Yellow carrots are varieties that are grown specifically to yield sweeter flavor at maturity while also retaining healthy texture; ie: the taproot is not woody or fiberous. There are at least three known types of carrots: Imperator, Danvers and Nantes. Yellow carrots are Nantes type varieties, having both round shoulders and a blunt non-tapered tip. They have a firm and crunchy texture and an earthy sweet flavor with notes of celery and parsley.
Yellow carrots are available year-round.
Yellow carrots belong to the Umbelliferae family along with parsnips, fennel caraway, cumin and dill. The Umbelliferae family is a cosmopolitan family comprising 455 genera and over 3500 species, which makes this family one of the largest taxon among higher plants. Each plant in this family has the umbrella-like flower clusters at maturity that distinguishes this family of plants. Carrots are the most important food crop within the Umbelliferae family. They are classified as a root vegetable, though the plant is comprised of a root, midribs and greens and is entirely edible.
In nature, different strains of carrots contain varying types and amounts of carotenoids, the pigments responsible for orange, yellow, and red colors. Yellow carrots contain high levels of the cartenoid lutein, a pigment similar to beta-carotene that is absorbed as Vitamin A in the body.
