There are three droughtland species that should perform very well with you: Zephyranthes longifolia, Habranthus concolor and H. inmaculatus, all three winter dormant. H. inmaculatus is a fabulous plant with cork screw broad grey leaves somewhat resembling a tazetta (more properly, Narcissus tortifolius) and very large white flowers. Stunning. H. concolor has sulphur yellow flowers and broad greyish foliage. z. longifolia has long arching narrow leaves and smallish yellow flowers.
