The bulbous buttercup is a perennial herb that gets its name from its distinctive 'perennating organ': a bulb-like, swollen underground stem, which is situated just below the soil's surface.It becomes established where fresh soil is exposed, finding it hard to compete with taller, established plants. It prefers nutrient-poor, well-drained soils, and can be found on sunny, chalk and limestone grasslands, in particular. As its name suggests, it has familiar butter-yellow flowers that appear from March to May
