Shepherds Purse
Broadleaf annual weed
Shepherds purse is a brisk annual weed often noticed when its distinctive seed pods rise above a basal rosette. It is adaptable, setting seed quickly in vegetable beds, paths and container edges. Its long flowering season means small plants should be cleared before they form their recognisable heart-shaped pods.
How to identify it
Young plants make a rosette of toothed or lobed leaves close to the soil, though leaf shape can vary. Slender, branching flower stems then reach 10 to 50 cm tall. Tiny white flowers have four petals and are followed by flat, triangular to heart-shaped seed pods, each about 5 to 8 mm long. Leaves on the upper stem are narrow and clasping. It has a modest taproot with fine side roots, allowing young plants to be pulled from moist ground.
Where it grows
This weed grows throughout the UK in cultivated borders, vegetable plots, paths, paving cracks and pots. It germinates mainly in spring and autumn, but can grow through mild winters and flower for many months. It favours open, disturbed soil and often appears after digging, sowing or clearing an older crop.
Why it is a problem
Its prolific seed production allows it to reappear after every soil disturbance. Seedlings compete with slow-germinating vegetables and young ornamental plants, while mature stems can shed seed into paths, beds and containers. Because flowering and seed pods may occur together, delaying removal even briefly can allow the next generation to begin.
How to control it
Hoe small seedlings on a dry day, before flowers or pods develop, and allow them to dry on the soil surface. Hand-weed plants among crops, easing out the taproot with a hand fork if the soil is firm. Remove flowering plants carefully and do not leave ripe pods in the bed. Mulch established borders and vegetable rows to reduce light at the soil surface. Cover empty areas and make regular quick checks after cultivation or rain.
Commonly confused with
The rosette can resemble other mustard-family weeds, including hairy bittercress and hedge mustard. Shepherds purse is best recognised once its flat, heart-shaped pods appear. Its small white flowers also separate it from dandelion-like rosettes, which later produce yellow flower heads.
