It hard to see other details i.e the leaves petioles, and the top of the plant is too dark to tell if this is a new leaf or a flower bud?. There are few plants with similar looking leaves. I’m and wondering if this a type of Thalia or a Canna ? Please resubmit with better focus closeups of detail mention above & if you have any more of the seeds to show us for a quicker ID perhaps. Check out this included link below for Thalia geniculata. Click on images to enlarge. Best wishes! https://keyserver.lucidcentral.org/weeds/data/media/Html/thalia_geniculata.htm

without the flowers & seeds to narrow down its ID, I could only speculating for now. Top photo – Maybe a type of Crinum pehaps? Check out one in the genus. When it blooms and you still don’t know, resubmit with flower, fruits photos. Here’s one in the group, the Crinum asiaticum. Again, this is only a specultation; flowers are needed for a confirmed ID. https://en.wikipedia.org/wiki/Crinum_asiaticum
