Sweat Peas

The peas sprouted! I planted these from seeds just a few weeks ago! I *think* the romaine lettuce has also sprouted; but before I get too proud of my gardening abilities, I'm going to give it a few more days to reveal itself as just a weed. (There was a suspciously similar looking sprout in the middle of the onions.... did a seed just accidentally get transferred? Or are weeds eventually going to take over my garden!?!?!) The last 2 pictures are of a different type- and even sweeter species- of pea.
