Making rose boutonnieres special can be as simple as adding a mix of different greenery. Leather leaf fern is commonly found in every flower shop.
It holds up very well for cut work such as corsages and boutonnieres.
I spray my fresh greenery with Leafshine. This product seals the leaf and slows down moisture loss, making the greens last longer.
You can easily cut off the individual fronds for use with boutonnieres. Allow the sealant spray to dry before designing with the leaf.
Place a single frond directly behind the rose head so it peeks above the top of the rose.
As you can see, this makes the leather leaf stick straight out backwards. The next step will show you how to overcome this flaw.
