Producing flower heads of dinner plate size in the copse is a young specimen of Hydrangea sargentiana. Stout stems bear the terminal corymb, flat at first and then as the head matures takes on an undulating appearance. The head is composed of many small light purple fertile flowers, all lightly scented. These individual five sectioned domes burst open and reveal seven or more protruding anther and filaments. Beneath is a split stigma/style. A spattering of larger white infertile flowers sits to the edge of the corymb. The young growth is distinguished by a covering of bristly hairs; this disappears on older wood which has an attractive light brown peeling bark. Native to Western China where it was collected by Ernest Wilson in 1908.
