Super Leaf - or how to make Spring trees

I made some fun purchases at Scenic Express last week. One of them (some of them?) were Super Leaf packs in many Spring colors - pinks, purples, etc, so I can continue in my quest to add color to my boards. I already have Fall colors for my trees, but I decided that Spring has great color and I wanted to experiment.

Purple Leaf Plum Trees

One problem I found with my desire to add Spring trees to my table was the apparent lack of ways to do so. I usually either buy trees off Ebay, or use various methods combined with Clump Foliage to make them - but this didnt seem like an option for Cherry, Dogwood, or Plum trees.

I found this product: http://www.sceneryexpress.com/JAPANESE-CHERRY-LEAF-PETALS-16OZ-SHAKER/productinfo/653-6542/ and shortly after found this review by TerranScapes...but as you can see, it still doesnt really give a good example of how to make these trees (yet?). Skip to 2:16 for the review...or follow the link he adds in the upper right hand corner as the video starts.

I'm still at a bit of a loss on how to do this, even though I have this neat product - because it doesnt seem thick enough to make trees with in my usual way.

More research is needed. I'm wondering if anyone has experience with this product?

NOTE: I found a new item in Catalogue #17, called "Pull Apart Plant Cluster" (an example is here):

It looks to be an undercoating, if you will, in the vein of the Polyfiber product. I may look into this.
