Marsh Marigold flowering stoically in the pond. The more this area of the garden develops (now in its 6th year since filling and planting up) the more I’m drawn to it. Garden ponds, no matter what the size or scale, are forever an eye witness source of evolution. You begin with a few periphery plants and before you know it you have all kinds of aquatic growth appearing from water mint and iris to frogs and damselflies. Marsh marigold however (Caltha palustris) is the true beacon in the bog, so to speak. It’s one of our oldest native wildflowers in fact, having pushed its little yellow light bulbs up through the thawing ice-age.
