Sedum spectabile is commonly listed as a good butterfly plant. Without
a doubt it can be. One flat I lived in had a garden below it that was
always full of red admirals on the sedums in the Autumn.

However, in butterfly circles people are commonly warned to avoid
Sedum "Autumn Joy" also known by its German equivalent name of Sedum
"herbstfreude". It would appear that it is of hybrid origin and
produces less nectar and is therefore much less attractive.

It seems there are other cultivars/hybrids that are also unattractive.

I'd be interested to know of other people's experiences with named
cultivars.

What have your experiences been?

There's been discussion on here before about buddleia, IIRC to the
effect that darker purple forms are less attractive. Google groups
search might throw it up.

I think I recall that. I would expect the wild colour to be the
best.Since that is what attracts the pollinators which leads to more
seeds and more copies of those genes in circulation etc.
