The forest is a lot more open now and the piles of Rhododendron will soon rot away.

Hemp-agrimony is a tall perennial wildflower that prefers damp grassland and marshes, sometimes occurring in wet woodland. The root-stock is woody and produces round stems, up to 120cm in height.

The stems bear a reddish tinge and are covered with downy hair. Also, when cut it exudes a pleasant, aromatic smell. The basal leaves are on stalks, but the stem leaves are borne on very short stalks. The leaves consist of three (rarely five) leaflets, long and toothed, superficially resembling hemp – hence the English and Latin names. The leaves are opposite

Hemp-agrimony flowers in late summer and autumn (July to September). Its flower heads are small and consist of 5-6 reddish-pink, tubular florets. These are grouped into panicles (much larger groups of flowers on small ‘branches’), creating the appearance of much larger flower heads. The angled fruit, an achene, bears a crown of hairs of a dirty white colour.

The plant was considered a good remedy for purifying the blood, either used by itself, or in combination with other herbs, and as a treatment for influenza or similar.

The site at Oakhill is very lush and abundant with Rhododendron bushes which are totally obscuring the light for most other vegetation to grow so we set about the task of removing some of this. On the edges of the trees a great deal of Hemp Agrimony was growing and coming into flower which is an asset for the butterflies.

We were joined by some members of the Gloucestershire Wildlife Trust and hope to see more of them in the future
