Description
- Title:
- Marsh Marigold (Caltha palustris) Multispectral
- Caption / Description:
-
Multispectral (Ultraviolet, Visible, and Infrared) photo of Marsh Marigold flowers in Spring. The flowers appear plain yellow to the human eye, which cannot see ultraviolet or infrared light.
Under ultraviolet light a clear 'hidden' pattern can be seen, with the centre of the flower being dark while the edges of the petals are bright.
Foliage generally reflects a high amount of infrared light, which can be seen in this image by the bright red colour of the plant's leaves in the background.
Caltha palustris (kingcup, marsh marigold) 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, but 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 meltwaters.
