Description edit

Growing to 12–20 m (39–66 ft) tall, Trachycarpus fortunei is a single-stemmed fan palm. The diameter of the trunk is up to 15–30 cm (6–12 in). Its texture is very rough, with the persistent leaf bases clasping the stem as layers of coarse fibrous material. The leaves have long petioles which are bare except for two rows of small spines, terminating in a rounded fan of numerous leaflets. Each leaf is 140–190 cm (4 ft 7 in – 6 ft 3 in) long, with the petiole 60–100 cm (2 ft 0 in – 3 ft 3 in) long, and the leaflets up to 90 cm (2 ft 11 in) long. It is a somewhat variable plant, especially as regards its general appearance; and some specimens are to be seen with leaf segments having straight and others having drooping tips.[3]

The flowers are yellow (male) and greenish (female), about 2–4 mm (3⁄32–5⁄32 in) across, borne in large branched panicles up to 1 m (3 ft 3 in) long in spring; it is dioecious, with male and female flowers produced on separate trees. The fruit is a yellow to blue-black, reniform (kidney-shaped) drupe 10–12 mm (13⁄32–15⁄32 in) long, ripening in mid-autumn.[4][5]

Distribution and habitat edit

This plant has been cultivated in China and Japan for thousands of years. This makes tracking its natural range difficult. It is believed to originate in central China (Hubei southwards), southern Japan (Kyushu), south to northern Myanmar and northern India, growing at altitudes of 100–2,400 m (328–7,874 ft).[1][4][6][7]

Due to its widespread use as an ornamental plant, the palm has become naturalised in southern regions of Switzerland, and has become an invasive species of concern.[8]

Windmill palm is one of the hardiest palms. It tolerates cool, moist summers as well as cold winters, as it grows at much higher altitudes than other species, up to 2,400 m (7,874 ft) in the mountains of southern China. However, it is not the northernmost naturally occurring palm in the world, as European fan palm (Chamaerops humilis) grows further north in the Mediterranean.[5]

Uses edit

Trachycarpus fortunei has been cultivated in China and Japan for thousands of years, for its coarse but very strong leaf sheath fibre, used for making rope, sacks, and other coarse cloth where great strength is important. The extent of this cultivation means that the exact natural range of the species is uncertain.[4][5]

Cultivation edit

 
The approximate range of cultivation in the US with little to no winter protection

Trachycarpus fortunei is cultivated as a trunking palm in gardens and parks throughout the world in warm temperate and subtropical climates. Its tolerance of cool summers and cold winters makes it valued by palm enthusiasts, landscape designers and gardeners. It is grown successfully in cool climates such as the UK, France, Belgium, The Netherlands, western Poland as well as southern and western Germany. In the UK it has gained the Royal Horticultural Society's Award of Garden Merit.[5][9]

In North America, mature specimens can be found growing in the coastal areas of the Pacific Northwest, the upper southern states, and Mid-Atlantic states. Commonly lower tolerance limits of −15 to −20 °C (5 to −4 °F) are cited for mature plants.[10] Young plants are less hardy, and can be damaged by only −8 °C (18 °F). Individuals of the T. f. 'Nainital' subspecies have lived outside in the northern Connecticut town of Woodbury.[11] continuously since the early 2000s with protection, where some winters have reached −21 °C (−6 °F).[citation needed] et al., 2016 found one healthy specimen in Plovdiv, Bulgaria, which has survived a low temperature of -17 F/-27 C.[12][13]

The cultivar group Trachycarpus fortunei 'Wagnerianus' is a small-leafed semi-dwarf variant of the species selected in cultivation in China and Japan. It differs in rarely growing to more than 5 m (16 ft) tall, with leaflets less than 45 cm (1 ft 6 in) long; the short stature and small leaves give it greater tolerance of wind exposure.[5] It has often been treated as a separate species T. wagnerianus in popular works, but is now included within T. fortunei.[1][4][7]

As Food edit

The young flower buds are cooked and eaten in a variety of ways.[14]

Nomenclature edit

The species was brought from Japan (Dejima) to Europe by the German physician Philipp Franz von Siebold in 1830. The common name refers to Chusan Island (now Zhoushan Island), where Robert Fortune first saw cultivated specimens. In 1849, Fortune smuggled plants from China to the Kew Horticultural Gardens and the Royal garden of Prince Albert of the United Kingdom.[15] It was later named Trachycarpus fortunei, after him. It was first described by Carl Friedrich Philipp von Martius in 1850 in his Historia Naturalis Palmarum but under the illegitimate name of Chamaerops excelsa.

The names Chamaerops excelsus and Trachycarpus excelsus have occasionally been misapplied to Trachycarpus fortunei; these are correctly synonyms of Rhapis excelsa, with the confusion arising due to a misunderstanding of Japanese vernacular names.[10]
