Hello everyone,
I have this new offshoot and I do not know which plant this is. I would say it is some kind of succulent due to the leaves, but I am no expert... could you please help?
Thanks in advance :)

We need a size reference.

Plant it and see what it grows into.

I suggested your inquiry be moved to the cactus and succulent forum where the experts hang out.

I do not recognize it. If nobody else knows what to call it, you might need to let it get bigger before a proper ID is possible.

My suggestion would be to remove the lower 2 leaves and cut along the line with scissors or a sharp knife (or whatever line results in about 1cm of naked stem on the cutting afterwards)



That will give you a piece that you can seat upright in the soil. Use soil with good drainage (like 50% pumice/perlite/equivalent) and avoid an overly large pot. Wait 1-2 weeks after making the final cut to water for the first time. Put it in strong light (as strong as possible if this is an indoor plant) and wait 3-4 weeks for the cutting to root and start growing.

You may be on the cusp of possibility here at the very end of summer, given the northerly location and the shorter/darker days ahead. But you should be able to get it somewhat rooted before winter hits. At that time you probably have to ease off on the water for a while, if you're relying on natural light.

Standard succulent care is strong light, good drainage, water when the soil is dry or almost dry.

An addition to Baja's suggestion. If it were me, I'd also keep the two leaves removed and see if the leaves themselves might grow a new plant. What I see in the photo makes me think it's the type of plant that can do that. That would just be two more chances of preserving the plant.
