Cardiocrinum cordatum var. glehnii (Liliaceae) is a monocarpic perennial herb living in temperate broad‐leaved deciduous forests. In the present study we examined the sizes (basal diameter of the stem and flower numbers) of flowering individuals and genetic diversity using microsatellite loci of 23 populations of C. cordatum var. glehnii in Hokkaido, Japan, over 2 years (2009 and 2010). As a result, we found both the basal stem diameter and the number of flowers varied widely among the populations. However, although the sizes of flowering individuals differed among the populations, these were very stable in each population and in each year. In addition, for genetic diversity, the same trends (i.e. wide variation among the populations but non‐annual variation) were detected.
