The discussion has shown how important it is to find out how different species in a genus grow, and not treat them all the same because we think they are related somehow. My relatives in mild southern California have the same last name I do, but they don't live the way I do in hot Phoenix. Recall genus Habranthus is often called "zephyranthes" and both are called "rain lilies" by gardeners because both genera have tubular flowers, often after rain falls. Habranthus flowers point up at an angle while Zephyranthes flowers point straight up. There are winter-growing Habranthus and Zephyranthes, and summer-growing Habranthus and Zephyranthes. Habranthus tubispathus is a grassy-leaved, yellow-flowering plant that blooms in the fall (now for me.) I have a Zephyranthes that may be something called La Bufarosa that is dormant all summer in a container here even with regular watering, then grows and blooms now that nights are cooling. It has narrowly strap-shaped leaves that are maroon underneath. It is common in landscapes around here and often available at the Desert Botanical Garden plant sales. Leo Martin Phoenix Arizona USA
