It's not a pepper plant at all. Google images type in black nightshade.

Wow, two minutes apart habjolokia, so count my post as part deux!

Yikes and they're toxic to boot! Best to be rid of it then! Thanks for the feedback the_northeast_chileman and habjolokia.

NEChileman we were quick on the response but the link you included is a great source and made it easy for Bobby to identify. Bobby do you have any other pepper plants growing?

It was the multiple fruit/calyx shape that sealed it for me, pix helped!

Not at this stage but my wife and I love our peppers so we'll be eyeing to buy some more plants in the future. Being fairly new to growing pepper plants could you recommend any variety that might suit us?

Depends on how hot/mild you like them. I favor chocolate habanero and fatalli peppers in flavor. But I also like a good ghost pepper hot sauce home made. Some like Hungarian hot wax peppers most big box and nurseries carry them more mild type of pepper.
