What a lovely surprise! I had a similar experience with something like it with a Black Madeira cutting last year... I forgot about it, and left it in a pot with dirt... and actually, did not even "try to root it". I left it there, and forgot about it. A few weeks later.... WOW. I had a rooted BM and it had leaves on it. That was an awesome fig moment... More success than when I actually tried rooting LOL
By The way, I LOVE the Hollier figs I rooted this year. By far the most vigorous and prolific growers of all rooted types. It did not matter, what size, medium and where I root, I had 100% success with this type. I have not had an opportunity to taste the fig. Can't wait!!
