Data were collected to determine the geographic distribution of different cytotypes of Campanula rotundifolia L. Most sampling concentrated on Britain and Ireland, but samples from mainland Europe, the Russian Federation and North America were also analysed. Following these observations, a common garden study of tetraploid, pentaploid and hexaploid cytotypes representative of Britain and Ireland was set up at a CEH Edinburgh (where the local cytotype is tetraploid), to determine whether climatic factors were limiting the distribution of the hexaploid cytotype through effects on growth, survival or flowering phenology.
The geographic distribution study ran from 2006-2019. The common garden study ran from 2008-2010.

Provenance & quality
For Britain and Ireland, field collection were guided by use of Botanical Society of Britain and Ireland distribution maps and an understanding of habitat preferences. Cytotypes were determined by flow cytometry and supported by chromosome counts. Data were partitioned into diploid, tetraploid, pentaploid and hexaploid, and intermediate aneuploids. All samples were run with internal reference standards, and analyses were re-run or discarded if the cv > 5%. In the common garden study shoot dry weights and numbers of flowers, flower buds, seed heads and flowering stems were determined. Flowering phenology was assessed by observation of first flowering date, when the first flower was sufficiently open to be entered by bees.
