Ivy-like Merremia (Merremia hederacea, 篱栏网).
Near the river, there are often a few unostentatious pink, yellow or white flowers from various bindweeds. But in one great Michaelmas show, the velvety green vines of ivy-like merremia flowered in abundance, and with it life has changed: bluebottle butterflies, asian honey-bees and hosts of other insects have come for the pollen, multifarious spiders have come to ensnare pollinators, and songbirds have come to feast off the spiders. Out of nowhere these small buttery flowers are everywhere.
