I've got one lupin that does well in normal years but this year was so wet it got munched by slugs. It does get the aphid problems but if I get there early and squash a few, natural predators tend to take care of the rest. If I don't get there early then spray them off with a burst of water and it seems to work well.
I grow lots of echinops as well and they seem to always get covered in blackfly but I use the water squirting method and they seem to be fine. This year however I barely saw any pests at all, didn't even get any on the broad beans, and I don't know if it's because I increased my diversity of helpful plants or they just didn't make it through such a harsh winter (bees, apart from bumblebees, seem to have been at much lower numbers this year in the garden).
