Alexanders (Smyrnium olusatrum) grow to a height of around 1.25m on cliffs and other coastal sites including waste ground and roadside verges as here in the Newport Wetlands National Nature Reserve. I always seem to miss them in full flower. Here there were only one or two plants with yellow flowers. But I very much like the way the ripening seed heads and stalks look. Some of the seeds are turning red and eventually will be black.
