Bittercress always grows in a rosette, with its leaves coming out of one central point. It sends up flower stalks from the middle of that rosette. The flowers are small and white, with four petals. The seedpods are thin and upright, along the flower stem. And yes, it's not even the end of March, and bittercress is already forming flowers and seeds here in the DC area.
In your yard: Cultivation is beyond easy: you don't even have to plant it. It's almost certainly already growing in your yard, if you have one. If not, I'm sure your neighbors would be glad to let you have some of theirs!
