In this thread, you will see Susan saying to avoid Nanho because she did not get butterflies on it. You will also see Angie saying that she did get butterflies on Nanho Blue.

BUT, if you look at:

Deanna. there are other dwarf varieties that attract butterflies. I tried buzz buddleja 'lavender' and that was a hit with the monarchs and swallowtails...it comes in other colors too
