Steve, I don't know the answer to your question about the distinctions between Zephyranthes atamasco and Z. simpsonii. But you post prompted me to tell an atamasco lily story. Last weekend I had the chance to visit a famous garden in northern North Carolina. About a half hour north of our destination, as we sailed down the two lane road at 55 mph, I let out a whoop: I thought I had seen atamasco lilies blooming by the roadside. Because we had a scheduled appointment with our host, my companions were reluctant to stop. As we got farther and farther away from the site, I began to doubt what I had seen. The flowers seemed a bit big for Zephyranthes atamasco, at least as I had known it. Our host, who grows an amazing array of plants very well, surprised my by not having Z. atamasco - although several other Zephyranthes were present in the garden. On the return trip I keep my eyes peeled for the roadside plants. Luckily we found them. As we approached the site, I had a growing sense that I was about to be disappointed: maybe what I saw were plastic Easter lilies someone had put out on the lawn. But no, they were atamasco lilies, really big, shapely, beautiful atamasco lilies. The fragrance was wonderful. It was a windy day, and some of the plants had assumed a posture which made it easy to see why so many people call this the Easter lily. I've posted a photo of these plants (the ones which were doing the Easter lily imitation) to the wiki: http://pacificbulbsociety.org/pbswiki/files/… co_jmck_01.jpg.JPG Those of you who know this genus well may be able to answer a question for me. My impression is that Z. atamasco has the largest flowers of the genus. Is that true?
