I have a little experience with several summer-growing clones of various unnamed rain lilies. Our summer is very hot by most people's standards, and rain occurs, but is not frequent. Habranthus tubispathus blooms, even in smallish containers, in late summer, when we have the first few cooling nights. I have not tried this in the ground. Every flower sets seed. It is more or less evergreen here, but I keep it in the shade. Plus, the containers I use are tall and narrow, so they don't dry out as fast as would short, squat containers. A large pink-flowered plant with maroon undersides to the straplike leaves grows and multiplies just fine in the ground in full sun if it gets some water. It blooms with each summer rain, but not necessarily with each watering. In a container, even 1 gallon or larger, it often goes dormant for the entire summer. Its leaves emerge when the first cool nights occur and it blooms sporadically some time after. Its tunics are dark brown, whether wet or dry. It has never set seed, even after hand-pollination with another rain lily. Two narrow-leaved rain lilies bought years (decades?) ago remain unidentified since avian or canine garden assistants removed many unsightly labels. Both have white flowers. Both have tan tunics. Both are dormant all summer in 1-gallon or slightly larger containers, emerging in the fall. I have not tried these in the ground. Neither has set seed, but then I have not tried hand pollination. One has near-cylindric, grassy, bright green leaves of small diameter that stand upright, like tall grass. I suspect it is Z. candida. It is in full fresh foliage with buds, and had we not had 2 solid days' worth of rain they might have opened today. I will try and take a picture if it opens tomorrow. The other has wider, grayish-green, straplike leaves that relax over the container edge. I suspect it may be Z. drummondii. This one is emerging but is not as far along as the other. It may be I am just not able to keep them wet enough in these containers, and they would perform better in the ground, as does the large-flowered pink one. Leo Martin Phoenix Arizona USA
