Can foxtail lilies thrive in zone 10b, Southern California?

I like the look & how tall foxtail lilies (Foxtrot) are but I see they are max zone 8 or 9. Would they be able to thrive in temperatures 100+ zone 10b in dry conditions? I would use a shade cloth but summer temps would still be high.

    Where exactly in SoCal are you located? Upper USDA hardiness zone "limits" are really useless and have NO bearing on how well plants will thrive in hot climates. All they were intended to measure is average winter cold temperatures....nothing else.

    According to the Sunset Western Garden book, which should be the only guide you use for judging plant suitability in your area, Eremerus species, foxtail lilies, can be grown anywhere other than the high desert (ie., Mohave desert, Arizona, etc.) or the very mild southern coastal areas.
