Thanks for the acorn! Always happy when someone enjoys learning from one of my posts!
"Epinasty" is not a word in the usual gardening dictionaries, so not commonly known. I learned it in a plant physiology course.
This seems to be a common response by tomatoes to waterlogged roots. The grower apparently had several varieties which responded this way under the specific repotting conditions here. I think the sample size is too small to worry about carrying forward an undesirable trait unless the plants continue to develop epinasty when growing outdoors with better drainage.
But, everyone is free to do as they like in their own backyard!
