Greetings and Welcome!!
Yes, yes, yes. There in Reston/Herndon area, depending on how much land you have, you will be able to grow lush wonderful fig trees either in either pots or right in the ground. Troll through the forum here and you will see that there are folks successfully growing figs all over the US of A. Funny that the Lowes salesperson discouraged you, in the springtime, Lowes was selling 100s of Black Mission, Hardy Chicago, Brown Turkey, possibly more.
Wanted to add that if you live on a smaller plot, or townhouse, you can easily sneak many plants in pots. The only requirement is a nice sunny area so your plant receives maximum amount of sun.
good luck!
zen, here's what you can expect, i attached a photo of Hardy Chicago that we just picked tonight.
