picking wildflowers

[solnishka.livejournal.com]

My apologies if this has been put out there before, and I just missed it. My friends and I want to go pick wildflowers...free, or for a charge. Any information on where we could do this would be highly appreciated. We have a car, so distance is ok, though staying in the area is prefered. (davis square, somerville parks, etc)
Thanks!
