The Marmo maple is one of the first hybrid crosses made between the silver maple and red maple. This strong-growing shade tree combines the brilliant red (and some yellow) fall color of the red maple with the toughness of the silver maple. The 5-lobed leaves are intermediate in shape between the two species. It has a nice upright oval shape and is seedless.

This tree is a Chicagoland Grows® selection. Chicagoland Grows is a plant introduction partnership of the Chicago Botanic Garden, the Morton Arboretum and the Ornamental Growers Association of Northern Illinois formed to promote plant cultivars that perform well in northern Illinois. This variety was developed at the Morton Arboretum; it is named in honor of Margaret Morton.
