Juniper and Lamplight

Listening to an old Simon and Garfunkel tape (you remember those?) I heard the phrase "We walked on frosted fields of juniper and lamplight."

Now I know what juniper is, it's an evergreen. In my mind, all evergreens are pines or cedars. Juiper is a cedar. But what is lamplight? Is it a flower? I can't find it and google is no help.

There's also a phrase "Pressed in organdy; Clothed in crinoline of smoky Burgundy."
I had to look for "organdy" and "crinoline". Impressive. (look for it yourself)

I've heard the song many times before, but never looked for the words. Now I'm even more impressed. What a neat song. Those guys could write some good love songs. Not too sappy. But deep. Oh the song title is "For Emily, whenever I may find her".
