(80 days) Determinate. We know that this is a very old English greenhouse variety whose developer had great expectations! This tomato is a workhorse - it's prolific, producing heavy crops of deep red, perfectly round, 4-5 oz. tomatoes over a short period of time. The fruits have a rich tomato taste and it can also handle most weather conditions, which is sure to be a benefit, given our strange weather seasons over the last few years.
