Cole has trialed quite a few determinates so he may have some top picks.
You won't find many that are not red. But that's what breeding is for, eh.
If I was in your climate I'd try some of the Italian material - Sicilianu had some varieties listed at SSE as I recall for dry cultivation. I haven't grown many Italians but favorably impressed with foliage health as well as fruit qualities in that end of the gene pool. Determinates too.
