The bouquet holder must be secured in a vase or narrow necked container that is weighted down with rocks or marbles. The design can become heavy with the weight of the foam and flowers. It must be secured so it doesn't topple forward as you are designing.
My basic greening choice is usually leather leaf fern This versatile greenery is common in every flower shop. It is inexpensive and is available all year round.
The entire stem has many fronds, which can be cut from the main stem.
I cut apart with a floral knife for a clean cut that inserts easily into the wet floral foam.
Framing in the greenery will establish the final size of your bridal bouquet. Remember the tips of the flowers will usually extend slightly beyond the greenery.
Leather leaf quickly fills in the desired shape.
