Evergreens are just that: trees which don't lose their leaves in the fall, but keep them (or the needles which are a manifestation of leaves) all year round. This is not to say they don't experience distinct periods of growth.
This morning when we walked in Mount Royal Cemetery I was delighted to see that the boxwood hedge (always hard to grow in this climate) was covered with new growth on the tips of the branches.
This is not a shot of the boxwood--didn't think to take a camere, which is always a mistake in this marvelous season. The photo dates from last year, but shows the same lucious, almost luminous green of the new growth.
