About 2 million acres of canola are grown annually in the United States, primarily in the Northern Plains, Pacific Northwest and Southern Great Plains. In 2021, nearly 2.2 million acres of canola were planted in 29 states, led by North Dakota (79%) and followed by Montana (7.7%), Washington (5.4%), Idaho (3.6%), Minnesota (2.8%) and Oklahoma (0.5%).
There are two types of canola: spring and winter, named as such for when they are planted. Spring canola is planted in early spring (March) and harvested around September. This type accounts for the majority of U.S. canola production. Winter canola planted in the fall (September) over winters and is harvested in June. Typically, winter canola will yield 20 to 30 percent more than spring canola. It is grown in warmer areas like the Southern Great Plains. In the Pacific Northwest, both spring and winter types of canola are grown. In the Northern Plains, spring canola is typically grown while in the Southern Plains, the winter type dominates.
