They grow in a clay deposit in a field around my shop. The dirt has never been altered or amended. They do not grow in my limestone gravely soil or the caliche. They are a sign of a nice wet spring. They do not show their faces in droughty years. I do not water or tend to them in any way and they are fine with it other than taking the dry years off. I tried moving it and it did not take. I did move it to under some oak trees in a limestone soil and shade. I love them and want many more. I am thinking about collecting some seeds and propagating them this fall. Any ideas of how to treat the seed?
