Bugs Bunny was an expert. He was always chewing on a carrot, Daucus carota, and rudely talking with his mouth full. Because carrots can be stored in refrigeration for a few months, Bugs Bunny could get one whenever he wanted to. However, in home gardens, they are cool season vegetables that are grown through spring and autumn, but not through summer or the middle part of winter.
Carrots are biennial. They complete their life cycle in two seasons. They are vegetative during their first season, as they produce their edible and elongated conical taproot. If not harvested, they bloom and go to seed in their second season. By then, their fat roots are tough and useless. Carrots are ready for harvest in three to four months after their seed are sown, depending on variety.
Carrots are famously bright orange. Yellow, white, red, purple and black varieties have been gaining popularity in the past many years. The longest carrots might be a foot and a half long, but most are less than half as long. Many are only about four inches long, or less. They may be as narrow as half an inch, or wider than two inches! Some carrots are more uniformly cylindrical than conical.
