 Chair Brosnan, WBZ, Boston's News Radio. As far as flowers go, petunias are tough nuts. They can survive in a range of temperatures and in all kinds of places. And that's kind of like Petunia the puppy over at the Animal Rescue League in Dedham. Aptly named. Petunia's ready for a forever home. Ready to be adopted after being found all alone, abandoned and hungry and full of mites.
