Those are old Vue plants. Now e-on has released new TPF (The Plant Factory) editor.
I was working on this new editor with e-on for 6 years, and I tell you it is a great beast!
It is better than Speed Tree, and old-timers like Xfrog or Onyx can\'t compete with it anymore. There is a free PLE of TPF available, so you can check it on your own.
Please, check my website about 3D plants editon - a hub of knowledge about virtual vegetation :
