A single bunch of tree fern goes a long way and is a perfect (and cheap!) way to add a light feathery feel to your bouquets and corsages.
Here is a single stem that has lots of individual laterals that can be snipped off and inserted into foam.
It's common name attributes to the look of a miniature tree with lots of branches.
I don't want to overpower my design with too much, but if you want a stronger look simply add in more laterals as a mass.
Here I've pulled back to show a bigger view.
Here is a look at all the greenery together.
Next I'm going to add in more Lily grass at the bottom. But instead of loops (as I did at the top) I'm going to leave them as a long, unbroken sweep of grass to draw the eye downward to the length of the cascade.
