I've grown this little blue sedum for a few years now, but never known it's name. It growing next to Angelina in this photo and seems to be marginally hardy in zone 5b . This one made it through the winter but often it doesn't but reseeds easily. The flowers are white.

Sedum pallidum var. bithynicum?
Sedum hispanicum?

I think Sedum pallidum var. bithynicum is exact right. It says hardy to zone 6 which explains why it doesn't always make it through my winters and also that it has almost no roots which explains why it grows so well on my path which is just pea gravel over landscape cloth. Thanks for finding the answer for me. It is one of my favorite sedums.

Here is a photo of S. pallidum var. bithynicum in bloom. See if the blooms match when yours flowers. http://www.sedumphotos.net/v/s...
Great photo of a happy sedum.

The flowers sure look like I remember the, but I'll take a photo to compare this summer.

Look forward to seeing the updated photos.
I have trouble identifying some of the sedum, Celene's suggestions are very good.

Stilldew, I haven't seen that sedum in person yet, but I've seen several photos of it! It is a pretty one!

My little sedum is starting to bloom and the flowers do match S. pallidum var. bithynicum. Thanks for helping me with the ID.

Susan, they are beautiful. Great close-up photo.

I agree that is pretty!
