erraRossa is a red-skinned, red-fleshed
oblong specialty fresh potato variety. It has
also shown promise as a chipping variety, as
chips resist fading and retain their rosy color.
With help from our good friends with the Northwest
Potato Variety Development program, we feature it in
this month's Smorgasbord.
More information, including a list of seed growers of
TerraRossa, can be found at
