You know, I never considered that my front yard garden might be against the local laws. I live in Ohio and wanted to take advantage of every bit of our short growing season, so I planted tomatoes, peppers, kale, Brussels sprouts, and leeks in my front yard. I added some dahlias for a bit of color. Anyway, I think the overall effect is quite pretty. It seems strange that communities would legislate that sort of thing.
I also don't understand our obsession with grass. You are quite right about it not contributing significant value. I'm currently encouraging the clover in my lawn to take over the grass. I have faith! 😀
