I could answer this better later in the season when more buds come out. And I could answer it much better next year after I've left more limbs exposed to air through winter. Currently, I don't know that I've lost any varieties that I cut back to within a few inches or a foot of the ground and them mulched under, using mostly unchopped fall leaves. (The problem there of course is who wants to chop off most of their fig tree or bush every year? Which is sort of like killing the patient to save it.) Herman2 has mentioned somewhere recently which of his fully exposed and much taller varieties came through a similar tough winter well.
It still seems to me that many of the Mount Etna figs seem to be the hardiest figs around. And I've been a little surprised at the end of this winter by the apparent hardiness of Celeste and Brunswick too.
If I had more resources and space, in this growing zone, I would be tempted to grow all figs in-ground horizontally one or two feet above the ground, in rows, then mulch those rows 2 or 3 feet deep, pushing back the mulch after winter to flank the figs through spring/summer/fall then prune and cover again. No tarp, no tying. (Maybe the unchopped fall leaves as mulch acted as a sort of tarp to the figs this past winter.) The only fig I put a big plastic tub over this winter, a rodent decided it made an excellent house and ate the bark off the base of the bush. The tree is coming back from the base, but no other bush sustained rodent bark damage which I merely mulched and did not house.
I expect and hope that well positioned Mount Etna cultivars at least several feet tall and several years old will come through most winters here with minimal damage.
As I posted elsewhere: ongoing tentative compilation of Mount Etna or Mount Etna type figs, below. I don't remotely have all of these cultivars but these are the types that I would expect to be the mainstays in this cold growing zone. Frost last night deadened a few early spring fig leaves here.
Malta Black, Takoma Violet, Dark Portuguese, Marseilles Black, Sal's EL/GS, Salem Dark, Black Bethlehem, Gino's, Unknown #11, Jersey Fig, Martini, Don Fortissi Black, Hardy Chicago, Keddie, English Brown Turkey, Hardy Pittsburgh, Macool?, Rosetta?, Owensboro?, Hardy Cleveland?, Hardy Hartford, GM #11 (Sicilian Dark), Abba, Ginoso? Roundhill? ...
(update: Herman2, who has much more experience with figs than I do, notes: Malta Black,and English Brown Turkey are not MT Etna Type! Malta B,has three lobes leaves,and English BT,has large redish fruits when ripe,and different leaves. Also English BT needs longer Summer to ripe. Malta Black is a better tasting fig compared to all others,and the only common with the others is that is early ripening.)
