They sure do look the same. I think you're right, vngarden. After looking it over a bit, it does look more like Stromanthe sanguinea 'Tricolor' http://davesgarden.com/guides/pf/go/59470/ based on the difference in the foliage grey-bands that I only noticed in Ctenanthe but not in the pic above.
Thanks for that, It might be Stromanthe based on the pictures, but looking at the specifications of the plant, it's definetly higher than 45 cm like Stromanthe, it's more like 90-100 cm wich would rather point on Ctenanthe, what do You think?
If Stromanthe is being sold as a household plant at Home Depot or Lowe's, then it is likely not going to be as tall as if it was growing in its native or natural habitat. The Stromanthe "tricolor" that I photographed at Volunteer Park Conservatory in Seattle, WA is around 4-5ft tall.
I do agree that the more common one in the trade is likely to be a species of Stromanthe, at least in the United States.
