What type of flower is this?

I was cutting this guy's lawn, and he had these white flowers that were along his fence. I asked him if could have some, and he said I could take them all if I wanted, he thought they were weeds. I guess there wild, because he certainly didn't put them there. I dug them out by the roots and put them in a couple places at my house, they are doing ok, but by next year i think they will great since there roots are big and I didn't cut them. They almost look like apple blossoms, there white and have a slight pink in them. They smell really sweet, and they are mostly 2 feet tall. They have bunches of flower on each branch, and they 5 petals. Any suggestions? What are these flowers?

ps. i don't want to waste another question, but have any of who ever grown fireweed, or had it? thanks.

Reply:I need either a picture or a much better description, i.e., how are the leaves shaped?, how is the flower shaped?, how tall is the plant? when did it bloom or where is it planted ( state or planting zone)..
Reply:RScott hit it! (so give him your vote) I'm just adding an image that really shows the plant:
