Hi there! I am having a very difficult time identifying this houseplant. Can anyone tell me what this is? Thank you!

Jasmine?

I agree with Sue, it does look a lot like a jasmine, but which one? I can't recall one that has those long, upright panicles of blossoms.

Are the flowers scented? Jasmine leaves are generally shiny and leathery in texture. I can't tell if those few leaves in your picture are.

Could you possibly post another picture showing more of the leaves, please?

Looks a lot like Jasmine to me too but I have no idea as to which one.

Actually my first thought was perhaps a Stephanotis; the leaves look about the right size.

Stephanotis

Can you add an image of the flower so we can see inside?
Also, can you provide a general locations as a houseplant in one place can be a yard plant in a different place.
The only Stephanotis I know are at the florist and to my eyes the flowers do not look right; much closer to Jasmine but I'd like to see more photos.

Although my Stephanotis (Marsdenia floribunda) never bloomed, that's the first plant that came to mind.

Are the blooms fragrant? Both Marsdenia floribunda and most Jasmine are quite fragrant!
