I am not good with these, but bump.

It could be one of the hardy sedum groundcovers, but maybe I is etiolated? Most of them have much tighter grow habit. Has it ever bloomed for you?

Sedum japonicum 'Tokyo Sun'

Chris

That looks like it...but as I said, it is more compact than op's plant. And not hardy, but still etiolated. Nice plant, good color...

Thank you rina and Chris! According to wiki: "Sedum japonicum 'Tokyo Sun': Tiny bright yellow gold succulent foliage. Most yellow in full sun, more lime green in shade. Low growing mounding habit. Good ground cover and in rock and miniature gardens. Not as cold hardy as most sedums. Can be grown indoors with very bright light."

Im not sure if it is etiolated as i gave it plenty of bright light, but ever since I got it a month ago, it has not bloomed yet.

It probably wants more sun; if you look at the photo of it on net, it is more compact - almost no bare stem space between the leaves. I am sure you give it best light available, but indoor light is usually not strong enough, it looses some intensity coming thru the glass, and drops considerably moving even slightly away from the window.

If you can put it outside, it will start growing more compact, and when ready - bloom. If you do so, acclimatize it to outdoors light to prevent burning.

You didn't say where you live, but it will overwinter outside if at least z8 or higher.
