Yes, I agree that they are piped. I guess if you did not feel comfortable piping, you could roll out really think pieces of fondant and freeform them that way.
If you are talking about the side of the cake, they are most likely piped.
If you are talking about the flowers on top of the cake, to me they almost look like they are made from either piped chocolate or piped royal icing. You could do the same by drawing out a template you like on a piece of wax paper, flip the wax paper over and then pipe melted chocolate or royal icing within the lines.
There is a small flower cutter that would cut flowers like the ones standing up. It is in the Wilton Beginner Kit. I think you can buy that cutter and a larger one together but don't hold me to that. You can also look for a fondant mold that Wilton also makes that has flowers that look similar. Michael's and Hobby Lobby are where I would start looking. Hope that helps...that cake is precious!
