I am in full agreement with what Harvey is saying.
Although my place being a fig Paradise, we occasionally go through short periods of under 0ºC (32ºF) temps in winter mostly, as well as the typical, more or less frequent frosts not lasting too long.
Never, never consecutive days in freezing temperatures...morning rising sun soon to warm up rapidly
Snow being totally absent
Capri figs do OK in such environment.
Lived in Algeria for several years and during winter, their world known fine fig country (Kabylie) may go through much, much colder and snowy winters 600/700 meter altitude, and still they grow mostly Smyrna figs and selected local Caprifigs.
BTW - early 1900's , Eisens/Roeding,, time, California received various strains of Caprifigs from that same Kabylie, their genes may still be around
Biggest threat for these figs are the (not so rare these days) dangerous peak's of high temperatures- heat waves- in April and/or May when fragile larvae have to take for 1,2 or 3 days in a row, temperatures as high as 37 or 38ºC (close to 100ºF) . When this happens, fully exposed small trees will loose practically all Profichis
Bigger trees with more protection from their size and mass of shading leaves will produce a fraction of their usual crop.
Had a look on Gene's Central Arkansas climate numbers and IMO it would not be difficult to set the wild fig in there. (he questioned that on another topic)
