Hi Lynn,
The history of what we can call the "Brandywine" category is complex, convoluted and riddled with errors, myth, and lore. It is still getting sorted out but what we do know is that regardless of what you read on most seed sites, the original 'Brandywine' tomato was regular leaf, red fruited and released by Johnson and Stokes in 1889.
For whatever reason, the name is now associated with many different varieties, probably for marketing reasons. There are pinks, yellow, black, etc.
To compound things, several years back, the primary commercial grower of tomato seeds for most of the garden seed companies, mixed up their stock. It was a mess and some seed companies, I suppose in an effort to save face, simply changed their descriptions! That is how red, potato leaf "Brandywine" appeared.
Since we raise our tomato seeds, we didn't get caught up in all that drama. The 'Brandywine' that we offer is red and regular leaf. We do also carry pink, 'Sudduth Strain' and yellow.
Best,
Mike
