Variations between individuals

The Eucalyptus offered are not clonally propagated and therefore will exhibit some differences between individuals within a species.  Characteristics such as growth rate and bushiness may be the most obvious.

To understand how much difference there may be we must understand the normal distribution of a population.  This describes the likely outcome of random events.  It is represented by a standard deviation curve.  e.g. The mature height of a human male population

As you can see about 95% of the population will be between 5ft 3ins and 6ft 3ins and about 66% will be between 5ft 6ins and 6ft.  There will be very few dwarfs and very few giants.

The growth rate of Eucalyptus are affected by soil type & fertility, length of growing season, amount of exposure, weed competition and availability of water.  On the same site with identical growing conditions the vast majority of individuals of the same species, once established, will grow at a very similar rate.  However, because of natural variation, there will always be a few that noticeably grow faster or slower.  This is the way things are.
