THE PINE TREE THAT BLOOMS ONCE IN EVERY CENTURY

Pines have male and female reproductive organs. They are located in different places on the same tree. Pines do not have true flowers by definition, as the female reproductive organs do not have ovaries. However, there is no harm in calling the reproductive organs as flowers.



Many of the male flowers of the pines together form the male inflorescence. In the same way, many of the female flowers together form the female inflorescence.

Now let's take a look at the male and female flowers of pines. Bud-like structures seen below form male inflorescence.


When these male flowers open and start to pollinate, an image like the one below occurs. If you look carefully, you can see the abdomen of an insect with its head stuck in the topmost inflorescence. Male flowers start to dry and fall after about 2 weeks after the pollen scattering process is completed.


Below we see two female flower at the end of a shoot.


Female flowers grow up to 2 years on many pines. At the end of the 2nd year, at the beginning of the 3rd year, they open with the effect of heat and scatter the seeds they ripen inside.


Here is the wonder flower of the pine: actually the cone we all know.

Pines arrive at bloom maturity at varying ages depending on the species. Red pine (Pinus brutia) can bloom at the age of 6, while black pine (Pinus nigra) may need 20 years of age to bloom. A pine that has reached the age of bloom blooms every year, not once in 100 years.

There is no pine that blooms once in a hundred years.
