I am a weed management practitioner working for a gov't agency in California. I have posted a few weed pictures on this site for outreach and education, but I noted that one commenter appeared dismayed at finding yellow starthistle appearing on this site, apparently intended for plants of horticultural value. Should I stop with the weed pictures?
I hope you will keep posting the weeds--although in addition to the pictures, it's also helpful to add a comment about its weedy behavior if others haven't already pointed that out. Plant Files is a resource for education--without being able to look up what pictures of yellow star thistle how would anyone know whether that's the weed that's taking over their yard. And the comments allow people to research whether or not a plant is something they ought to put in their garden or not--there are some beautiful plants out there that can be thugs in some areas and the comments in Plant Files can help steer people away from things like that. Then there's the complication that plants behave differently in different areas--something that is a gorgeous native in one area of the world can be an aggressive invader somewhere else, so even if someone wanted to keep Plant Files limited to only things of horticultural value, that would be impossible.
Please do keep posting your photos and comments. It's all very helpful, and PlantFiles is meant to be an informational resource for gardeners, and we all know that every garden has a few weeds. We welcome photos of all plants except those grown and used for illicit purposes.
