The Medjool Date Palm

The Date Palm Phoenix dactylifera is a palm, extensively cultivated for its edible fruit. Due to its long history of cultivation for fruit, its exact native distribution is unknown, but the date palm probably originated somewhere in the desert oases of northern Africa, and perhaps also southwest Asia. It is a medium-sized tree, 15-25 m tall, often clumped with several trunks from a single root system, but also often growing singly. The leaves are pinnate, 3-5 m long, with spines on the petiole and about 150 leaflets; the leaflets are 30 cm long and 2 cm broad. The full span of the crown ranges from 6-10 m.

Fruit

The fruit of the Date Palm is a drupe known as a date. They are oval-cylindrical, 3-7 cm long, and 2-3 cm diameter, and when unripe, range from bright red to bright yellow in colour, depending on variety. Dates contain a single seed about 2-2.5 cm long and 6-8 mm thick. Three main Cultivar Groups of date exist; soft (e.g. 'Barhee', 'Halawy', 'Khadrawy', 'Medjool'), semi-dry (e.g. 'Dayri', 'Deglet Noor', 'Zahidi'), and dry (e.g. 'Thoory'). The type of fruit depends on the glucose, fructose and sucrose content.

Food Uses

Dry or soft dates are eaten out-of-hand, or may be seeded and stuffed with fillings such as almonds, candied orange and lemon peel, and marzipan. Dates can also be chopped and used in a range of sweet and savoury dishes, from tajines (tagines) in Morocco to puddings, bread, cakes and other dessert items. Dates are also processed into cubes, paste, spread, date syrup or "honey" called dibs, powder (date sugar), vinegar or alcohol. Recent innovations include chocolate-covered dates and products such as sparkling date juice, used in some Islamic countries as a non-alcoholic version of champagne, for special occasions and religious times such as Ramadan.

Other Uses

Date seeds are soaked and ground up for animal feed. Their oil is suitable for use in soap and cosmetic products. They can also be processed chemically as a source of oxalic acid. The seeds are also burned to make charcoal for silversmiths, and can be strung in necklaces. Date seeds are also ground and used in the manner of coffee beans, or as an additive to coffee.

Date Palm leaves are used for Palm Sunday in the Christian religion. In North Africa, they are commonly used for making huts. Mature leaves are also made into mats, screens, baskets and fans. Processed leaves can be used for insulating board. Dried leaf petioles are a source of cellulose pulp, used for walking sticks, brooms, fishing floats and fuel. Leaf sheaths are prized for their scent, and fibre from them is also used for rope, coarse cloth and large hats.
