in people's experiences, what are the best plants for attracting butterflies apart from budeia.
Lots of info here
Marjoram is a good one.
Sedums are very good Justin, and easy to grow.
I bought some eupatorium last year and they were covered in butterflies and bees all the time they were in flower, but they are quite tall, but also architectural.
I second Euphatorium, very attractive to butterflies! Also Aster 'Little Carlow'.
Lots of butterflies on my Echinacea flowers last year
I've planted sedum, liatris, lupins and butterfly weed now as well as the buddleia
