First, I apologize for cross-posting. I posted the following message in the Houseplant Forum, but would also like to ask fellow Mainers for help in identifying a plant.

I do not have a picture of this plant that I saw at the Visitor's Center of the Pineland Farms in New Gloucester, this weekend. The leaf is in the shape of the nasturtium leaf, some as big as 6 inches in diameter. It's shiny and dark green with spots in a light yellow or lime green color. The spots are irregular in size, but as big as a nickel. The plant looks established with about 3 dozen leaves on sturdy stems. It is placed by the window with no direct sun light.

If anyone recognize this plant, please drop a note.

Thank you.
