lily of the valley

lily lily of the valley, won't you be my very best pally
.....oh be my lily oh be my lily and I'll be your forget me not

My Mom sang this when I was young and then to my kids. She recently passed away and this song came to my mind. I would really like to know what the lyrics were. I know the tune as well. No search has turned it up yet. If anybody knows this song or anything about it, we would sure love to know.
