Kingcups, one of the brightest bog and waterside flowers, are also known as Marsh Marigolds, Water Blobs, ‘Oss Blebs, Water Bubbles and Meadowbright. These plants are wild and ancient, possibly pre-dating the last ice. They erupt into bloom in Spring and to the human eye they bring a welcome flurry of golden-yellow flowers above glossy green leaves. Each flower has a hidden UV pattern guiding insects to a rich source of nectar whilst also facilitating pollination. Fresh from hibernation this Tortoiseshell butterfly was drifting from cup to cup sipping nectar along the way. In May Kingcups used to be strewn around the doorways of houses (and perhaps over thatched roofs) to bring good luck.
