Damselfly on Caltha palustris
Highdown Gardens near Worthing, West Sussex ...
Caltha palustris, known as Marsh Marigold and Kingcup, is a perennial herbaceous plant of the family Ranunculaceae, native to marshes, fens, ditches and wet woodland in temperate regions of the Northern Hemisphere.
It becomes most luxuriant in partial shade. It is rare on peat. In the United Kingdom, it is probably one of the most ancient native plants, surviving the glaciations and flourishing after the last retreat of the ice, in a landscape inundated with glacial melt waters.
The flowers are yellow, with 4-9 (mostly 5) petal-like sepals and many yellow stamens. They appear in early spring to late summer. The flowers are visited by a great variety of insects for pollen and for the nectar secreted from small depressions, one on each side of each carpel. Hoverflies, bees, butterflies and dragonflies love the flowers.
Carpels form into green sac-like follicles to 1 cm long, each opening to release several seeds.
Caltha palustris is a highly polymorphic species, showing continuous and independent variation in many features. Forms in the UK may be divided into two subspecies: Caltha palustris subsp. palustris, and Caltha palustris subsp. minor.
It is sometimes considered a weed in clay-like garden soils, where every piece of its root will survive and spread. In warm free-draining soils, it simply dies away. It grows well as a pond marginal, or in the water with up to 4" of water above the basket.
As is the case with many members of the family Ranunculaceae, all parts of the plant are poisonous and can be irritant. Skin rashes and dermatitis have been reported from excessive handling of the plant. It is known to sometimes kill cows and will happily grow in cow manure.
