Tall perennial with pinkish-purple flowers in woodland margins.
No interactions present.
Foxglove leaves are hairy and a lot wider than willowherb, and foxglove flowers are tubular (like the fingers of a glove).
Rosebay willowherb looks fairly similar from a distance, with tall spikes of pink flowers, but the flowers are smaller and with separate petals (and long seedpods that split open to release seeds with 'parachutes').
Thanks for differentiating between the two flowers. You are right; this was the nearest I could safely get to them with a close up focus lens. Regards.
