Callas are long lasting.
If you decide to use an Oasis holder for the callas: I wire and use wood picks, and also glue around the stem as I go with the tube flower glue. I have found the spray glue will sometimes "melt" the Oasis.
Anyone else have this problem with the spray flora lock, or was I using too much?
Collaborated on a large December wedding and did the church decorations and reception centerpieces. Another florist did the calla lily wedding party flowers, (selected by the bride). The callas were in Oasis holders for the bouquets, and were simply stuck into the foam, and were not secured. Needless to say, the calla's were falling out at the church. I stayed after the ceremony to clean up, and found several calla's on the floor, from the bouquets. Even calla's in the altar arrangement (also in Oasis), had lost 2 of its' callas.
A note about calla bout's, I wish I would have glued orchids to calla bout's for a wedding this past summer, as the wire did not hold the orchid very well for extreme hugging.
