If you are using fresh flowers you will need to do some research into which flower type would work best. Generally the best flowers to use are ones that hold up out of water such as rosemary, lavender, berries, spray roses, strawflower, wax flower, eucalyptus, tiny chrysanthemum blooms. Choose statement blooms that have long, thin stems for the best effect. In the winter you could use greenery and winter flowers and berries.
