Typically when you go to the grocery store, you only see imperator carrots but there are four other types available to grow.
Imperator: This type is typically longer as it can reach about 10 inches long. The carrot is tapered. An example is Cosmic Red.
Danvers: This type is resistant to cracking and grows in a cone shape that reaches up to 8 inches long. This type is also tolerant of poor soil. An example is Danvers 126.
Chantenay: This type has a 2 inch wide top that tapers down to a point like an ice cream cone. While this type will reach 6 inches long, it is great to grow in shallow or heavy soil. An example is Shin Kuroda.
Nantes: This type grows like a cylinder and is rounded at the top and bottom and will reach about 7 inches long. This type grows faster than the others but does not store as long. An example is Scarlet Nantes.
Minis: This type will grow up to 4 inches long and is a great candidate for growing indoors under grow lights or in containers outside. This type also does not store as long. Examples include Little Finger & Parisian
