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.

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.

Unsurprisingly, the chalkhill blue can be found on sunny, chalk grassland sites in southern England. Clouds of this beautiful blue butterfly may be seen fluttering around low-growing flowers.

The common blue butterfly lives up to its name - it's bright blue and found in all kinds of sunny, grassy habitats throughout the UK! Look out for it in your garden, too.
