Pine Tree

Pine tree branches are produced during upward growth of the main steam shoot, braches appearing in regular "pseudo whorls", (a very tight spiral but appearing like a set of branches all branching out from the same height on the main trunk). Interestingly, the spiral arrangement of branches, needles, and cone scales resemble Fibonacci number ratios (following the numeric golden rule in nature). On Pine trees, the new shoots of branches are sometimes called "candles". The "Candles" consist of a bud scale either brown or cream color, pyramidal in shape pointing upwards, covering a wad of new needles surrounding the branch bud. The bud scale eventually falls off and the needles spread outward.
