Biotic homogenization is a global phenomenon, mainly in urban areas where exotic species are dominant, contributing to the loss of native biodiversity. Gardening native flora to promote local biodiversity is becoming a conservation practice in urban settings. Therefore, in this study, we analyzed the representation of the Chilean native flora in the Chilean and international ornamental flower seed market to know which native plant seeds are sold. We found that native seed are absent in the local market and that the totality of seed supply in the market corresponds to species of exotic origin, mainly from the Palearctic region (43%). However, surprisingly, many Chilean flower seeds are traded in the international market (approximately 6% of the total Chilean flora). This lack of availability of native seeds for local consumers constitutes a bottleneck for ecological restoration initiatives. It is consistent with the greater abundance of exotic species in urban green areas and supports the hypothesis of biocultural homogenization.
