I posted PhylloMachine, Grasshopper plugin to model plants. I leave here this announcement if anyone is interested in help to implement L-System in this plugin. I need someone with that experience and want do so in his spare time. Once you know the plugin, you will understand how wonderful it would be to use simple rules to model it.
PhylloMachine is written in ghVisualBasic and it’s open source. You can find it here:
Interested please contact me via email to firstname.lastname@example.org
