The pollination system of a naturalized native perennial- Penstemon cobaea.

Reproductive ecology of a flowering species can vary over time. This study focuses on shifts in the reproductive ecology of a glade population of Penstemon cobaea over a 20-year span. We collected morphological and current pollination data and compared it with earlier data sets. We tested for pollen limitation. This study found the main pollinator hasn’t remained consistent over 20 years and P. cobaea is not currently pollen limited. The in-stability of the pollination system could be due to various abiotic factors such as a colder winter, or an early high heat index in 2018.
