![Boechera stricta is a type of mustard that reproduces predominantly from self-
fertilization (~95% of individuals). Scientists surveyed for variation in flower color as a
function of the environment. Most have white flowers (a,b in photo below) while some
plants have pink or purple flowers (c-f). Researchers found that having pigmented
flowers was highly heritable. They found that pigmented flowers had lower fecundity
when well-watered, but pigmented flowers had lower rates of herbivory than white
flowers. They hypothesize that the lower herbivory is because the same types of
compounds responsible for floral pigmentation are also distasteful to herbivores.

The researchers can eliminate the possibility of pollinator selection as a contributing factor to flower color variation in Boechera stricta due to the species' predominant mode of reproduction, which is self-fertilization. Approximately 95% of Boechera stricta individuals have the capacity to reproduce without relying on cross-pollination. Consequently, the color of the flowers, which conventionally serves to attract pollinators, does not significantly influence the reproduction of this plant species.
