Succulent ID (reminds me of broader-leaf Sedum pachyphytum)

[amanzed]

Hi, I bought this blue-green, glaucous pretty from Shelley at Worldwide Exotics in Sylmar, CA, nine days ago. She wasn't sure of the ID. Does anyone have suggestions? It reminds me of Sedum pachyphytum, but with larger overall form and broader leaves.

Or could it be some kind of Pachyphytum or Graptopetalum?

Thanks so much for the advice!

I've seen this growing in a fairly large bed at the Huntington on the far South side of the Desert Garden, but could not find an ID plate (I think it may have been covered by the robust growth of this plant.) Did not see any flowers. I'm going for a hybrid form of Sedum pachyphytum.

Great looking plant!
I'm going to venture and guess Pachyphytum Longifolium.

Hi!

Any more ideas on the ID of this stonecrop?

The season has proceeded and this handsome, easy, friendly plant has flowered. The flower looks a lot like Graptopetalum or X Graptosedum to me. But I'm not good at excluding, say, Sedum or other intergeneric hybrids like X Graptoveria.

Tangentially, when you get down to it, some argue that all of Graptopetalum should be lumped into Sedum. In fact, apparently all of Graptopetalum seems to fall within Linnaeus's original -- rather general -- description for Sedum. I think stonecrop taxonomy is due for a major overhaul in the next 20 years.

I posted my photos at International Crassulaceae Network Forum and the moderator on the Identification forum, Margrit Bischofberger, gave me the ID for this plant:

Sedum allantoides

Very quickly, too!

However, if you Google images of Sedum allantoides there seems to be a consensus as to what it looks like and though similar, its leaves appear more cylindrical, whereas yours seems a bit less so and a bit flattened.

There is a flat leave form of allantoides and some of the HBG ones appear sort of intermediate. My sense, though, is the flower is distinctive among Sedum.
