Hi JD. Congratulations, and I am certain that this is just the beginning of great success with your fig orchard.
We should have our first Strawberry Verte next season hopefully, but it's rooted well and growing strong this season.
While I of course defer to my colleagues with far more experience on the general question of how age of the tree affects flavor, I can tell you that our LSU Purple (about 8 years total in ground) just gets better every year. It's gone from good the first few years, to outstanding, with the sweetness and flavor dramatically improving this year especially. I've gone from enjoying the LSU Purples, to great excitement in picking every single one. It has been very productive this year, and yet with our family of 5 not one LSU Purple is going to waste. They are becoming that good! I hope it will be the same with all your figs, including this Strawberry Verte, that it will get better every year.
In just the few years I have been growing figs it is becoming obvious that there are great variations in flavor even from the same tree, depending on many factors including heat, rain, age of the tree, sunlight, soil quality, and no doubt many other factors as well.
Best wishes.
