Funky Friday Flowers

When I went to the Post Office earlier in the week I saw this funky flower and just had to take a photo of it. Doesn't it look like something from the "Little Shop of Horrors" It is almost as tall as I am and about a foot across on the top. I asked the Post Office lady what kind of flower it was, and she told me, AND I wrote it down and then, of course, lost the paper. It has a resemblance to a poinsettia on steroids but it wasn't!
