Looks like a Plectranthus. Perhaps a particularly silvery cultivar of P oertendahlii. But the pictures are very dark. Can you post some clearer ones?

Thank you Floral. Here are a couple more pictures, hopefully better. Do some varieties of plectranthus have rubbery leaves?

I believe it is Senecio mikanioides, often and incorrectly referred to as German ivy...Plectranthus o. may be similar, but is in the mint family and has square stems - check yours.

Yes, many Plectranthus have rubbery leaves. But check out the Senecio suggestion. I missed the blindingly obvious .... Plectranthus would have opposite foliage.

Yes!!! Thank you so much Rina and Floral, it is an exact match for S. mikanioides! Gosh, its been driving me crazy trying to figure out what exactly it is. Interestingly when you do an internet search it does show both this and the variegated German Ivy with the same name, as well as a varietal name of Magic Marble. Anyway, just so glad to have an id. Thanks again!
