I have no clues as to what it is but I don't for one minute think it's a succulent as they have thickened, fleshy, water holding leaves/stems/caudexes that store water in times of drought. From what I can see, your plant has none of these features and looks more grass like.

It looks very like Armeria maritima gone to seed or with the buds damped off. It does like extremely dry situations, but I don't think qualifies as a succulent, as Gill says.

I don't think it is armeria; I had that plant too but didn't last too long. The flowerhead was yellowish, not dry or gone to seed. I didn't keep any notes about it since it was disappointing - it was sold here (Toronto, Canada) as 'novelty' plant...

Not a succulent, but a bog plant. Appears to be Syngonanthus flavidulus (Michx.) Ruhl. aka Yellow Hat Pins or S. chrysanthus.
This photo appears staged for a magazine, so one must sadly assume the fate of the plants wasn't important since they only exist in bogs, not in your living room.

You are right; I found a tag, it was sold here only as 'Mikado'.
