What a great experiment. I found the way you presented the cutting diagrams to be very helpful, especially when I see the results 6 weeks later. Great presentation. I look forward to seeing more of your experiments in the future.
I have had some similar results with palmerii, it is a slow grower for me also. And I can't seem to keep Ogon alive. It seems to need just the right conditions to stay healthy and happy. It does seem to want more shade and moisture than most of the other sedum. There are nice colonies of it growing in the shade at the Oregon State Hospital Cremains Memorial in Salem. It is lovely to see when happy.
