Buttercups are a large genus of flowering plants called Ranunculus. It has yellow, shiny petals, and grows wild in many places. It is poisonous to eat for humans and cattle, but when dry the poison is not active.
Types of buttercup
There are about 200 to 600 species in this one genus. They mostly have yellow or sometimes white flowers. Buttercups include a wide variety of flower types, grouped by a plant naming system in the genus Ranunculus. Among them are the Meadow Buttercup (Ranunculus acris), Goldilocks Buttercup (R. auricomus), Creeping Buttercup (R. repens), Large White Buttercup (R. platanafolius), Celery-leaved Buttercup (R. sceleratus), Corn Buttercup (R. arvensis), Bulbous Buttercup (R. bulbosus) and Glacial Buttercup (R. glacialis).
Lesser Celandine (R. ficaria), Lesser Spearwort (R. flammula), and Greater Spearwort (R. lingua) also belong to the buttercup family.
Plants of the commonly named buttercup family grow in many different variations but most can be identified by their yellow cupped flowers and free-growing habit. The plants often climb or sprawl, with leaves arranged in spirals. Some may contain leaves without stipules and flowers with many stamens.
Molecular investigation of the genus shows that Ranunculus is not monophyletic. Proposals are under way to split up the genus.
Folklore and Pop Culture
Highlights shining on the reflective petals of the buttercup can be seen in the images at left and above.
People sometimes hold a fresh buttercup flower under the chin of a friend or family member. If a yellow reflection from the flower's shiny petals can be seen under the chin, the person is said to "like butter". This custom is still taught to young children and shows how buttercup petals reflect light.
Some other plants and people are named buttercup, based on the name of the yellow wild flower. These include a type of pumpkin, and the girl's name Buttercup.
"Build Me Up Buttercup" was the name of a popular song by The Foundations during the 1960s. A song called "Buttercup" was released by Jack Stauber in 2017. A cartoon character from the Powerpuff Girls television series was also named Buttercup. Buttercups and their poisonous effect are used as a theme in the PC game Undertale.
