It looks like the first mention of oblate (not heart) shape appears in 1996 when Chuck Wyatt offered it in the SSE Yearbook, his seed was from Southern Exposure Seed Exchange .
Then in 1998 Neil Lockhart echoes the description saying 'globes', his seed is also from Southern Exposure Seed Exchange . Pretty much after that most of the SSE listings are referring to it as 'globes' or not giving any shape description at all.
Now, that's interesting... I am growing Jefferson Giant this year, my seed came in a trade, and originally they were obtained from Neil Lockhart around 2005. Only 1 seed germinated, so I do not have lots of plants to compare, but the baby tomatoes I am seeing on this plant are certainly heart-shaped.
In 2007 SSE Yearbook another SSE member mentions heart shape, seeds from Chuck Wyatt!
Which gives two possibilities:
- Southern Exposure Seed Exchange offered seed of Jefferson Giant that were either mixed up or crossed - that's why Chuck and Neil observed globes, and not hearts.
- Chuck's and Neil's description were erroneous, and they actually had hearts not globes.
In the 2010 SSE Yearbook there is only 1 listing, that of Neil and he describes it as globes. Southern Exposure Seed Exchange does not offer this tomato anymore.
