How big is your baby?

Spring time is a time of rebirth and renewal and much focus is given to cute bouncing bundles of joy like this one

 

and in our area, babies like these…

Yesterday I was out looking at other babies.  Subtropical fruit babies.

This is an avocado pear

 

and some baby mangoes

 a litchi

and some oranges (not on the farm we live on)

So here is what I am pondering…………

All of the above fruit trees blossom and start bearing fruit around the same time (spring)

We will be eating the mangoes and litchis by the end of this year  (3-4 months to mature ripe fruit depending on cultivar) yet the avocados and oranges will only be ripe and ready in 6-11 months time (winter fruit for us).

Why would some fruit be able to ripen and mature so fast and others take so long?
