Anyone know what Fox Hollow allows you to throw at their outdoor ceremonies?

We're having an outdoor ceremony at Fox Hollow and I was wondering if they allow you to do a throw as we walk back up the aisle. I don't really want to do bubbles, just not my thing. But I'm not sure they would allow us to throw rose petals or something else that they might have to clean up after our ceremony for the next.

Anyone know the answer?
