These are floury potatoes with good flavour.
The plant gives high yields in a late harvest.
They were marketed as being good both for sale direct to consumers, and for processing into potato chips (aka crisps in the UK.)
They are no longer in commercial production. They are now mostly just grown by home gardeners.
Denali Potatoes were developed by the United States Department of Agriculture (USDA) and the University of Alaska at the Agricultural Experiment Station in Palmer, Alaska from a cross between Lenape potatoes and a potato referred to as “AK1-62-90-64” in 1968.
During development, the potato was referred to as “AK37-68-19-70.”
