Mean flowering stage at specific transect positions across the mine boundary in 1965, in common garden conditions in 1966 (McNeilly and Antonovics, 1968; Antonovics and Bradshaw, 1970), and in the field in 1979 and 2005. Values are standardized as deviations from the overall mean flowering stage within each year. Negative distances on the X-axis represent metal contaminated soil and positive values represent pasture, with zero being at the mine-pasture boundary represented by the vertical dashed line.
