The message
from Sacha contains these words:

The copy of the RHS encyclopedia I'm looking at now says:
"Polygonumm bistorta 'Superbum'. The picture is of a 'vigorous,
clump-forming perennial that from arly to late summer produces spikes of
soft pink flowers above oval leaves.' It grows to about 2.5' and spreads to
about 2'. This copy was published in 1989.
The 1999 version says "Persicaria bistorta syn. Polygonum bistorta 'Superba'
and to me, the two pics look identical. HTH

What makes you think that the name 'Superbum' might have been chosen
without writing it down first?

Good one, isn't it? ;-) I'm assuming the original namer pronounced it
'superb um' and as you say, didn't write it down!
