Quite compact ie small but very productive in that it has many tomatoes even now in early June (it had no tomatoes when I purchased it):

UPDATE (September 5th)

This singleton plant grew to a height of 1 foot and about 1 foot wide (in a container). It was covered in flowers in June and tomatoes quickly formed. Possibly by....the end of July....it no longer produced any more flowers. I kept track of the yield and it gave 200 tomatoes.

Thanks for letting us know :).

That sounds rather disappointing that it didn't live very long.

I have good luck with Maglia Rosa which I grow in a 3-gallon container on the deck. It tastes very good and usually keeps going from very early in the season until frost. (I think I'm Cdn 6b).
