I've seed bombed all over LA, getting things growing in nearly unreachable spots that seem to be ignored by civic workers .. there is no greater feeling than coming back a few months later and seeing a thriving collection of plants where once there was a dusty patch of ignored dirt. Key thing though, is to use native plants and not get too invasive with the seed mix. For this, I suggest folks who want to do the same sort of thing, find a local seed business that deals with the native species.
In rural areas, they do a lot of farmer education. In suburban and urban areas, they typically run hotlines where you can ask gardening questions and may run classes.
Ah, that is a very cool idea. Yeah, I imagine that there is a lot of great advice to come from such a resource.
One thing I wanted to do but never got around to, was research the butterfly-friendly native species of California, and then seed-bomb the living crap out of all the sterile gardens in the Hollywood Hills .. definitely a guerrilla action, but if successful one of immense value to say nothing of the beauty of it. Never got around to it though, and the country I currently live in is already quite a friend eco-sphere for native butterfly and insect species i.e. they kicked out Monsanto and already promote the propagation of native weeds and other non-agri species which the butterflies love..
