"If you are a bird or a butterfly, what are the three things you need?" Thomas Condenzio asked the 11 attendees at Lee Senior Community Center's class Aug. 26 on “Making Gardens Bird and Butterfly Friendly.” "Water," one shouts out. "Food" two others offer in tandem. "And what is the last one?" Shelter is the answer. Condenzio holds up a flowering purple verbena. "Purple is very attractive to butterflies, and you need to have pollen-rich flowers and keep them going all season." Bill Copeland, the other team member and organizer of the program says that Home Depot pairs up with Arlington County to offer sessions once a month at Walter Reed Community Center and Lee Community Center. Next month is "Lawn care for the Fall" and October is "Energy Preparedness for the Home and the Car."
