Date palm
A slow-growing palm cultivated for its sweet, edible dates.
Phoenix dactylifera, commonly known as the date palm, is a flowering-plant species in the palm family Arecaceae, native to the region from the Gulf States, though the Lower Indus Valley is considered an area of early cultivation rather than part of its original native range. It is cultivated for its edible sweet fruit called dates and is widely grown across northern Africa, the Middle East, Australia, South and Southeast Asia, Portugal, Spain, coastal Mediterranean basin, and the desert regions of Southern California. The species is naturalised in many tropical and subtropical regions worldwide and is the type species of genus Phoenix, which contains 12–19 species of wild date palms.

Lore & Background
Date palms reach up to 30 metres in height, growing singly or in clumps with several stems from a single root system. They are slow-growing and can reach over 100 years of age when maintained properly. The leaves are 4–6 m long, with spines on the petiole, and pinnate with about 150 leaflets. The date palm is dioecious, having separate male and female plants, with sex determination through an XY system. Only 50% of seedlings are female and fruit-bearing, so commercial plantations use cuttings of heavily cropping cultivars.
Dates are naturally wind-pollinated, but in traditional oasis horticulture and modern commercial orchards, they are entirely hand-pollinated. One male can pollinate up to 100 females. Manual pollination is done by skilled labourers on ladders or by wind machine. In some areas, such as Iraq, the pollinator climbs the tree using a special climbing tool. The fruit are oval-cylindrical, 3–7 cm long, and 2–3 cm diameter, ranging from bright red to bright yellow when ripe, depending on variety. Three main cultivar groups exist: soft (e.g., Medjool), semi-dry (e.g., Deglet Nour), and dry (e.g., Thoory).
There is archaeological evidence of date cultivation in Arabia since the 6th millennium BCE. Dates are emblematic of oasis agriculture and highly symbolic in Christian and Jewish religions. A draft genome of P. dactylifera (Khalas variety) was published in 2011, followed by more complete assemblies in 2013 and 2019. The species name dactylifera is Latin, meaning 'date-bearing', from Greek daktylos meaning 'date' or 'finger'.
Reader's Guide
The date palm holds profound significance as a staple crop in arid and semi-arid regions, providing a nutritious fruit rich in sugar. Its cultivation spans millennia, with archaeological evidence from the 6th millennium BCE in Arabia and from Neolithic sites in western Pakistan around 7000 BCE. The tree is central to oasis agriculture and carries symbolic weight in Christian and Jewish traditions. Its ability to thrive in harsh conditions and produce fruit for over a century makes it a vital resource for food security and economic livelihood in the Middle East, North Africa, and beyond. The species has been introduced to the Americas, including California and Mexico, and its cultivars such as Medjool and Deglet Nour are now grown in the southwestern United States. The date palm's genome has been sequenced, enabling mapping of genes for fruit color and sugar content. Pests like the red palm beetle and dubas bug threaten production, while hand-pollination remains common. The Judean date palm, from seeds about 2,000 years old, has been successfully sprouted, demonstrating remarkable seed longevity. The date palm's legacy is one of resilience, adaptation, and deep cultural roots across civilizations.
