Swede and parsnip good bed fellows?

Its the first time for me with roots brasics ect, I tend to poke things in where I have room.

I've ended up with swede and parsnips mixed  together, they booth look well and are about eating size. The parsnips have poked thier leaves imbetween the swede which are
more open and spreading.
Has any one else found this sucessful or other combinations for small spaces.
