Lesser celandine (Ranunculus ficaria, syn. Ficaria grandiflora Robert, Ficaria verna Huds.) is a low-growing, hairless perennial flowering plant in the buttercup family Ranunculaceae. It has fleshy dark green, heart-shaped leaves and distinctive flowers with bright yellow, glossy petals. The plant is found throughout Europe and west Asia and is now introduced in North America, where it is often considered invasive. It prefers bare, damp ground and in the UK it can be seen as a common garden plant, an early harbinger of Spring.
Ranunculus ficaria exists in both diploid (2n=16) and tetraploid (2n=32) forms which are very similar in appearance. However, the tetraploid type prefer more shady locations and frequently develops bulbils at the base of the stalk. These two variants are sometimes referred to as distinct sub-species, R. ficaria ficaria and R. ficaria bulbilifer respectively.
According to Gilbert White, a diarist writing around 1789 in the Hampshire village of Selborne, the plants came out on February 21, but it is more commonly reported[vague] to flower from March until May[clarification needed], and is sometimes called the "spring messenger" as a consequence.
In non-native locations
In many parts of the northern United States and Canada, lesser celandine is cited as an invasive species. It poses a threat to native wildflowers, especially those ephemeral flowers with a spring-flowering lifecycle. It is mainly a problem in floodplain forests, where it forms extensive mats, but it also can occur on upland sites as well.
In North America, the US National Park Service's Plant Conservation Alliance recommends avoiding planting lesser celandine, and instead planting native ephemeral wildflowers such as Asarum canadense, bloodroot, the native twinleaf (Jeffersonia diphylla), and various species of trillium as alternatives.

The plant used to be known as Pilewort because it was used to treat hemorrhoids. Supposedly, the knobbly tubers of the plant resemble piles, and according to the doctrine of signatures this resemblance suggests that pilewort could be used to cure piles. The German vernacular Skorbutkraut ("Scurvyherb") derives from the use of the early leaves, which are high in vitamin C, to prevent scurvy. The plant is widely used in Russia and is sold in most pharmacies as a dried herb.
Medicines should be made from the dried herb or by heat extraction as the plant contains protoanemonin, a mild toxin. A single case was reported with acute hepatitis occurring after consuming a remedy made from lesser celandine.  However, the process of heating or drying turns the toxin to anemonin which is non-toxic and has antispasmodic and analgesic properties.[medical citation needed]
References in literature
The poet William Wordsworth was very fond of the flower and it inspired him to write three poems including the following from his ode to the celandine:
- I have seen thee, high and low,
- Thirty years or more, and yet
- T'was a face I did not know.
Upon Wordsworth's death it was proposed that a celandine be carved on his memorial plaque inside St Oswald's Church, Grasmere, but unfortunately the greater celandine Chelidonium majus was mistakenly used.
C. S. Lewis mentions celandines in a key passage of The Lion, the Witch and the Wardrobe, when Aslan comes to Narnia and the whole wood passes "in a few hours or so from January to May". The children notice "wonderful things happening. Coming suddenly round a corner into a glade of silver birch trees Edmund saw the ground covered in all directions with little yellow flowers - celandines".
"...going down the hedgeside with the girl, he noticed the celandines, scalloped splashes of gold, on the side of the ditch. 'I like them' he said 'when their petals go flat back with the sunshine. They seem to be pressing themselves at the sun.'
And then the celandines ever after drew her with a little spell."
