Origin
Juliet, bred by Known-You Seed, won an All-America Selections award in 1999 and has been the default grape tomato for home gardens since. It is enormously productive, the oblong fruit hold on the vine and in the bowl without splitting, and it carries intermediate resistance to both early and late blight. The flavour is good rather than exceptional, which is a fair trade for how little goes wrong with it.
