Looks like there's multiple plants in there, one being the lemon lime philodendron

Yes, it's the so-called Lemon-Lime.

Alyssa, the darker leaves do look like another type of philo but these are older leaves that lose the yellow color over time.

I bought one of these this past summer (central Florida), and someone else has posted that they had bought one, who was going to thread the vines through and around a trellis. All have been massively overgrown. I cut a lot of tip and section cuttings and put the main plant with the board into a larger pot.
