Nona up close!

I googled and found out that Custard Apples are of the Annonaceae family ~ Annona reticulata. Its flower has 3 thick petals that are light green on the outside, probably fused with the sepals, and light yellow on the inside.

This flower is in early stage as can be seen by the smaller centre and the stamens still look fresh.





This stamens of this one in later stage of bloom have dried up and fallen off.
