Species name: Capsella bursa-pastoris

Shepherd’s-purse are a part of the Brassicaceae (Cruciferae) family. They are easily identified by their heart-shaped seed pods at the top of their stems which are held on by thin stalks. As well as their small white flowers at the top of their stems, and being able to grow up to 40 cm tall.

Their name from their heart-shaped seed pods, as these resemble pouches that were worn by medieval peasants. Capsella in latin refers to ‘little capsule’, and bursa-pastoris refers to ‘Shepherd’s purse’. Along with this, when their seed pods break open, they release copper colour seeds – somewhat like little copper coins!

Shepherd’s-purse are found widespread along the UK, at any time of year in grasslands, farmland, coasts, woodlands, towns and gardens. (The Wildlife Trust)
