I'm trying to replicate this gorgeous leafy cake, and I'm considering how to attach the leaves.

Do you think they are wired in some way? Or just glued on? Anyone have any tips for this? Thanks

Not sure which cake you mean...the link takes me to the knot's homepage, and I can't see any cakes there.

Okay I found some cakes...do you mean the one called 'Earthy Green'?
I'm thinking they could easily be glued on with a little royal icing, or gum glue. Most of them are very flat against the cake, so I don't think they're wired.

They look glued with either royal icing, buttercream or perhaps chocolate. They don't look wired. If you make these be sure and use gum paste and not fondant because gum paste can be rolled very thin and it dries hard and pretty quickly. They would be much lighter than fondant leaves and would hold on easier.

sorry, I forgot the knot does that.

I don't have a picture to share (I was just so glad to get the cake done and delivered that I completely forgot the camera) but I did a similar cake last year. After piping the vine, I attached leafs with RI. The leaves were made from green tinted white molding chocolate, cut and veined just like sugar paste. I had tried to make the leafs by painting the chocolate onto real leafs but there were too many leafs and they broke too easily. Good luck and let us know how you finally do it.
