Prolific PL won't stop - genetic anomaly?
I have a single Plattefoot Brandywine that I grew in a container isolated from all my other plants. It has been cranking out tomatoes for months and as of this morning when it started snowing, was still flowing and setting fruit - its almost November! All of my other plants, of every variety, have long-since succumbed to late blight, withered, and died-off. Fearing a hard freeze, I just picked the remaining green fruit off it - probably close to 4 pounds worth.
So my question - is this just what happens when a plant never catches blight? Do all tomatoes have this potential, or is this plant a genetic anomaly? Of course, I saved seeds so I can at least try to answer this question next year, but does anyone have any input or had a similar experience with a plant that just wouldn't quit?
