Foliage on Object

Seems simple buy I cant find a way to paint foliage onto an object.
Specifically I’d like to be able to ‘paint’ grass onto a ball.
I select only ‘object’ and I try painting and it only paints on the landscape object.
I’m sure I’m missing something terribly simple but I would appreciate the help.

In the foliage tool you have different options on what the foliage can be applied to.
you can make it work with Static meshes, or even the BSP ones.
