Ground-elder was likely introduced into the UK by the Romans and has since become naturalised. A medium-sized umbellifer, it is an invasive weed of shady places, gardens and roadsides.

Despite its name, Ground-ivy is actually a member of the dead-nettle family. It is a clump-forming, aromatic plant that likes woodlands, hedgerows and damp places.

A 'weed' of cultivated and disturbed ground, Round-leaved fluellen is a trailing plant with round leaves and yellow flowers that appear over summer.

This unmistakeable moth, famous for its skull-shaped marking, is a rare visitor to the UK.
