus maximowiczii

Click for larger image

Alnus maximowiczii is grown for it’s very showy display of big, fat green/yellow catkins in spring. Handsomely doubletoothed large leaves that provide heavy shade. More of a tree than most of the green alders. Sometimes multistemmed.

The showy catkins give it a real WOW factor. Rapid growth means it will soon establish in the garden.
