detailed seed-starting info below

Native to the US southwest. Reportedly has good fall color.
So far, after several years in our garden, they appear to be most like a smaller version of A. illustris, with similar willowy and shiny leaves, and flowers held at the tips of the stems. Ours are vase-shaped, about two feet tall – taller than the 10-14" I found in online references, but not as wide around. I'm not so sure what we have is the real thing – in online photos, A. jonesii tends to have chubbier petals, whereas the ones on our plant are quite slender. In any case, our plant was starting to outgrow its space, so I decided to edit it out of the landscape, in favor of some smaller-growing plants.
