[Note Guidelines] Photographer's Note
Caltha palustris commonly known as Kingcup or Marsh Marigold (also known as Calthus palustris syn. Trollius paluster Krause) is a member of the family Ranunculaceae, and is native to temperate regions of the Northern Hemisphere, growing in wet, boggy places.

It is a herbaceous perennial plant growing to 80 cm tall. The leaves are rounded to kidney-shaped, 3-20 cm across, with a bluntly serrated margin and a thick, waxy texture. The flowers are yellow, 2-5 cm diameter, with 4-9 (mostly 5) petaloid sepals; they are borne in early spring to late summer. Stems are hollow.

It is sometimes considered a weed in clayey garden soils, where every piece of its root will survive and spread. In warm free-draining soils, it simply dies away.

The whole plant, but especially the older portions, contains the toxic glycoside protoanemonin - this is destroyed by heat. The sap can irritate sensitive skin.

Edible Parts: Flowers; Leaves; Root.

Root - must be well cooked. The raw root should not be eaten. Some caution is advised, see the notes above on toxicity. Flower buds - raw, cooked or pickled and used as a caper substitute. Eating the raw flower buds can lead to intoxication. Young leaves - raw or cooked. The leaves are harvested in the spring as the plant is coming into flower and is used like spinach after cooking in two or more changes of water. Eating the raw leaves can lead to intoxication. Some caution is advised, see the notes above on toxicity. Older leaves, before the plant flowers, can be eaten if they are well cooked.

Every part of this plant is strongly irritant and so it should be used with caution. The whole plant is anodyne, antispasmodic, diaphoretic, diuretic, expectorant and rubefacient. It has been used to remove warts and is also used in the treatment of fits and anaemia. The root is antirheumatic, diaphoretic, emetic and expectorant. A decoction is used in the treatment of colds. A poultice of the boiled and mashed roots has been applied to sores. A tea made from the leaves is diuretic and laxative. All parts of the plant can irritate or blister the skin or mucous membranes.

From wikipedia and pfaf.org-this site is really great showing info on lots of plants and their uses in medication and food.

Thanks for stopping by!!

Hello Catalin,
Aside from the beauty of the kingcup, your photo shows incredible contrast of that vibrant yellow against the dark background. Very catchy and pleasing to the eye. Well done. Regards,

Salut Catalin,

Foarte frumoase culori si detalii!

Very nice macro shot, great colours and good lighting.

Simpatica compozitie, si frumos efect intre galgenul luminos al florilor si fundalul cu nuante de verde intunecat. Si detaliile sunt OK. Ce raspandita poate fi si aceasta specie, nu-ti vine sa crezi. Felicitari.

Hi Catalin, lovely views of this very interesting flower. It is nice to see 2 views, i think I may try it. You have caught the light very well on these and they are very sharp in detail with great depth of colour. You notes are fantastic.

Preciosos colores y magníficos los detalles de esta composición.
Hermosas flores.
