Bonnie McLaughlin lives in a tree house. At least, that’s the way it looks from the front porch of her wood frame house on Fairweather Lane. Butterflies cavort amongst the leaves of the Beach Sunflowers, and hummingbirds feast on the nectar of the Yellow Necklace Pod. The entire home is nestled in the cool, shady embrace of the surrounding foliage. How did this come to be? Is Bonnie some Master Gardener? No, she simply decided five years ago to plant only native plants, a decision that has earned her a certification from the National Wildlife Federation and the envy of her neighbors.
