Gardeners' Notes:

Positive Hamptongrows On Mar 24, 2013, Hamptongrows from Hampton, VA wrote:

We grew about 15 plants and they were good producers. Not as tasty fresh as I'd hoped, but once dehydrated, the flavor was really intense. I'll grow them again this year for "sun-dried" tomatoes for next winter.

I would have called this the Halloween Tomato. The top half is dark inky purple, nearly black. The bottom half is deep orange. The flavor is only so-so, but it is interesting.

the first commercially available real purple tomato within the united states. it was obtained in 2004 through the crossing of a wild peruvian purple tomato with a regular red variety at the oregon state university by Jim Myers. there is still great diversity in coloration, size, shape, texture, flavor, and all growth habits. it is being stabilized and hybridized by many breeders including Tom Wagner, the man responsible for the quality variety green zebra. the tomato is more often than not in fact a red tomato, with a skin that turns darker than crayon purple once exposed to sunlight, much like a tomatillo.
