Daisy Chain

In looking this one up all I find are technical articles or stitching patterns.. can anyone help with the origin or meaning of this phrase? Thanks!

I have a CD of old show tunes. There's one that says something like, "I used to be on the daisy chain, now I'm a chain store daisy." I took this to mean there was some short of chorus line dance with young girls and daisies linked together. And wasn't it once a custom to make necklaces and "crowns" by linking daisies together?

Easter daisy chain - verse from an online card at card at www.bluemountain.com

how do we go out and face the world is the same question as how do we pick our friends?
. . . dearly, like gems.
carefully, like flowers.
the moments we remember best stay with us like a daisy-chain;
like a necklace made of flowers, worn with familiarity and love, and close to the heart.
we arrange them until they become something beautiful and walk out into the world holding hands.

This was wonderful information - thanks again!
