Prairie Torch® Hybrid Buckeye - Aesculus x 'Bergeson'

A very winterhardy hybrid buckeye selected in northwestern Minnesota. Introduced by North Dakota State University in collaboration with Bergeson Nursery, Fertile, MN.  In NDSU trials, it grew faster than most buckeye accessions for the first 10 - 15 years, producing a rather dense, globose form. With age it broadens, becoming more mushroom-shaped. Ultimate size of tree is small-medium, 20 to 28', which fits well in residential landscape sites. The foliage is of high quality, fairly coarse-textured, and typically composed of 7 leaflets, which incline downward in an umbrella-like fashion. These characteristics lend a tropical touch to the tree's appearance. Autumn coloration in medium to light-textured soils, is brilliant orange-red. This cultivar is far superior in quality to most seedlings of Ohio Buckeye - Aesculus glabra.  Limited availability in nursery trade. USDA hardiness zone 3. Small shade and landscape specimen tree. Propagated by grafting, possible by budding and softwood cuttings.
