Dangerous Palms – Dave’s Garden

When most individuals consider palms, they consider a ferny-like tropical tree or shrub, kind of like what Xena Princess Warrior would expertise operating by way of on her present filmed in New Zealand, or the gentle, willowy foliage the troops of some jungle conflict film could be slinking by way of. Certainly, many individuals develop palms for his or her luxurious tropical foliage. Nonetheless, quite a lot of palms are usually not so ‘user-friendly’ and will be harmful in a number of methods.

Many palms, notably those that develop effectively for me in California, are outfitted with all kinds of sharp, annoying spines, thorns, enamel or just very sharp leaves. These palms are usually not solely unsafe to go blundering into, however will be dangerous pruning or planting.

Examples of palms with spines are many, although most critically spiny palms are actually tropical in nature and I should not have any of those in my yard. A few of these palms are primarily spiny when younger, presumably to offer them some protection towards predation whereas nonetheless sufficiently small to be thought of meals, and shedding the spines at maturity when, as timber, are much less fascinating to herbivores. Nonetheless, different palms are so spiny, even in maturity as to have spines on practically each floor and construction. These palms are inclined to have essentially the most vicious spines and will actually be averted, or planted removed from walkways.

Zombia antillarum has a extremely decorative spiny woven sample on its a number of trunks (decrease picture above). These spines are very sharp and thick

ImageImage

Some species are merely spiny throughout… above is a leaf and spathe from Acrocomia aculeata that’s utterly coated in spines; proper are fruits of Astrocaryum alatum which are spiny- this whole plant, together with the leaflets, have lethal sharp spines

ImageImage

Among the most lovely however harmful palms within the tropics are of the genus Pigafetta (left picture), as they not solely have very lengthy, very sharp spines arming their leaves (see fallen leaf base on proper), however they develop rapidly to sixty toes tall or extra, after which drop these lethal, spiny leaves, impaling whoever occurs to be unfortunate sufficient to be under on the time. These leaves can weigh over thirty kilos, too.

Many palms have enamel on the petioles (the ‘department’ that holds the leaf), and a few of these enamel can actually take a chunk out of you if you’re not cautious. The frequent Washingtonia (Mexican Fan Palm) is well-known for being a tough palm to not solely trim safely, however the falling leaves are inclined to get held on ones clothes or drop onto others under inflicting critical injury.

Chamaerops humilis is one other frequent palm with killer enamel alongside the petioles. Trimmed palms look nice and are true panorama specimens (proper)… to trim the palm on the left to get to the palm on the suitable will be a particularly harmful and painful enterprise

ImageImageImage

ImageImage

most Copernicia have sharp teeth- Copernicia baileyana (left) as do most Livistona sp. (Livistona saribus in proper picture)

Nonetheless different palms have modified leaves alongside the bottom of the petioles that may be extraordinarily sharp and lengthy making pruning these palms a very hazardous expertise. Phoenix palms are a main instance of such harmful crops.

Image

Calamus caryotoides, like many Rattan Palms, have whips and cirri which are modified leaflets used for climbing (these are climbing palms and climb up different vegetation within the jungle). These cirri are lengthy, skinny and closely armed with extraordinarily sharp hooks that are inclined to seize onto what ever walks by too shut. It’s a beautiful palm, however a very harmful one to plant wherever close to a pathway.

Different palms have toothless petioles, however that doesn’t all the time imply there may be nothing harmful about them. The petiolar blades themselves will be sharp as knives pn some fan palms and one nonetheless must be cautious when trimming these species, or notably if one is silly sufficient to attempt to climb one.

And even the leaves themselves will be deadly on some species- with ideas so sharp who wants enamel or spines?

ImageImage

So if being punctured or lacerated just isn’t sufficient of a hazard, different palms will be harmful because of gravity. Among the bigger species can drop leaves that weigh over fifty kilos every. A mature Royal Palm (Roystonea species) can let free a 60 pound frond that may not solely ship a nasty blow, however do a substantial amount of critical property injury to no matter it crushes under. Even the frequent King Palm can unleash a twenty pound frond from time to time that may at the very least give on a decent bruise.

Since this picture was taken, the proprietor offered the palm and had it moved for the reason that fronds had broken a number of autos parked under. Left reveals a row of Roystonea oleraceas alongside a mall parking space in Hawaii, however no parking allowed close to these palms

Royal and King palms in zoo (left) removed from the place they falling leaves can knock somebody within the head… hope the flamingos are paying consideration. Proper reveals one other very tall species with extraordinarily heavy leaves: Ceroxylon ventricosum. Thankfully these leaves are inclined to fall straight down, with the leaf base hugging the trunk the entire means down, so this one is a bit much less hazardous to have alongside a sidewalk or driveway

Coconut palms are well-known for his or her heavy, strong fruits being harmful to pedestrians and cars under, and lots of tropical inhabitants have been badly injured by these heavy, coconut-milk-filled bombs. Borassus and Loedicia species have respectable gravity-propelled weaponry as effectively.

Should you dwell within the Seychelle Islands, strolling under the palms will be much more hazardous as that’s the residence of Lodoicea, the Double Coconut, aptly named because of the huge seed these palms make. Picture on proper is of a unadorned seed weighing over fifty kilos earlier than it was hollowed out. This can be a uncommon and laborious to develop species and every seed can run as a lot as $450 US.

And if you’re not satisfied {that a} falling palm leaf or seed can injure you, what of a falling palm? Although in lots of instances palms are a lot much less more likely to come down in excessive winds than most different timber, some palms cannot solely be blown over, however appear to easily fall over for no motive, even on a peaceful day. Caryotas, for no matter motive, have a tendency to do that, and although not generally grown in yards all through the world, nonetheless handle to inflict main property injury to people who do favor these species, because of their extremely strong woody trunks and top-heavy leafy crowns.

Although palms, normally, are amongst among the least poisonous of the tropical foliage crops in cultivation, some have poisonous fruits. Caryotas and Arenga species have oxylates within the fleshy coating surrounding their seeds that not solely are poisonous, however may cause bodily ache if dealt with carelessly, because the oxylates trigger a stinging sensation.

Areca catechu, aka Betel Nut Palm, has fruits generally munched on by native residents in and close to Thailand. This fruit is reasonably poisonous in that it’s a delicate stimulant however can have an addictive property. Sucking on Betel Nuts can injury enamel and gums over time, to not point out completely staining these tissues orange.

ImageImage

Notice: Cycas species (eg ‘Sago Palms’) are NOT palms, however are cycads. They’re certainly extraordinarily toxic, however I’ve not included cycads on this dialogue as a result of they don’t seem to be palms, regardless of their frequent identify)

And although most are usually not toxic, some palms drop huge quantities of seeds that may create different minor hazards, from a rotting, slippery mush, or a ball-bearing-covered sidewalk, to potential indigestible overseas our bodies in pets and youngsters, who typically eat the fruits and carelessly swallow the laborious seeds inside entire. I’ve personally eliminated a number of Queen palm seed intestinal blockages from pets through the years.

Fruits eaten by pets or kids can result in intestinal blockages as their seeds are sometimes too giant to cross by way of the center (Wodyetia left). Proper fruits are of Butia capitata and are very tasty, so consuming them could be very tempting

Addtional risks of palms may embrace harboring disease-carrying pests. Washingtonia palms are well-known for being a big residence advanced for all kinds of vermin from rats and mice, spiders and scorpions and all kinds of birds (pigeons and owls mostly, although owls are hardly ever thought of pests).

ImageImageImage

Washingtonia robustas with full skirts most likely full fo all kinds of surprises… this is the reason most publically planted palms are trimmed repeatedly

Final, however not least is the doable hazard of seeing a palm so lovely one merely drops useless in amazement…
