Don't see how Rebel3d, C3d already sells a HUGE variety of solid growth plants(remember C3d & EON are the same basically)...If they enhanced the plant editor we could see a lot more more varieties :) In the solid growth area :) In addition, since the leaves are only alpha planes & not REAL geometry - they always look odd - sometimes floating(unattached) or turned so sideways they are flat.  So even though the species look good - they are far from real looking. No offense to the makers - just a fact due to having to use alpha planes & them getting all twisted up.

As a side, solid growth flowers are severely lacking - sure you can start off with the bonny clump - but if look at it the leaves are attached backwards LOL - takes a bit of fiddling to get those to look "normal" once you've redone the "hotpoint".
