I know this thread is a bit old, but, I bought the Botanica add-on for Vue 5 Esprit, and I'm pretty dissapointed. The options are very limited, depending on groups available within a plant. I was expecting to be able to manipulate plants like you can manipulate terrain, bit not so. So, in short, I can't make the kind of palm tree I want out of the types inherent to Vue 5 Esprit. Can't adjust the taper of the trunk. If I chage the trunk diameter the whole trunk changes, making it even uglier. The claim that you can create whole new species from existing ones is a stretch, at best.
