Sherburne County Minnesota
Few, if any, garden perennials bloom all season long. In some cases bloom ends after five or ten days.
Some of the longest blooming perennials are listed in the following table. However, most plants said to bloom from June till September have a peak bloom time followed later by scattered blooms only when conditions are favorable.
