Is this a sedum, a euphorbia or what?

Thriving in containers in a front garden in Wimbledon. Yellow flowers spring and summer. At first I thought it was Sedum kamtschaticum, so I bought a couple of specimens, but they're deciduous. These photos were taken yesterday.

I like the way it hugs the container, I would like to fill a very large container with it.

 

They do look like a form of Sedums to me Howard but I'm just guessing..Someone in the know will be along shortly to give you a better answer.

 

Cannot see detail but looks like a creeping Sedum sp.....even blowing pic up I cannot see any detail.

If it has white milky sap its a Euphorbia.
I think the leaves look pretty fleshy, so probably a sedum.

If it is deciduos why is it still in leaf?

 

Ah yes, well the devils in the sp . . . . .

I wonder if there's a specialist Sedum nursery I could contact.

 

I live not a million miles from Wimbledon and have something very similar growing in a pot on the patio, acquired as a cutting from a neighbour. It too has yellow flowers in summer. And it is evergreen, and doesn't appear to mind frost.

I don't think it is a sedum or a euphorbia, but rather some kind of relatively hardy succulent. Perhaps an echeveria - its flowers and habit of growth are certainly very similar to the echeveria prolifica in an adjacent pot. And its rosettes of leaves aren't that dissimilar, either.

I've dug out an old photo - you can see it in the top row second from the left, with the echeveria prolifica to the right of the cyclamen in the row below. (To the right of that is another succulent, Graptopetalum paraguayense.)

ETA: you can tidy it up/ propagate it very easily by breaking off straggling stalks, cutting those short, and placing the rosettes on gritty soil where they will root very readily.

 

The mystery deepens. Unfortunately it's not my garden so I can't really go and snap off a bit!

 

Knock on their door and offer a swap for some other cuttings!

 

May I suggest you knock on the door and ask if they know which one it is.
Many people can be extremely helpful when you admire a plant that they have.
They may even give you a wee bit.

Nothing ventured nothing gained

 

Just a minor problem...Sedum spurium mostly have pink flowers.
Howard Stone said yellow flowers.

Unless it happens to be Sedum spurium Green Mantle?

I have a creeping sedum which is evergreen, but it can get rather leggy and 'gappy' at this time of year. That seems to be what's happening to "Howard's" sedum. It's interesting that the one at the edge of that patio seems less affected by this, perhaps it's in lighter soil and/or getting more sun?

On the right of the OP pic there appears to be an Aloe aristata just above the green bin, so possibly someone who is experimenting with succulents outdoors.
A knock on the door would perhaps get a good response.

 

Goodness to my eyes it is just a tiny green plant...you have sharp eyes Pete!

 

Love me. Love my garden. SS!
