Question
I would like to do a 28" eiffel tower centerpiece for my wedding. How many large calla lilies can I fit in one vase? Would 3 stems and a few stems of bear grass fit? I'm ordering the callas from Costco.com.

Answer
Hi,

I'd have to know the size of the vase - diameter of the neck and stem, before I can tell you.  You can assume that the stem of a regular size Calla will be about the same diameter as a dime.  They can't be packed too tightly, though, as the blooms need breathing room to really show off their form.
