It's hard to say with it still being so small, but back in the 70's and 80's in the area I lived at the time, there was popular houseplant that we had .... I think we called them "String of pearls" ... which had lon vines of small green pods that hung down from the planter. This looks like it could be something similar ... but since I haven't had even a silk plant (let alone a living one) in my home for over 20 years, I'm not sure that I'm likely to be much help beyond that!
