Pittosporum comes in both variegated and solid green. Since my flowers are monochromatic (all one color), I introduced a little more contrast by using variegated leaves as part of the design.
Here is just one single grower's bunch of pittosporum.
Each stems have very many leaves that work well in bouquets, corsages and boutonnieres and corsages.
There is also boxwood - little smaller leaves.
Continue inserting these smaller leaves into the design, filling in the florist foam.
Keep in a fairly circular pattern, working your way into the middle.
