Since this relates to Desert King, I'm reopening this rather than starting a new thread.
About 7 years ago, my dad planted a fig tree in his yard [he lives about 8 miles from Jon], but the fruit has never ripened. We surmised that the tree [an unknown transplanted from the home of a friend who was moving], needed more heat than coastal San Diego could supply.
So, two years ago we bought a Desert King from Jon and planted it in his yard.
Well....this year, he not only got ripe Desert King figs, the other tree has produced ripe figs too. This, despite San Diego having a cooler-than-average summer this year.
Dad said "I think the other tree realized that unless it put out, it was about to be replaced,"
Some pics of the unknown tree, taken about 2 years ago:
