Post them in this club,
link, or possibly in both. Your poetry is both creative and writing, so it is appropriate to both clubs.
Now, as to where to post them in the club: if the poem is 25 lines or less, I'd post it in a forum thread. For an article, I'd encourage you to post longer pieces and/or post several poems together (with a separate title for each in the article - you could also set them apart with images if you wished). Places inappropriate to post your poetry if you want any chance of positive feedback: quiz, picks, answers. Videos are fine if you can make a narrative flow while still showing your poem, with a beginning, middle and end. A good way to do this is to read the poem on video, either to the camera or over a slideshow. Images can work with very short pieces, but I personally would avoid it. Users tend not to linger on images for very long - certainly not long enough to read verse.
