Description
The blue fan palm grows to a height of 15 metres (49 ft),[5] with a stout trunk. Its distinctly bluish leaves are 1–2 metres (3 ft 3 in – 6 ft 7 in) wide, with 1-metre (3 ft 3 in) long petioles. The leaves are persistent in nature, forming a shag around the trunk; in cultivation they are typically burned or cut off. The inflorescences extend out beyond the crown, reaching 5 metres (16 ft) in length. The flowers themselves are small, appearing in February and March, while the fruits are 18–24 millimetres (0.71–0.94 in) in length, brown and with a generally ovoid to globose shape.
Taxonomy
Distribution and habitat
This species is endemic to the Mexican state of Baja California, distributed from just 8 miles south of the international border near the Jacumba Mountains, to the central desert and Isla Angel de la Guarda. Plants growing in the Sierra de San Francisco in Baja California Sur may be of a different species.[6] It is locally common in arroyos and canyon bottoms, and has been observed growing in rock crevices at higher elevations. It is sometimes found with Washingtonia filifera var. filifera or Washingtonia filifera var. robusta.
Ecology
Uses
Brahea armata has an attractive appearance, especially when young, and is commonly available at nurseries in the American southwest and in warm temperate locations elsewhere. In the UK it has gained the Royal Horticultural Society's Award of Garden Merit.[7] It is drought tolerant (although occasional deep irrigation is recommended), can handle both partial shade and full sun, and temperatures down to −10 °C (14 °F). It is found under a variety of names, including "Mexican blue palm", "blue hesper palm", "big blue hesper palm", "blue fan palm", "sweet brahea", and "palma blanca".
The Cocopah people ate the seeds after roasting them.
