Sorry for the ambiguous description, I'm new to plants and this little baby plant was actually in a pot with a portulacaria afra that I bought. I decided to leave the tiny plant alone because it didn't look like a weed. I'm pretty sure this is a house plant that somehow snuck into the portulacaria pot at the nursey, probably from a seed. Looks like it will a nice looking, large plant because in just 3 months or so it's gotten big. It doesn't look like a succulent. And the stem is a reddish hue. Thanks for any tips, have a great one!
