Hi Plant Wizard, thank you for your response. I suppose they could be Calla Lilies, but they don't have the traditional wavy kind of edge on the leaves nor any spots that I am used to seeing. I guess those are just one variety. Anyway, thanks so much- I'm excited now because these are pretty hefty, hearty plants in pots! Time will tell I guess. I'll come back and let you know if they bloom.

Your "I should have names this post Name this Yellow Flower!" flower is sideways. But it looks like a yellow loosestrife, Lysimachia punctata. Your "Perfect Yellow Flower" flower looks rather like an Inula sp. but I can't see the leaves to be sure. Your "I found this beautifull plant on Vancouver Island and in Community Gardens in Calgary, AB" flower looks like leopards bane, Doronicum orientale to me. Numbering your photos would help us to note which plant we are talking about. FataMorgana

Looks like a gymnocalicium to me.

Difference between nighttime and daytime temps shouldn't be problem; even 20's is pretty warm (I am assuming that is C). My daytimes are in 30'ties C, and nights drop to 12*C sometimes - I wouldn't mind if that was every night! :) Cooler nights are actually pretty good for plants. I am north of Toronto, On, and weather is quite similar to yours in Montreal. Pls. do not use sand for potted succulents regarding what you read on some 'blogs'. Yes, it could be used for some, but only if you really know your plants. It is best if you just don't use it. Grit is great addition or pumice; but if you don't have (or not easy available), use lots of coarse perlite. If you mix perlite 50/50 with the Cactus & Succulent soil, that will be quite an improvement. If you can, keep plants outside. But make sure you acclimatize it very slowly, since it is very etiolated and most like very weak. You need to get it into better light and water properly - sparsely is not proper for succulents. If you pot it into well draining mix, you can water thoroughly when needed. Pot seems to be very large for your plant. I would repot it into smaller pot. Etiolated plant will not 'revert' even if you give it much better conditions. If my plant, I would trim/prune it extensively. If you want some ideas, pls. ask. BTW, here is Cacti and Succulents Forum if you are interested to read more about succulents...
