Several websites carry an anecdotal story that claims that pine trees begin their new growth around Easter every year, and as Easter approaches, most of the new growth takes on the shape of a cross. Is there any basis to this? Of course new growth happens at Easter because it's Spring, but the fact that Easter is not a "fixed" holiday leads me to believe this is a stretch. I couldn't find the answer on, through a Google search, or through your library or search. Thanks!
