Uh, hhmn, you aren't really supposed to insert the floral tape directly into cake either. For one thing, it can come off when you insert the flowers and for another, there are mixed views on the safety of the dyes used and the material itself as to whether or not it is food safe. You need to completely seal this taped wire in plastic or foil or the little floral beakers or the fresh flower spikes as Dawn suggested or something else food safe like the straws as suggested. Or you can do your flowers on round edged toothpicks or wooden shishkabob skewers or chopsticks.
