The super glue idea sucks because it will kill or mame the plant but camo'ing the plant works well,ive done it.
Instead of gluing fake flowers use fake vines & stuff them all the way to the bottom of your pot,use vines with bright color small flowers on them like bright yellow or dark red,make sure that you have other colorfull plants next to it so it dont stick out.
Camo works pretty good,ive used fake red berry vines with outside grows for years,at a glance they just look like a poison berry bush & hunters keep walking.
