Is there such thing as a 'sterile' plant?

[gssgarden]

I put in a Neves Azorian Red plant around the 15th of April. From seedling until transplant, it has looked healthy, dark green leaves, no bugs or disease. While all others are approching the 3'-4' mark in height and full of flowers and a few toms, the NAR is only about 1 1/2' tall and not one single flower. There are no signs of it getting any either. It's very dense and 'bushy'. Alot of leaves, but they really seem to be crowding the center of the plant. So much that I timmed the inside of the plant to maybe facilitate the production of flowers. But nothing. I'll trim again later with more vigor.

Is there a name for a tom that won't put out any flowers? Or is it just called 'a waste of space'?

Thanks.
