Native or Not Present

This map is based on our research. We have checked its accuracy to Level 3 ecoregions. Although this plant occurs somewhere in each of these regions, it may only occur in a small part of some or all of them.


As Q. montana is more of a specialist on drier sites with thin, rocky or sandy, acidic soils, and Q. alba is more of a generalist that is not as tolerant of dry, nutrient-poor conditions, this species is most likely to be found in intermediate conditions, soils that are still relatively thin, sandy or rocky, and dry, but richer in organic matter and nutrients than the sites preferred by Q. montana.

Life Cycle

This hybrid has unusually large and consistent acorn production.


This hybrid is occasionally sold in nurseries and used in landscaping. It is valued for its rapid growth, drought tolerance, and high acorn production for those who desire to support wildlife.
