What’s Blooming in September?

The chart represents the approximate bloom times in Minnesota. Factors such as temperature and precipitation play a large role in how a plant fares year after year. Northern MN should also start a bit later and/or end a bit earlier than Southern MN.

Only native plants are listed here. If you are looking for something specific, try the “find in page” feature of your browser (usually CTRL+F).
