A while back I went to the plant swap hosted by Washington Gardener and DC Urban Gardeners. I got a tomato start from a young woman who had brought many different varieties in little pots. Several of the pots had lost their labels, and she wasn’t sure which variety mine was, but thought it was probably a black krim, which is a big purplish heirloom variety. But now that the plant has gotten bigger and started to produce fruit, it’s clearly not a black krim:
What type of tomato is this? They’re about twice as big as a typical cherry tomato, but slightly smaller than Romas or San Marzanos. And I can’t tell whether they’re ripe now as yellow tomatoes, or whether they’ll turn red. Does anyone recognize this tomato? Are they ready to pick? Help!
Gradually Greener 
It’s a yellow pear of some sort, those are pretty much ripe. There are a bunch of different varieties, some are teardrop shaped like these and others have more of lightbulb or even an extreme sphere + cylinder shape — the kids at the Bloomington, IN, farmers market used to call them the bong tomatoes. You see them in teh yuppiemarts sometimes, they look fun in salads and red sauces but they’re kind of mild for cooking and once you slice them they have that white-green, unripe look of a lot of yellow tomatoes.
My grandma used to call them “Tommy Toes”, but I doubt that is the official name. LOL!
Amelia – glad that you came to the plant swap and that you got a great healthy tomato out of it. I’d gues generic Yellow Pear myself. But you might want to put a link on the Washington Gardener and DCUCG discussion lists and see if one of the swap attendees recognizes their donation.
Aloha….I lost the tag on this tomato, but have a plant that’s prolific in a large pot on my deck….I’ve been picking the yellow tomatoes because they fall off the stem easily…and they are delicious.
The tag that came with it is long lost in the soil of a 15-gal pot.
I use a very well composted soil, mixed with chicken manure and use 888 w/Magnesium organic fertilizer on a monthly basis and they’re pumping! Those seasoned landscaper/gardeners here in Kona, Hawai’i like to call it “Tokyo Turds.”….It’s a nitro-humus mixed with molasses for a pleasant smell….The finest fertilizer I know, and I’ve been in the business here for over 34 years!……..Aloha……DR.D.
