My favorite are the short-season carrots (usually called "nantes-type" carrots). Since we're northfacing, and at a higher elevation, and surrounded by trees, I find it really helps to have fast-growing carrots...otherwise they just don't gain any size before they lose sunlight!

So brittle and delicate, in fact, that it has to be hand dug, as it cannot withstand mechanical harvesting. Enjoy Mokum as a baby carrot or as a full-size 6-8 inch tasty treat. Very rich in vitamin A and high in sugars. Striking orange roots with contrasting thick dark green tops. It's still the finest fresh-eating carrot we know. Nantes type. MA. IR: Ad, Ar, P.

Among the earliest of our spring-sown carrots, the 7-8 inch, bright orange roots have a fine texture and a mild, juicy crunch. Plants have tall, strong tops for easy harvest and produce uniform, smooth, cylindrical carrots with narrow shoulders. MA. IR: Ad, Ar, C, P.
Though, I gotta say, the most delicious carrot I ever had was one from Joseph Lofthouse's carrot seeds.

Due to heavy limestone-derived lake-bottom soil I select mostly for Dantes and half-Nantes types which can be harvested whole without breaking, and generally grow without lots of knobs and multiple tap-roots. I select stress tolerant biennial plants to produce the seed crop.
Here's my son with the carrot he grew! This carrot was super delicious, and we enjoyed every single bite!
