The first pond flower of the season has opened up in my garden. One of my favourite water plants, the Marsh Marigold (Caltha palustris), which I planted last year, shows off a bright yellow bloom. Hopefully a good nectar source for insects. My pond is only small, as can be seen in the image below, but I am amazed how much wildlife it has attracted. It will be 1 year old at the end of April.
