Infrared photo of a flowering Ranunculus bulbosus (Bulbous buttercup) plant growing in grass along an abandoned railway line. In infrared the stem and leaves of the plant (and the surrounding grass) are as bright as the flowers. This is because chlorophyll strongly reflects near-infrared light, making the green parts of plants appear bright in infrared.
Ranunculus bulbosus is so named because it has a corm that helps the plant survive over winter. Without digging the plant up to see the corm, it is still identifiable by the way the sepals behind the flower fold back on themselves.
The plant blooms from April to May, bearing yellow flowers around 1.5 - 3 cm wide.
