Orange (Citrus sinensis) - Description
The orange (specifically, the sweet orange) is the fruit of the citrus species Citrus×sinensis in the family Rutaceae. The fruit of the Citrus sinensis is called sweet orange to distinguish it from that of the Citrus aurantium, the bitter orange. The orange is a hybrid, possibly between pomelo (Citrus maxima) and mandarin (Citrus reticulata), cultivated since ancient times.
Orange (Citrus sinensis) - Blooming
Produces fragrant white flowers followed by ovoid, yellow, or orange fruit. Fruits may take around 1 year to mature. Bloom times vary among species.
Orange (Citrus sinensis) - Growth
Evergreen trees and shrubs. There are many different varieties of citrus, such as, grapefruits, lemons, limes, limequats, mandarin oranges (tangerines), oranges, etc.; however, they all need heat and need to be hardy plants in order to prosper. Citrus can be grown in places where the temperature does not fall below 20°F. Otherwise, grow Citrus in a cool greenhouse with a minimum temperature of 35°F (2°C). During the day, set temperatures between 41-50°F (5-10°C), and at night, keep the temperature at 36°F (2°C).
Orange (Citrus sinensis) - Planting

Citrus is susceptible to aphids, mites, scale insects, and mealybugs.
Orange (Citrus sinensis) - Interesting facts
Legend has it that ancient Grecians assumed certain foods had special qualities. One such legend suggests that oranges and other Citrus warmed the body, and therefore should be eaten in the morning to get the body moving. It is because of this belief that orange juice, grapefruits and other Citrus are such popular breakfast foods/drinks.
Orange (Citrus sinensis) - Soil and irrigation
Citrus trees require moist soil, but the soil needs to have fast drainage. Newly planted trees should be watered twice a week while established trees should be watered every other week.Often times Citrus fruits will start dropping as a result of high heat and low humidity. This is sometimes unavoidable, but is exacerbated by very dry soil. If you have extensive fruit drop (especially in summer), be sure that the soil is moist.
