Illustrator: apply clipping mask to group


Here's the problem I have:

I have a large group of objects that I want to apply a clipping mask to. The large group of objects are in different colours, so I can't make them a compound path. But there doesn't seem to be a way to apply a single clipping mask to them because you can only apply a clipping mask to 1 object, not a group of objects. So what do I do in this situation? See below for illustration of what I mean (simplified, this is not what I actually have, each flower is supposed to have different colour).

As AndrewH mentioned in the comments, this should indeed not be a problem. Are you sure the path your will be using as the mask is on top of the flowers? In your illustration it isn't.

When instructed to make a clipping mask, Illustrator clips the bottom object with the top path. In your case, if the top path is a group, it will refuse service.
