Abstract Phenology reveals strategies related to resource utilization and ecosystem dynamics, providing essential information for species management and conservation. However, global climate change can trigger significant alterations in phenological behavior, especially in species that are highly dependent on seasonality. In this context, this study aimed to evaluate the reproductive and vegetative phenology of Richeria grandis Vahl, a dioecious species with a wide geographical distribution and unique environmental specificity, under the premise that this species is highly dependent on local and regional climate for its growth and reproduction. Monthly phenological monitoring of the selected populations was conducted over 24 months, and the intensity of each phenophase was assessed using the Fourier index. Circular statistical analyses were employed to determine the degree of synchrony and significance of seasonality in phenophases. Richeria grandis flowers for a period of 5–6 months annually and regularly. It is synchronized between sexes and has high seasonality. Overall, the fruiting phenophase displayed a behavior similar to that of flowering, with peaks of intensity occurring in short time intervals and with high seasonality. Fruit production is characterized by variations between years with high and low yields and is termed supra‐annual production. The vegetative habit of Richeria grandis is evergreen, with annual foliage renewal, and the results of the circular analysis indicated low seasonality for all vegetative events.
