Their website doesnt inspire, but if you check out the animations on http://www.xfrogdownloads.com/greenwebNew/products/productStart.htm - ones like Growing Trees then you will be amazed. Xfrog looks like the procedural engine - then there is XfrogPlants which is like a library - but it doesnt cover aussie plants and seems relatively restricted? That said the images below show a wealth of power there somewhere!
