Great looking gloriosa Daniel! Gloriosa will continue to trunk at that size. Hopefully you'll only get one new leaf head, sometimes multiple leaf heads start to grow and the appearance gets a little messy. Try to pollenate it but likely too late as freezes are not too far away. I have a gloriosa 'Tennessee' from Rob O which is blooming now. Where did you get a gloriosa 'Faxoniana'?
