No offense taken. Imagine that you cut a disc off the butt end of a 50 year old log and examined the growth rings from the pith out to the edge of the disc. What I was trying to describe is that in the first 10 years or so (varies by species) of annual growth in most trees, the wood cells that are formed have characteristics that are a bit different than the wood cells that are formed after that 10th year (10 years here being used by example only). This first 10 years of growth is called the juvenile core. Once the tree has reached about 10 years of age at a single point on the stem, the wood being put down by the cambium in later years begins to change, having more stable characteristics from a woodworkers standpoint. This wood is called “mature” wood, even though it might have just been formed by the cambium in year 11. The first two links posted by tefinn do a good job in describing these different characteristics.

The terminology can certainly be confusing.
