I don't like using 2d objects in my models, which is seemingly all that is available on bimcomponents.com.
I ended up fudging it in the end by creating new surfaces based on colourful plant textures and then applying that surface to the leaves of my trees. By creating smaller trees with these surfaces it gives the appearance of plants.
Not a bad workaround I feel.
