Zephyranthes drummondii should be fully hardy if you get the right forms from south-central Kansas. These tolerate temperatures to -20F. Sadly, I do not grow it from there. I never found it when I looked out of season while looking for other things. I do have an Arkansas form that has small, less than 3 cm flowers, but it is fragrant and seems fertile.
