Mr. Smarty Plants says

Question: We recently were required to put in a new septic system on our vacation property in Door County, WI. This left us with a clearing on our wooded lot where the septic field is now located. The installers said it was too late to plant wildflowers on this plot(weeds as he called them) so they planted grass seed instead. My question is, are there native varieties of wildflowers (such as Queen Anne's Lace, Wild Phlox or others) that could have been planted as late as July or could still be planted this coming Fall? If so I would welcome your suggestions. I am definitely not happy with the stringy unnatural-looking lawn I see emerging in the middle of our nicely wooded lot.
