I saw this plant in a botanical garden in North Carolina.
I'd appreciate help identifying it.
Thanks.

Rhodiola?

Interesting. Did you take any other pics?

Thanks for the Rhodiola suggestion, Janine. I looked up R. rosea and the foliage is quite similar but I'm entirely unfamiliar with the plant habit of Rhodiola, so I'm not sure.
Tiffany, I took only one other picture with the plant label, of course. But the label states Alyssum oxycarpum, which doesn't seem likely to be right.

Agree. Was this growing outside?

I think it isAlyssum oxycarpum.
Most of the photos online show it's blooming. But, it's dormant rosettes look exactly like that of the ones in your hpoto to me.
For example: https://nargs.org/forum/image-...

IT does seem like some species of Alyssum. I think it's the one in its tag.

Except it looks nothing like the 2 images Scott already added for Alyssum oxycarpum

I don't think the current photos are accurate?
If they were, a lot of these more alpine Alyssum can look really different when in their dormant/succulent/rosette phase than their blooming phase.

Could also be Odontarrhena obovata

Scott, you're going to have to go back when this is blooming.

photo of Alyssum oxycarpum from the link sedumzz posted. I think it looks right.

I agree that the picture sedumzz posted from NARGS looks just like my plant, so I guess I should have believed the tag. But all the images I scanned using Google Images look like the ones I posted to the Plants Database in the past. So I do think it's likely the plant looks quite different when flowering than earlier in the spring. I have a plant of Alyssum oxycarpum in my rock garden (which is where prior images came from). It's raining now, but I'll check the foliage when it dries out a little. My plant is pretty little, so I'm not sure if it will be definitive. Thanks to all of you for your help!
