Jim: We planted extensive haemanthus hardiness trials last year. So far, the only species that is up is H. montanus. Our winter only dropped to 12 degrees F. last winter. Most are not up at this time, but are fine including H. humilis ssp. hirsutus. H. albiflos was a loss in all locations ad was H. deformis. I will know more as they continue to resprout..hopefully.
