Jennifer Garner took her three kids, Violet, Seraphina, and Samuel Affleck, along to pick up plants at a nursery in LA yesterday. While Jennifer browsed the greenery for sale, Vi and Sera took turns pushing their little brother down the outdoor aisles in his stroller. Later, Seraphina and Samuel headed home while Violet accompanied Jennifer to the grocery store and the farmers market. Both Jennifer and Violet had big smiles on their faces as they checked out the offerings, and even sampled produce, at the market stalls. The whole Garner-Affleck family is gearing up for a big Fall. Jennifer's Butter arrives in theaters on Oct. 5, while Ben's third directorial effort, Argo, arrives on the big screen one week later on Oct. 12.
