Buttercups belong to the Ranunculus genus, with one of the most widespread species being the creeping buttercup, Ranunculuc repens. True to it’s name, this species can spread through long runner stems which can put down roots. The root ball can be deeply anchored, making it difficult to remove. The petals have a high gloss, which allows them to reflect light – as in the children’s game of holding a flower under your chin, with a yellow reflection indicating that you like butter. Buttercups are poisonous to many livestock, though the toxins degrade in dried hay. In traditional medicine, buttercups are used to treat fever and rheumatism, though the sap can cause skin blistering.
