Thanks for the reply.
I bought this as a very small seedling which was labelled ghost pepper. First time growing ( what I thought was a ghost), so not familiar with them. The plant is only about 10 in. tall and has 9 of these peppers on it. The one shown has to be 2 months old and is not changing at all in colour. I posted some pics of the flower under the help identify category...if that helps. Thanks again
