I need help identifying this plant. I used to be very active with all things growing, and could name anything. My life has taken a different direction and so I am rusty. My son has sent me a picture of something he's growing, and my pride keeps me from admitting I am not sure of what plant it is. Any help from anyone will be greatly appreciated, as soon as you can! Thanks so much for "saving" me.

I couldn't get the photo to paste into this document, but will attemtp to describe it. It has an arching type of stem, with one leave on each stem. It looks tropical, like maybe a tropical type. It has solid edges, no serated edges, and slightly heart shaped. it is solid green on edges w/ pink in the middle.

I know that's a terrible description, but the best I can do.

Thanks for any help,

Terry
