I made a little collection of fibermesh presets for branches and leaves. Unzip them inside the ZFiberPresets subfolder so you can access them easily and see the icons in lightbox.
The leaves fibers are meant to grow on top other fibers like the Branch fibers I included in the collection.
To render them properly you have to set the subdivision to 0 in the Fibermesh BPR settings sub-menu.
