For many years, one of my primary sources of information about tomatoes was Tatianas Tomato Base. My other primary source was Dr. Carolyn Male, Tatiana stopped maintaining her web based knowledge base in 2018. For the heck of it, I clicked on http://tatianastomatobase.com/wiki/Category:B.C_KO_T. The page is still active and usable although it hasn't been updated since 2018. Many users of this site have probably not been around long enough to know about this source.

I haven't grown Kelloggs Breakfast or it's potato leaf sister in many years. I remember both as exceptional tomatoes in all respects with only the leaf shape serving as a difference. I actually always thought KBX was a slightly better tomato but many would argue that point. My KBX seeds are too old to still be viable and I want to grow them again next year. I don't want to gamble with old seeds so I was searching for some fresh seed when I checked Tatianias knowing it was too old to furnish new information.

I hope Tatiana's tomato base will help some new gardeners looking for some old information they may have been searching for.

Tatiana's is a wealth of information and is my 'go to' site. We have a very nice thread here: resources-to-look-up-tomato-variety-info-t3101.html that lists some great resources to find information on varieties of tomatoes. Tatiana worked so hard for many years on her Tomatobase, it's a shame that nobody is helping to keep it up to date. Her database was the place to go and no where else could beat it. Well done Tatiana!
