So, I've had a dutchman's pipe vine for just a little over a year, and I've yet to figure out if it loves/hate the sun/heat/shade. It's surviving, but that's about all. Most of the articles I've found on line have been uninformative. Then I came across this one below. I don't think I have the giant variety, but since my vine has yet to bloom, and I'm perfectly happy with that, I'm sure I'd cut the flowers off anyway, how would I know?

I don't believe we have this type of butterfly in our area, but now I'm wondering if it is toxic to other species. Anyone know much about Dutchman's pipe vine?

It would help if you posted some photos of your plant.
At my house, the pipevine swallowtail uses the native Aristolochia serpentaria...



but ignores the White Veined Pipevine (Aristolochia fimbriata)



ANd... the butterfly is very similar in appearance to the black swallowtail...



Really doubt that cutting the flowers off would help... it's the leaves that the caterpillars eat...



Ok... apparently the pipevine swallowtail is NOT in Oregon.
