I agree that it is a Gesneriad, specifically, some species/variety of Aeschynanthus, aka Lipstick Plant.

Yes, one of the images at Dave's Garden of Breynia disticha minima looks very much like the plant I have. I apologize for the mistyping of the URL. I left the 's' off of photos. I have corrected it below. Thanks so much. Here is a link that might be useful: http://www.flickr.com/photos/superelfin

Looks like Penstemon digitalis, perhaps the cultivar 'Husker Red'

No, definitely not Callistemon. It could possibly be a Protea. A bit hard to tell without more detail of the plant. Do you have any other photos of the same plant?
