Sorry, I forgot to remove the germination part of the subject line last time.. Thanks, Jane, I really like some of those wild colours. The only species that is in my immediate area according to maps in Flora of Alberta.The caveats are: the maps are tiny dots representing the confirmed reports of each species- hard to be sure where some of those dots really are when the whole province is one inch high- unless you had seen the actual lists of locations, you'd probably get to know the patterns. My immediate are is all private land- farming/grazing of varying intensity (from intense to zero on various pieces of land) so we have a good representation of native plants, but I wonder how much official botanising has actually been done right around here-probably more so in gov't land in the foothills to the west, and along several river valleys- 30-60 km away one way or another, so I have found a number of species that don't appear right here on the map, but do show in locations that might be 30-60 or more km away in various directions. *So*, C lutescens appears some distance ( I have not knowingly seen any of the other species to be able to recognise them) to the south-east- which presumably is into a more aspen-parkland/grassland zone, C occidentalis is off to the west in the foothills or mountains, C rhexifolia also off to the west, seemingly a bit farther yet into the mountains. No mention of sulphurea except that occidentalis (which is said to intergrade with rhexifolia) at lower elevations is treated as sulphurea, though 'in our area they intergrade completely' not sure if that means sulphurea intergrades completely with occidentalis or if they mean one of these intergrades with rhexifolia... In any case, I think lutescens and occidentalis would be the* likeliest *players besides miniata, but I haven't yet studied the characters I'd need to distinguish them beyond obvious bract colours...
