(Phoenix canariensis var. porphyrococca) Canary Island Date Palm

Phoenix canariensis is a species of flowering plant in the palm family Arecaceae, native to the Canary Islands. It is a relative of Phoenix dactylifera, the true date palm. It is the natural symbol of the Canary Islands, together with the canary Serinus canaria. Mature P. canariensis are often used in ornamental landscaping and are collected and transplanted to their new planting location. A Canary Island Date Palm with 10 m (30 ft) of trunk is approximately 60 years of age.

Description
Phoenix canariensis is a large solitary palm, 10–20 m (33–66 ft) tall, occasionally growing to 40 m (131 ft). The leaves are pinnate, 4–6 m (13–20 ft) long, with 80–100 leaflets on each side of the central rachis. The fruit is an oval, yellow to orange drupe 2 cm (0.79 in) long and 1 cm (0.39 in) in diameter and containing a single large seed; the fruit pulp is edible but too thin to be worth eating.

Names
Common names in English include Canary Island date palm and pineapple palm. The common name in Spanish-speaking countries and in the Canary Islands is palmera canaria.

Cultivation
The Canary Island date palm is typically cultivated in wet-winter or Mediterranean climates, but also in wet-summer or humid subtropicalclimates like eastern Australia and the southeastern United States. There are even several instances of cultivated Canary Island Date Palms in high-latitude oceanic climates, such as Ireland, the UK, and the Channel Islands.It can be cultivated where temperatures rarely fall below −10 or −12 °C (14 or 10 °F) for extended periods, although it will require some protection if cold periods are longer than normal. It is a slowly growing tree, exclusively propagated by seed.

The palm is easily recognized through its crown of leaves and trunk characteristics. It is not uncommon to see Canary Island date palms pruned and trimmed to enhance the appearance.When pruned, the bottom of the crown, also called the nut, appears to have a pineapple shape.

The Canary Island date palm is susceptible to Fusarium wilt, a fungal disease commonly transmitted through contaminated seed, soil, and pruning tools. Spread of the disease can be reduced when pruning tools are disinfected before use on this palm. 

It has gained the Royal Horticultural Society's Award of Garden Merit. 

Other uses
In the Canary Islands, the sap of this date palm is used to make palm syrup. La Gomera is where most of the sap is produced in the Canary Islands.

Invasiveness
In some areas, Phoenix canariensis has proven to be an invasive plant. In Bermuda and the United States (Florida and California) it is considered naturalised (lives wild in a region where it is not indigenous). It has also spread in some areas of peninsular Spain, Portugal, Italy, Australia, and New Zealand. It is listed as invasive in California.In Auckland, New Zealand, the palm has itself become a host for the naturalised Australian strangler fig, Ficus macrophylla.
