In this case the fruit is tomatoes.
The darker ones are called Black Krim. The red/green variety are Mortgage Lifter. Both are very tasty, and have more flesh than those from the grocery store.Others in the house would likely be just as happy if I grew a couple of the beefsteak variety.
I grew both the BK and ML from seeds gathered last year. It is time to decide if I want to have them again next year. It isn't difficult to harvest a couple of packets of seeds from a tomato or two. It might be a good idea. Just in case.
