I noticed that there are Fringecups (Tellima grandiflora) growing all along the river bank of the Calder from Tenterfields to Copley.
They seem to always grow with the similar Pick-a-back-plant (Tolmiea menziesii)
I also spotted a rare plant, probably also a garden escape, Perfoliate Alexanders (Smyrnium perfoliatum) which I have now seen at three spots along this stretch of the Calder.
Very interesting that the Tolmiea and the Tellima grow together Steve. They both seem to be spreading.
I first saw the Pick-a-back plant, Tolmiea, beside a small side-stream in Hardcastle Crags about 20 years ago.
The Smyrnium is new to me.
