They must be doing the same thing along I-80 as well. For several years, I have been seeing these patches of bright pink/purple flowers here in NJ and been wondering about them as they looked too regular to be entirely natural. I love them and they add some much needed color to the landscape.
Yes! It's a statewide program. There's a specific jughandle at the 78/Turnpike interchange that has a nice patch of flowers every summer. It's funny seeing it amid all the industry and crud of the area.
Oh, neat. The annuals make for a stunning field. See my top-level comment for an album of photos I took in a cloverleaf.
