Do bees like bougainvillea or would it be a waste to plant it over an arbour? Also if they like it does it create a good honey?
The flower?s trumpet shape and long throat are designed for specific pollinators; namely butterflies, moths and hummingbirds. A long tongue (or proboscis in the case of butterflies or moths) is needed to access the nectar stored near the flower?s base, so bees and wasps aren?t typically interested in bougainvillea.
