Returns Simplified.Brahea armata, commonly known as the Mexican Blue Palm or Blue Hesper Palm, is one of the most striking and ornamental hardy palms, celebrated for its dramatic silvery-blue foliage and elegant, architectural form. Native to the dry canyons and deserts of Baja California in Mexico, this palm is exceptionally drought-tolerant and ideal for Mediterranean or desert-style gardens.
Foliage: Large, rigid, fan-shaped leaves with a stunning blue-grey to silver-blue colour, each leaf reaching up to 1.5 metres across. The striking colour stands out beautifully against darker greens or gravel planting schemes.
Trunk: Develops a sturdy, solitary grey trunk up to 3040 cm thick, often covered with fibrous leaf bases when young, which become cleaner and more rugged as the palm matures.
Flowers & Fruit: Mature palms produce spectacular arching sprays of small creamy-white flowers that can extend beyond the canopy by up to 5 metres, followed by small round fruits.
Height: In its native habitat can reach 1215 metres, but in cultivation (especially in cooler climates) often grows to around 68 metres over many decades, with a slow, steady growth rate.
Because of its unique colour and tough nature, Brahea armata is frequently planted as a feature palm, either as a lone specimen or in gravel gardens, rockeries and modern architectural landscapes.
Thrives in full sun, which is essential to develop its best blue-silver colouring.
Ideally placed in an open, sunny position where it can be viewed from all sides to appreciate its symmetrical form.
One of the hardiest blue palms, tolerating temperatures down to around -8C once mature.
Young plants are more tender and should be protected from hard frosts, especially when temperatures drop below -4C.
In colder regions, may be grown in large pots and moved to a cold greenhouse or protected spot in winter.
Very drought-tolerant once established, thanks to its desert origins.
Water regularly during the first 23 growing seasons to help establish deep roots, then reduce.
Allow the soil to dry between watering it dislikes being waterlogged.
Prefers well-drained, sandy or gravelly soils.
Tolerates poor, rocky ground but must have excellent drainage to prevent root rot.
Avoid heavy clay or consistently wet areas.
Requires minimal feeding.
In pots or very poor soils, feed in spring and mid-summer with a slow-release balanced fertiliser or a specialist palm feed.
Very low maintenance.
Remove old, fully brown fronds close to the trunk for a neat appearance.
Avoid cutting green fronds, which the palm still relies on for photosynthesis.
Generally very robust and rarely troubled by pests or diseases.
In damp climates, may be susceptible to fungal problems if planted in poorly drained soil.
Excellent in large pots, particularly for patios or sunny courtyards.
Use a free-draining, gritty compost, such as cactus compost mixed with additional horticultural grit.
Ensure pots have drainage holes and are raised on feet to allow excess water to escape.
Water sparingly in winter.
