Brahea armata is a particularly enticing palm endemic to the Baja Peninsula. A real desert native, it tolerates excessive warmth and dryness together with important chilly, making it a good selection for harsh desert locales the place many different palms will not carry out properly. They’re pretty slow-growing and huge vegetation of 50 toes/15 meters tall could be properly over 100 years previous.
Mexican blue fan palm (Brahea armata) is distributed within the central and northern elements of the Baja California peninsula, from about San Ignacio to inside about 15 miles of the US border. Essentially the most well-known stands are most likely these … learn extra
Also called blue hesper palm, Brahea armata tends to outlive greatest the place there may be water inside a number of meters of the floor. In my second picture, this mixed-age stand is rising alongside the Arroyo La Bocana simply south of Catavina close to Santa Inez.
In my third picture, the juvenile blue fan palms about 6 toes (2 meters) tall develop within the floodplain of Arroyo la Bocana whereas the white granite hills are studded with grand examples of boojum tree (Fouquieria columnaris) and cardon (Pachycereus pringlei), amongst many different desert vegetation. The reddish hills within the distance are volcanic basalt. This advanced geology most likely performs a task in why there may be floor water on this a part of the arroyo, and why a lot of the remaining has a shallow water desk.
In my 4th picture, the pair of heavily-fruiting Brahea armata rising to virtually 60 toes tall (18 meters) is within the background. The blackened trunks point out that the useless leaf shag of those palms was set aflame sooner or later previously, maybe many years in the past, because the one on the correct has managed to regenerate portion of it. Happily fireplace doesn’t kill most of those desert kind fan palms, and as soon as charred they most likely will not be burned once more since now the remaining leaf shag is just too far above folks’s attain. And that it’s individuals who burned them..
The prolonged flowering spikes that reach far previous the leaf crown are prone to be an adaptation in direction of facilitating wind pollination for these timber, that are continuously remoted from one-another. Lengthy floral spikes that may freely distribute their pollen to the wind will perhaps have a greater likelihood of fertilizing a receptive feminine flower at a long way than spikes hidden throughout the leaves. Birds and mammals favor the fruits, which do not have a lot flesh however are nonetheless eaten rapidly as soon as ripe.
The glaucous blue coloration of Brahea armata leaves makes it a strikingly good-looking plant and really worthy of backyard and panorama cultivation. Bluish-leaved vegetation are frequent in arid and semiarid areas. Typically brought on by a layer of wax, it inhibits water loss by way of transpiration, and the pale coloration displays away among the potent desert daylight, thereby preserving leaf floor temperatures cooler and lessening cell injury or demise.
The useless leaves are persistent and will cling alongside the trunk for many years. That is additionally adaptive for the palms, as a result of it protects the trunk from temperature extremes. Nonetheless it’s an “enticing nuisance” for people wielding lighters and matches, who typically set the leaf skirts ablaze for a quick however dramatic torch-like show. Whereas this does hurt the palms, it’s lucky that the majority handle to outlive and develop new leaf crowns from the apical meristem on the prime of the trunk.
