Eugenia uniflora is an exotic fruit species with significant health benefits and considerable ornamental potential. Although substantial research has been conducted on E. uniflora germination, there remains a need for further study on this species’ generative propagation to address unexplored aspects of its reproductive processes. Thus, this study aims to describe E. uniflora germination and seedling biology and the impact of tree and ground fruit seeds on the germination and seedling parameters of the plant species from the Indonesian population. This study employs a completely randomised design of three replications for its germination and seedling parameters trial. Germination parameters, including final germination percentage (FGP), time for 10% (T10), 50% (T50), and 90% (T90) seed germination, and infected seed percentage, were calculated along with seedling parameters such as mean shoot length (MSL), mean root length (MRL), mean total length (MTL), vigour index, and growth index. Quantitative analysis followed by student’s statistical analysis was conducted for these parameters. Descriptive analysis was also performed to study the E. uniflora germination process, germination type, and seedling functional type. This study shows that E. uniflora has hypogeal germination. Cryptocotylar, hypogeal, and reserve storage seedling functional types were observed. Seed harvested from tree and ground fruit does not exhibit significant differences in all germination and seedling parameters. However, this study found that seed infection was also present in ground fruit seeds. The results of this study fill knowledge gaps that support the sustainable use of E. uniflora.
