Plant reproduction is highly dependent upon phenology, or biological timing, of flowering. However, little is known about how individuals vary in their flowering schedules relative to the population as a whole or how this variation could lead to differences in reproductive success of individuals. Here, it was shown that individuals of Hydrophyllum fendleri (Boraginaceae) were aggregated in time and that individuals that flowered later had a higher reproductive success than those that flowered earlier in the season. I tested the hypothesis that pollen limitation was responsible for the temporal variation in reproduction observed. Although it was shown that plants were indeed limited in fruit and seed production by pollen receipt, pollen limitation was consistent across the growing season, suggesting that other factors caused the variation in reproduction.
