The first showy spring flower was Lesser Celandine. (Shot April 20.) There is an occasional brook at Centennial Park in Wellesley, MA, that is enough moisture in this bit of dry valley that a big field of yellow erupts there in spring.
The blossoms follow the sun during the day and close in cloudy or cold weather. The name Celandine is derived from the Greek word for swallow (chelidon), because the early flowering time was also when the swallows arrived (and the flowers faded when they left). It is not native, found throughout Europe and west Asia. Eight petals and leaves that resemble wild ginger. Don’t eat it: “Unsafe in any quantity.” Buttercup family.
