FAKE FLOWERS?!?!? Sacrilege! Sacril..... Just kidding. Actually, I just saw a silk flower topiary in a catalog last night. It was the kind where the top is a "ball" of flowers, made up of silk rosebuds. It might also look pretty to use topiary forms like circles? and wrap the flowers on with florists tape or glue them on.
You might be able to do real ones out of some kind of little ivy? or herbs? if you started soon.
Hi,
I have instructions for making a Live Ivy Topiary. I have a method that I call the Quick Start Method. Basically you are propagating ivy on the sphere of moss. It is a more expensive but quicker method than the standard method.
