About

Hemp-agrimony is a tall plant found in damp grassland, marshes, fens and wet woodlands, and along riverbanks. The frothy, pinkish flower clusters appear from July to September and are very attractive to all kinds of insects including butterflies like the Small Tortoiseshell and Red Admiral. Its common name comes from the resemblance of its leaves to Hemp or Cannabis, although it is not related to it.

How to identify

Hemp-agrimony is a bushy plant with trifoliate leaves (with long, toothed leaflets) that appear in opposite pairs along the reddish stems. The stems end in clusters of tiny pink flowers that give it another common name of 'Raspberries and Cream'.

Where to find it

Grows throughout the UK, but predominantly in Wales and the south of England.

How can people help

Human activity, including the drainage of land for agriculture and development, has resulted in the disappearance of many of the UK's wetlands. The Wildlife Trusts are working closely with planners, developers and farmers to ensure our wetlands are protected. You can help too: add native plants and flowers, such as Hemp-agrimony, to a wildlife-friendly pond and its margins, and provide shelter for amphibians and nectar for insects. In partnership with the RHS, The Wildlife Trusts' Wild About Gardens initiative can help you plan your wildlife garden.
