Hi could be Astlibe or Aruncus [there is a dwarf form]. did it flower for her last year and can she remember what it looked like?

Wrong shaped leaves for Aruncus aesthusifolius.

Thanks Owd 👍

Looking again I wonder if it is one of the forms of Persicaria?
Could really do with a closer view of the leaves to be sure.
Astilbe does look a good id as well.

Thank you, Owd. I’ll put it to her and see if any ring a bell from buying them - she lost the labels. She enjoys gardening but admits she is forgetful re labels and names.

Looks very much like Astilbe Kate.

Thanks Julia, I’ve passed this info to her.
Much appreciated, thanks all 👍
