Today I finally made the decision to remove a bunch of plants (actually my boyfriend did it) that I thought may be a type of weed. I don't know much about gardening, but I didn't like the way this plant looked and it was always wrapping itself around everything mostly the roses the were beside it. They had tiny little thorns,(or at least something like that) which cut me at one point. They recently grew some small little purple "berries" that would hang off of it. I smashed one in my fingers and it didn't smell sweet , but was VERRYY sticky. It was bushy and resembles some type of fern- Please excuse my ignorance about plants! Anyway can anyone tell me something about these plants. I still have them in a bag right now and will probbaly replant a few if it turns out I made a huge mistake. Thanks!
