Odd that I have never heard this song and all three of my sisters and I were in Girl Scouts. I'll have to ask them about it.

When I was growing up, we had coral bells here in Western Colorado; not white, but I always thought they were named that for their coral colour. Then, in a very carefully planned rock garden, my brother also had Lily of the Valley which survived triple digit hot summers. They seem to have even hardier varieties these days.
