One of the popular fruits nowadays is the soursop.  This fruit became popular when its therapeutic benefits were discovered and discussed everywhere and even more when it was purported to be anti-cancer.  The Malay name is Durian Belanda and from at the young stage when the fruit is formed, it does resemble a durian.

The beginning: the flower bud
As the flower forms, it is heart-shaped and green in color.
As it develops, the outer petals open, revealing and inner layer.
When the inner layer opens, it indicates that it is ready to be pollinated. Some have said that pollination occurs at night, so night pollinating insects are important.
Once it has been pollinated, it forms into a brown fruit bud. Some have mistakenly think that this means that the flower has dried up and not fruit has formed thus they remove it.
More “spikes” begin to form towards the stem of the fruit. The color is still brown.
You will get this brown spikes ball.
It begins to increase in size and you can see the inner green skin.
At this stage, to me, it does look like a small durian. The spikes have spaced out and you can see that it is turning green.
As it further grows, the spikes get filled-up and shorter and the fruit morphs into this green fruit with shorter spikes. The whole time from the flower bud to this stage has taken approximately 2.5 months.

I look forward to being able to harvest this fruit and will update the net stage – the stage when all the spikes have disappeared.
