Carrot: Scarlet Nantes or Chandonnay (best flavour, hands down)
Beet: Detroit Dark Red, Cylindra
Chard: Rainbow, Bright Lights, Ruby Red (I can't pick just one - I love chard)
Peas: Little Marvel (picked young they're snow peas, picked older they're excellent shuckers. Very sweet and tasty.)
Cukes - Pickling: American Pickling (picked real young, you get the gherkin sized ones)
Cukes - Slicing: Lemon (unusual and less gassy than English types)
Daikon: Purple (better flavour, more spice)
Radish: Cherry Belle (super fast, heat resistant)
Lettuce - leaf type: Oaktag
Lettuce - head type: Burgundy Romaine
Lettuce - other head type: Buttercrunch
For all lettuce types, these are good high-heat performers.
Bush Beans: Royal Burgundy (best flavour hands down, and attractive purple pods that turn green when perfectly cooked.)
Pole Beans: Rattlesnake (excellent flavour, huge beans)
Field Beans: Haba Verde (fava type) - great producer.
Squash: Kombucha, Hubbard, Butternut (all for different reasons. For whatever obscure reason, I can't grow pumpkins, but Kombu come quite close. Hubs and Butters are baking squashes, winter type.)
Zucchini: Black (prolific and mold resistant)
Potato: Atahualpa (red-gold pied variety, medium wax, good baker and frier)
Tomato - grape/cherry type: Strawberry (sweet, hugely prolific)
Tomato - yellow: Golden Queen (sweet, irregular chambers, prolific, and resistant to mildew)
Tomato - red: Brandywine (a beefsteak type that really tastes like a tomato! Also great in the heat)
Tomato - purple: still in testing.
Tomato - sauce: Pomodori Guantia (Sicilian Roma type, huge fruits, super meaty, prolific plants that fruit three times even though they're determinate)
Tomato - tree: Rojo de Sangre (best for juicing and saucing, sweeter than Dorado)
Corn - sweet: Seneca (yum! Sweet and produces at altitude.)
Corn - starch: Luna Llena (white) and Luna Nueva (black) You'd call these feed corn, I think; I use them for Humitas and Tamales.
Hot pepper: Aji Amarillo, Lagrimas del Dragon
Sweet pepper: Pimiento Dulce (a roundish hybrid from down here, semihot with tons of crunch)
Banana: Limon or Rosado
The remainder of stuff I grow is very local - I doubt you're considering Naranjilla or Mashua, for example.
