They also talk about needle foliage being called juvenile foliage because of the reason you just exposed. That is why it is called juvenile foliage, because chinensis show it on their early years, but it doesn't mean it is a juvenile thing for all trees.
Yep, that's what I said. Needle junipers only produce needle type or juvenile form foliage.
Procumbens are needle junipers... yet they can produce scale like foliage or what is called "mature foliage"... it is on the book, and I've seen it. Here is a post where this is discussed in other forums:

Here, people are trying to achieve scale on procumbens, which is rare. And most of the arguments are that you won't achieve a Procumbens with full scale like foliage. The book argues that when it happens, it is because the tree is stressed, so not necessarily a good thing for procumbens. I do however, have to go back and revise this chapter to make sure I am not making this up. Interesting conversation.
