Having walked beneath Rosa mulliganii the banana scented rose on the pergola you re-enter the sunlight again to be greeted with the dark pink flowers of the sterile hawthorn, Crataegus laevigata ‘Paul’s Scarlet’. Beneath its branches can be seen the lime green bracts of Euphorbia characias wulfenii and the colonizing small pink knotweed, Persicaria bistorta ‘Superba’.
