Ragged robin (see picture) is fairly common along roadsides and wet fields. Its latin name Lychnis flos-cuculi, as well as many of its foreign names, makes a reference to the cuckoo bird. Some people say that the flower blossoms when the first cuckoo is heard. But that's not necessarily the case. The name really refers to the froth often found on the plant. It was believed to be spit from the cuckoo. However, the froth is made by the meadow spittlebug during its nymph stage. The red and white campions and the ragged robin are common wild flowers, which sometimes cross-pollinate.
