I like the idea of a fig hedge! I'm planing one myself, but not on the property line. Don't want the neighbor's stealing MY figs! I'm thinking of planting fast growing tree cuttings, letting them grow 2 or 3 years, and grafting their cut branches onto their trunks to make the cross boards for the fence, braiding them across, and then whacking them off at about 5' tall with a good dose of stump killer. So a living fence with no post holes should result from that, until the fence is big enough to hold before it grows no more.
I plan to plant prickly pears against that fence for 3 reasons: 1) To keep out critters and fence climbing humans. 2) The pads taste like green beans/asparagus, and are a nice vegetable year round. 3) The cactus pear is delicious fruit.
To answer your question, I went by the rave's of fig fanatics to decide which varieties of figs to plant. They were right on VdB. It will take time for the newer figs in my collection to give me their taste test!
