About

Common comfrey is a hairy plant of damp ground and is found beside rivers, in fens and ditches, and on roadside verges and waste ground. It often grows in clumps and displays clusters of bell-shaped, pinky-purple flowers from May to July. It has become an important plant for organic gardeners as its roots reach deep into the soil making it rich in minerals, while its leaves can be used for slug control, as a fertiliser and as a composting aid.

How to identify

The comfreys are a small group, but can be difficult to tell apart from each other as hybrids are common. Common comfrey has large, oval, hairy leaves, and clusters of drooping, tubular flowers that are pinky-purple in colour.

Distribution

Wdiespread, but most common in England.

How people can help

Our gardens are a vital resource for wildlife, providing corridors of green space between open countryside, allowing species to move about. In fact, the UK's gardens provide more space for nature than all the National Nature Reserves put together. So why not try leaving wilder areas in your garden, such as patches of buttercups in your lawn or nettles near your compost heap, to see who comes to visit? To find out more about encouraging wildlife into your garden, visit our Wild About Gardens website: a joint initiative with the RHS, there's plenty of facts and tips to get you started.
