Double Bird's Foot Trefoil

Lotus corniculatus is a common flowering plant native to grassland temperate Eurasia and North Africa. The common name is Bird's-foot Trefoil (or similar, such as "birdsfoot trefoil"), though the common name is often also applied to other members of the genus. It is also known in cultivation in North America as Birdfoot Deervetch.
A double flowered variety is grown as an ornamental plant. The plant is an important nectar source for many insects and is also used as a larval food plant by many species of Lepidoptera such as Six-spot Burnet. It is regularly included as a component of wildflower mixes in Europe. Fresh birdsfoot trefoil contains cyanogenic glycosides and is thus poisonous to humans.
The plant is one of the few flowers in the language of flowers that has a negative connotation, symbolizing revenge or retribution.
