Fact Sheets - Potatoes Varieties Ontario potatoes are classified as long, round whites, round reds, or sweet. Long potatoes are the most popular.
Round whites are usually large, round or oval with light to medium skin.
Round reds have rosy red, thin, glossy skins, but otherwise they're similar to round whites. Popular varieties are Chieftain, Rideau, Norland and Sangre. Beauregard, with reddish skin, and the smaller copper-toned Jewel are the major sweet varieties grown in Ontario. Buying and Storing Look for firm, dry, well-formed potatoes, free from bruises, dark spots, cuts, cracks and sprouted eyes. Avoid potatoes greened by in-store florescent lights.
