Dave do you grow it? I have tried it several times and I don't ever recall harvesting any. They always rot. They have put me off of growing heirlooms.
Does Kelloggs Breakfast need the Texas heat? I am in zone 10 so we are very moderate in temperature.
How much separation do you need for the seeds to come true? I usually grow one 25' long bed of different tomatoes.
I always like to try some new tomato every year. Maybe it's time to try an heirloom again.
