From my fig research activities in South Louisiana:

FYI,

O'Rourke....recently ate the first one from my own tree. It is a very good tasting fig. Drum roll please........O'Rourke IS NOT the same fig as LSU Improved Celeste. Let me repeat that again. O'Rourke is not the same as LSU Improved Celeste. I have LSU Improved Celeste trees from two sources and have studied many fig trees in other fruit orchards. The leaves on LSU Improve Celeste are single lobed and tri-lobed leaves. Never have I seen a five lobed leaf on either of my two IC trees. O'Rourke, on the other hand, has three to five lobed leaves.

You can read more about the fruiting characteristics of some of the other figs that I am studying in this link.
