It is a German Striped Tomato, heirloom. Because it was love and meant to be, I then came across an article in Dave's Garden newsletter on how to save heirloom tomato seeds. The author made it sound so easy that I said, "Hey, I can do this!" And you can, too. The best part about saving the seed is that you can still eat the tomato – and delicious it was. (I sliced it up and ate it on some sprouted bread with homemade cream cheese and a dash of salt and pepper.)
The first thing to do is to scoop out the seeds, along with the gel, into a jar.
Then add some water, about 1/2 cup. Store somewhere where the smell does not offend you, because it will smell. In about a week, a whitish/gray mold will form over the top. This is what you want. You are fermenting the seeds to weed out the bad and discourage disease. (According to the article I read, if you are trading tomato seed it is proper etiquette to ferment your seeds.) If you have a weak stomach, don't look below. Eeeewwww!
Now, carefully scrape off the moldy film. I used a little spoon. Add a little water to the jar and stir. Good seeds sink. Bad seeds and any remaining pulpy gel will float. Keep stirring and carefully pouring off the water until all you have left is clean seed. Then strain the seed through a coffee filter or other material, and spread them out to let dry for a full day or two.
The seeds are now ready to store. I store my seeds in a little box.
I cannot wait to plant these in my garden. Hopefully, I've done this right and I will be slicing up baseball-sized German Striped Tomatoes next summer! I should also be able to save more seed and share.
If you cannot get your hands on a German Striped Tomato, but would like to grow them in your garden next season, Johnny's offers the seed.
