摘要

Beyond aesthetic appeal, gardening is an emerging strategy for addressing the challenges posed by pollinator decline, climate change, and habitat loss. This study aimed to evaluate species-level insect visitation patterns among 21 native and cultivated ornamentals and to examine how plant origin, floral traits, and flowering duration influence pollinator visitation. Twenty-one species (10 native, 11 cultivated) were planted within a 108 m² experimental plot divided into three distinct zones of A (native), B (native and cultivated mixture), and C (cultivated), with seven replications, and insect visitation was monitored 27 times from July to October 2024. Insects were collected and identified by functional groups, and biodiversity was assessed using species richness (R) and Shannon-Weiner index (H’). Balanced flower colors of purple, pink, and white, and diverse inflorescence types both in native and cultivar ornamentals attracted five ranges of insect visitors by aligning with their visual and foraging preferences. The extended flowering periods of the cultivated ornamentals complement the seasonal peaks of the native ornamentals, ensuring continuous nectar and pollen availability from May to November. Insect visitation varied across insect trophic groups and plant types, with pollinators being the most frequent among those insects and the highest overall insect visitation to Zone C, but pollinator visits were similar between Zones A and C, suggesting that native and cultivated ornamentals both play essential roles in supporting pollinator communities. With purple flowers attracting the most pollinators overall, followed by pink and white, native plants generally supported greater pollinator richness and diversity than their cultivated counterparts, though some cultivated species performed better in attracting pollinators. These findings highlight species-specific patterns in pollinator attraction and underscore the complementary roles that both native and select cultivated ornamentals may play in supporting pollinator biodiversity.
