Fall Grandeur™ Red Maple - Acer rubrum 'Minkota' (RFM-70)
Red Maple is an eastern North American maple species, native as far west as Minnesota and Oklahoma. Since it prefers slightly acid, moist soils, many introduced cultivars in the commercial nursery trade are poorly adapted in the Northern Great Plains. Furthermore, many cultivars are deficient in winter hardiness in USDA hardiness zones 3-4, often suffering severe trunk sunscald injury. Fall Grandeur™ originated as a seedling from a Minnesota seed source, and has performed exceptionally well in NDSU arboretum evaluations for over 30 years. It has good foliage qualities, typically with three major leaf lobes. Fall color is a showy red. Tree form is upright, and densely ovate-elliptical. Currently, this select cultivar is 31' tall and 14' in width, and has averaged 1' of growth per year growing in sod. There has been no evidence of iron chlorosis in moderately alkaline pH soils. Due to its aesthetic qualities and superior adaptation in the Northern Plains, Fall Grandeur™ needs to be propagated by wholesale nurseries and made available for planting over a more extensive area of the Northern Plains and upper Midwest. Softwood cutting propagation recommended. Shade, park and specimen tree. USDA hardiness zone 3.
