I grow buddleia as a full size bush in the back garden. Yes they are almost impossible to kill. You can cut them back to a few inches tall after flowering and they will be ten feet tall by the end of next growing season, it astonishing. As for bonsai buddleia it is something i have been experimenting with over the last few years, quite simply because i have an abundence of them.

The root from cuttings exceptionally easily. They take a while with almost no roots and then shoot out millions almost over night. I've managed to get some nice nebari in this way.
Air layering is also another easy cultivation method, with them taking in about a month on old wood. I havent tried any on new growth yet.
The leaves do seem rather huge as a full size specimen, but i've got them to reduce down to about an inch long, which aint bad.
As for the massive flower spikes which themselves can be about a foot long, i have found that on 1 year old plants from cuttings they flower well with spikes only a few inches long.

I'm working with a few cultivars and havent as of yet got anything substancial, i'm just learning. Give it a few years and i might be able to present one to everyone. Until then, i'll try and get some pictures and maybe become a bit of an expert in buddleia as bonsai.

Failing that i may end up turning round and saying it doesn't work. lets wait and see.
