First Flowering Dates and Flowering Periods of Prairie Plants at Woodworth, North Dakota

J. Michael Callow, Harold A. Kantrud, and Kenneth F. Higgins

Abstract: We recorded flowering events for 97 species of prairie plants for 2-6 years near Woodworth, ND. Earliest and latest flower initiation dates varied by year. Temperature seemed much more important than precipitation in influencing phenology of species that bloom from late March through May, but no strong climatic effect was evident for plants that bloom later in the growing season.

Key words: Phenology, plants, North Dakota, temperature, precipitation
