Date trees typically reach about 21–23 metres (69–75 ft) in height, growing singly or forming a clump with several stems from a single root system. Date fruits (dates) are oval-cylindrical, 3–7 cm (1.2–2.8 in) long, and about an inch (2.5 cm) in diameter, ranging from bright red to bright yellow in color, depending on variety. They are very sweet, containing about 75 percent of sugar when dried.
