I'm not clever enough to recognise it, I'm afraid, Kathy, (Though I'm sure there will be someone who can) but if you can keep it alive, come springtime you should be able to take cuttings and root them, and then you will have several plants of exactly the same kind. It's a beautiful colour.
Welcome to GoY, by the way!

Beaten to it..Like Gattina says take cuttings, they take very easily.

And Welcome from me too!

Welcome from me to .Enjoy the pleasure for now then take tip cuttings in Spring.

its a pelargonium I think one of the 'pastel' group. The plug plants had that name. I had this one a couple of years ago.They are easy to take cuttings from .

welcoe to GoY

Very difficult to put a name to it, but I can tell you that its a single flower zonal pelargonium.
I seem to think that it just one of the new annual pelargoniums that comes out every year from the garden centre's.
It would be interesting to know how you came by it,but like the comments from other growers, keep it going through the winter, and take some cuttings when springtime arrives.
