Ghoran Druid?

[Ectar]

So, ghorans might be the coolest race in the game.
I was wondering, though, could a ghoran druid actually use wildshape?
Plant creature are immune to polymorph, which makes me think no.
However, I've seen other forums where people think they'd make good druids. I suppose they could still be caster druids, but not being able to wildshape at all takes away a huge class feature.

Wildshape is a supernatural ability, it acts like polymorphing, but I believe the Ghoran would be able to use it because it's a gained ability. I looked up plants that do it too; The Boruta (http://www.d20pfsrd.com/bestiary/monster-listings/plants/boruta) has wildshape, so I'm pretty sure a Ghoran can gain it as well.
