Could a planet orbit the sun on a vertical plane as opposed to the horizontal plane of the other planets?

I am not sure of terminology, but assuming that all the planets are on the same horizontal plane could another planet orbit on a vertical plane?

Bet of a mess here so I'll make a bit of a tl;dr top-level response:

1. Planets form in a flat plane because they all form from a disc of gas.

2. But if you somehow got a planet in vertical orbit *after* the gas disc had dissipated, it should continue quite happily, and there are indeed small objects in the solar system that do have very very high inclinations in their orbits.
