Thanks for the ID. Somehow I had convinced myself last spring, when it bloomed, that it was NOT S. litardieri (which indeed I grew from seed a few years prior), but I don't remember now why.
Not sure I understand the directions for ensuring my photos show up upright. My modus operandi with any photos I take is to first correct orientation and save (my software doesn't automatically do that). After that, I do any cropping/resizing with the re-oriented picture. Seems to me that, if the ATP software wants to auto-fix orientation (and sometimes gets it wrong), there should be a way to correct it (or choose if the auto-fix should be applied) at time of uploading.
