The Marsh marigold or Kingcup, Caltha palustris, is a British native, producing large buttercup flowers in spring. It is ideal for a bog garden or he edge of a pool. There are related species from elsewhere, some with yellow and some with white flowers.
Caltha leptosepala subsp. biflora NNS07-87 has large, roundish, wavy-edged leaves, and white flowers on tall stems. It is a beautiful plant for a wet place, naturally coming into growth as the snow melts.These plants derive from a population in the eastern Cascade range. The subspecies is sometimes known as a species, Caltha biflora. Biflora means that it has two flowers per stem - sometimes!
