Hi Lyle,

Thanks for a most interesting question. A web search indicates “Fireball” was developed in the 1950s by the Harris Seed Company of New York. The University of Minnesota developed “Early Fireball” in the 1960s by irradiating “Fireball” seeds.

Here’s a page about the U of M development:

I couldn’t find “Early Fireball” for sale online, but a web search indicates several seed companies sell “Fireball” seeds. It’s considered an heirloom plant. If you want to grow this tomato, you probably need to buy seeds and start plants yourself.

If you haven’t grown tomatoes from seed before, it’s not difficult. Here’s some information:

I hope this helps! Good luck!
