Charlock Mustard is a non-native annual plant of the UK, typically found growing in cropland, to a mature height of up to 80cm.

Charlock Mustard was introduced into the UK from the Mediterranean before the sixteenth century and is now found widely across the UK. Charlock Mustard is a branching plant with hairy stems and glossy leaves, with irregularly lobed or toothed edges.

Botanic classification and naming: Charlock Mustard is a member of the Cabbage (Brassicaceae) family. The genus name 'Sinapis' identifies the plant as a Mustard and its species name 'arvensis' means 'field plant'.

Concerns: Charlock has seeds that are poisonous to humans, horses and livestock, causing gastrointestinal upset. Charlock seed also remains dormant and viable for many decades, germinating when the ground is disturbed.

Benefits: Atrracts bee and fly pollinators and provides a food source for butterfly caterpillars, such as those of the Small White. Charlock seed is eaten by birds.

Benefits to wildlife are also indicated with orange icons in the plant profile bar at the top.
