2015 Good production, didn't mind the heat. Much the same observations as last observed. Good fruit set, but did seem to slow slightly in 28C+ days. Approx 5.25 lb/plant.
2009 4-7oz brown pear shaped fruit, often has green shoulders. Not the best black tomato ever, but still very good flavour. Prolific producer, plant grew to about 3.5-4ft. Did not seem to mind the heat, but it was partly shaded for a few hours of the day by a bigger tomato. (Observed in Nelson, BC)
