  • Question

    We have a woody stemmed broad leaf vine that’s been growing on a trellis at our house for 50 plus years. We are doing a porch project and need to trim it back BUT don’t want to harm it. Can you tell us what it is so we can research trimming it?

    Answer

    Dear M.hartnett, it looks like you may have the liana Isotrema macrophyllum (large-leaved Dutchman's pipe; formerly known by the scientific name Aristolochia macrophylla). It is a well known liana that is grown frequently, so you should find lots of information on this species.
