Pete :

:) there's always a catch... this is a limited version without all the modeling / animation tools that you can find in the latest Xfrog. But it's nevertheless a complete software (no 30 days limit).

jstro :

Xfrog is quite easy to use... It's a modular procedural software : the plants are made of an hierarchy of elements (root, tree, leaves, etc...). There is actually no modeling involved.
