I like the unknowns a lot too. I have a few, but none of these. At this time I have way too many fig trees. I would love to grow more, but my wife is about ready to kick me out. She does not care for figs at all. Luckily the raspberries and peaches I grow keep here happy, and the 25 fig trees can stay for now!
The unknowns in my collection I like are Unknown Teramo. It produces small figs that start out amber, and if you let them sit on the tree wrinkle and become red inside. Taste is very figgy, I like this one, and produces and grows well. Craven's Craving is a Black Madeira type fig from Portugal. It is not BM. It is a little too late fruiting for here. I can only harvest about 1/3 of crop. Excellent figs though. I want a Black Madeira type that ripens earlier here. I have a new candidate just added. JF&E Black Madeira Not! Sold as a BM, but many say it fruits too early to be BM, so hoping this one fits the niche I'm trying to fill. It is a twig this year. Hoping it survives our cold winters. It has to make it in the garage for me to grow it. Other unknowns I have are Unk Sheepshead, and Sweet Dianna.
