Scarification: Soak in hot tap water, let stand in water for 24 hours
Stratification: none required
Germination: sow 1" deep, tamp the soil, mulch the seed bed
Other: fall sowing in mulched beds is often prefered to artificial strat and spring sowing|germination may be delayed until the following year
In a Nutshell:
* Brahea armata, commonly known as Mexican blue palm or blue hesper palm, is a large evergreen tree of the palm family Arecaceae, native to Baja California, Mexico. It is widely planted as an ornamental.
* It grows to a height of 15 metres (49 ft), 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.
* This species is the most widespread endemic palm of Mexico’s northern peninsula; 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 or Washingtonia robusta.
* 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.
* The Cocopah people ate the seeds after roasting them. more...
* Seed - best sown as soon as it is ripe in a warm greenhouse at not less than 24°c. Germination of fresh seed usually takes place in 3 - 4 months at 25°c. Stored seed is very slow to germinate. Pre-soaking the seed for 24 hours in warm water prior to sowing may shorten the germination time. Plants form a long tap-root some time before forming a shoot so it is best to sow 2 - 3 seeds per deep pot. Grow the seedlings on in the greenhouse for at least their first three winters. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. more...
