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 have both forms of sedum within 10 yards of each other and do find
that butterflies will head for the old original and avoid Autumn Joy. I
planted another variety named "Carl" last year, but as there were so few
butterfies around in my garden last summer it's hard to say yet whether
they like that one very much or or not.

Marjoram in flower is a great attractant for many of the smaller meadow
butterflies, as well as bees and many other insects, I find.
