This delicate little flower, pink evening primrose, is also known as buttercup or pink buttercup and blooms from April to June. The flowers wither at the end of each day and are replaced by new blossoms in the evening. The bees like these flowers, and when they go to seed, birds will visit them–especially finches.
The greens can be eaten in salads or cooked, but the flavor is better if harvested before the flowers bloom. It seems a shame to miss the opportunity of seeing these sweet flowers on a beautiful spring day, though.
