Assessment of Floristic Composition of Ornamental Plants and Their Production Conditions in Benin (West Africa): Highlights Ornamentals' Role to Bolster Ecological Conservation and Urban Greening

Characterization of Ornamental Plants

Abstract

This study characterizes ornamental plant sites in Benin, acknowledging horticultural role in Urban Greenery. Surveying 136 sites revealed 175 species from 139 genera and 56 families. Dominant families like Asparagaceae, Euphorbiaceae, Apocynaceae and Araceae showcased rich botanical diversity. Key species, including Gerbera garvinea and Delonix regia were noted. Analyses highlighted prevalent nano-phanerophyte and micro-phanerophyte life forms, indicating a preference for perennial plants. Chorological analysis emphasized pantropical and Afro-malagasy species dominance. Numeric classification revealed three site groups based on richness, age and area. These groups showcased species' richness ranging from 112 to 141. Diversity measures emphasized substantial ornamental diversity. These sites significantly contribute to biodiversity, necessitating strategic valorization plans. This study provides groundwork for economic potential exploration and ethnobotanical insights in ornamental plant production, which is essential for conservation and urban development.
