up to tall.
Most of the taproot consists of a pulpy outer cortex ( phloem) and an inner core ( xylem). High-quality carrots have a large proportion of cortex compared to core. Although a completely xylem-free carrot is not possible, some cultivars have small and deeply pigmented cores; the taproot can appear to lack a core when the colour of the cortex and core are similar in intensity. Taproots are typically long and conical, although cylindrical and nearly-spherical cultivars are available. The root diameter can range from to as much as at the widest part. The root length ranges from , although most are between .
Flower development begins when the flat meristem changes from producing leaves to an uplifted, conical meristem capable of producing stem elongation and a cluster of flowers. The cluster is a compound

. The stamens of the brown, male, sterile flowers degenerate and shrivel before the flower fully opens. In the other type of male sterile flower, the stamens are replaced by petals, and these petals do not fall off. A nectar-containing disc is present on the upper surface of the carpels.
Flowers change sex in their development, so the stamens release their pollen before the stigma of the same flower is receptive. The arrangement is centripetal, meaning the oldest flowers are near the edge and the youngest flowers are in the center. Flowers usually first open at the outer edge of the primary umbel, followed about a week later on the secondary umbels, and then in subsequent weeks in higher-order umbels.
The usual flowering period of individual umbels is 7 to 10 days, so a plant can be in the process of flowering for 30–50 days. The distinctive umbels and floral

Cultivation
Carrots are grown from seed and can take up to four months (120 days) to mature, but most cultivars mature within 70 to 80 days under the right conditions. They grow best in full sun but tolerate some shade. The optimum temperature is . The ideal soil is deep, loose and well-drained, sandy or loamy, with a pH of 6.3 to 6.8.
Fertilizer should be applied according to soil type because the crop requires low levels of nitrogen, moderate phosphate and high potash. Rich or rocky soils should be avoided, as these will cause the roots to become hairy and/or misshapen. Irrigation is applied when needed to keep the soil moist. After sprouting, the crop is eventually thinned to a spacing of and weeded to prevent competition beneath the soil.

s in these cultivars.
Western carrot cultivars are commonly classified by their root shape. The four general types are:
* Chantenay carrots. Although the roots are shorter than other cultivars, they have vigorous foliage and greater girth, being broad in the shoulders and tapering towards a blunt, rounded tip. They store well, have a pale-coloured core and are mostly used for processing. Cultivars include 'Carson Hybrid' and 'Red Cored Chantenay'.
* Danvers carrots. These have strong foliage and the roots are longer than Chantenay types, and they have a conical shape with a well-defined shoulder, tapering to a point. They are somewhat shorter than Imperator cultivars, but more tolerant of heavy soil conditions. Danvers cultivars store well and are used both fresh and for processing. They were developed in 1871 in

. Cultivars include 'Danvers Half Long' and 'Danvers 126'.
* Imperator carrots. This cultivar has vigorous foliage, is of high sugar content, and has long and slender roots, tapering to a pointed tip. Imperator types are the most widely cultivated by commercial growers. Cultivars include 'Imperator 58' and 'Sugarsnax Hybrid'.
* Nantes carrots. These have sparse foliage, are cylindrical, short with a more blunt tip than Imperator types, and attain high yields in a range of conditions. The skin is easily damaged and the core is deeply pigmented. They are brittle, high in sugar and store less well than other types. Cultivars include 'Nelson Hybrid', 'Scarlet Nantes' and 'Sweetness Hybrid'.
Carrot breeding programs have developed new cultivars to have dense amounts of chemically-stable acylated pigments, such as
anthocyanin

Storage
Carrots can be stored for several months in the refrigerator or over winter in a moist, cool place. For long term storage, unwashed carrots can be placed in a bucket between layers of sand, a 50/50 mix of sand and wood shavings, or in soil. A temperature range of and 98% humidity is best. During storage, carrots may be subject to the development of bitterness, white blush, and browning, leading to carrot losses. Bitterness can be prevented by storage in well-ventilated rooms with low
