You know how one can look at something all the time (in this case all one’s life) and not see it?
The other day, contemplating the Norway Spruce out to the east of Happy Thought it finally dawned on me that it really was different from the others… shorter (all of 80 feet), a darker green colour, narrower cones, bright magenta young cone buds, and….long hanging branches….much longer and much more draping than the normal habit of a Norway Spruce. Why! It is a weeping Norway Spruce. A fully mature specimen and not so extreme as modern cultivars of ‘weeping’ trees; but nonetheless distinct. I shall have to stop and look, halfway up the hill there is another tree that appears similar.
I feel very stupid.

Sounds like the classic case of forests versus trees 😉
The funny thing is that while a young regular Norway Spruce looks very different from a weeping cultivar, by the time they are both over the century mark the difference is fairly subtle. It is a difference of amount rather than kind.
