I'm with tabby on the Sedum seiboldii. The one on left appears to be correct. Can you give us a better photo of the one on the right?
Sedum 'Chocolate Drop' I am finding this one stays upright if given enough sun, it also seems to have deeper color in full sun. Or it might just loose the deep chocolate color as the summer progresses. This is my first complete year with it, so I'll have to pay more attention next year to keep track of the color changes. Think I'll plant some in full sun and some in partial shade to see.
Spring I love your S. 'Thundercloud'. Think I will have to get that one next spring.
I had not heard of the Party series until you posted it here. Thanks so much.
Here is a link to the complete Party series.

I love their leaves in all three of the series, really love what they say about the growth habit.
Found some interesting history on S. 'Samuel Oliphant'.

From another site:
Kindly note that as this plant grows and matures an occasional newly sprouted section may not carry the special coloration. If this occurs you can simply remove that part of the plant at the crown level.
**This plant is so special that it is protected by a plant patent. Only qualified growers are permitted to offer it. Asexual reproduction is strictly prohibited.**
Boy did I learn a lot this morning. Thank you so much Spring.
