Lily of the Valley - Takes Me Back

I'm really enjoying participating in Lori Moon's May Flower Challenge because everyday I get to visit other bloggers' beautiful posts filled with flowers.  Yesterday as we picked our daughter up from a sleepover I noticed her friend had tons of lily of the valley under some pine trees.  Had to pick some of course!

I've loved these flowers ever since I was a little girl; the smell takes me back to being young and running around with the neighbor girls.  We don't really have any shady spots in our yard so I've never planted them, but I really really would love to have some in our yard instead of "stealing" them from other yards!  Isn't it odd how the scent of flowers can send you back to an earlier time?  That's what lilacs, peonies and lily of the valley do for me.  Takes make back to being young, much more carefree and pretty much clueless about what growing up would really be like once I got there.  How about you?  What flowers take you back in time? Make you just say "ahhhh"?
