My personal interest was aroused by the occasional patches of orpine (Hylotelephium telephium subsp. fabaria) I came across in Brede High Woods, East Sussex. Where it occurs it seems to grow and flower quite well in shade or semi-shade and is considered to be an indicator of ancient woodland. It also grows by wayside hedges and ditches and I know several sites where it occurs in our parish of Sedlescombe. It is our only native species of Hylotelephium though some others have escaped into the wild from gardens and parks.
The picture below shows how it grows in Horns Wood near Brede. The stems lay themselves down naturally and, as they can root and produce new plants from the leaf nodes, the species is able to spread vegetatively. Seeds also germinate quite freely in the spring after they have set.
