description The wild tomato (<i>Solanum sisymbriifolium</i>) is a globally distributed shrubby weed with both negative and positive impacts, including its invasive properties and the potential for pharmaceutical and traditional medicinal uses. Despite its ecological significance, the plant’s reproductive biology and pollination ecology remain poorly understood. This study aimed to investigate the floral biology, pollination ecology, and plant reproduction of the weed species. Some flower traits, such as flowering intensity, flower display size, and pollen and ovule production, peaked during spring, summer, and the monsoon, while flower longevity and stigmatic receptivity were the longest in winter. The plant species was self-compatible (ISI = 0.02), heavily depended on pollinators (IDP = 0.72), and experienced minimal pollination limitation (D = 0.10) under open-pollination conditions. Flower visitors’ traits (e.g., abundance, diversity, and richness) were higher in the spring, summer, and the monsoon, and these were lower in winter. The vital pollination service was provided by <i>Amegilla zonata</i>, <i>Ceratina binghami</i>, <i>Lasioglossum cavernifrons</i>, <i>Nomia</i> (<i>Curvinomia</i>) <i>strigata</i>, <i>Tetragonula pagdeni</i>, <i>Xylocopa aestuans</i>, <i>Xylocopa amethystina</i>, <i>Xylocopa fenestrata</i>, and <i>Xylocopa latipes</i>. Reproductive success, as indicated by fruit and seed set, varied seasonally, being higher during the spring–monsoon period and lower in winter. These findings support effective management of this weed species and help conserve the associated bee populations.
