Euphorbia pulcherrima
Years ago , when I worked in a flora glasshouse , I was n’t crazy about take care of the poinsettias at Christmastime .
I found them to be a turn ill-tempered , and was always worried about breaking their seemingly slight farewell off the theme while I water .
My intuitive feeling of slim gall towards them changed though , when my boss told me to foot one out to take home – the first Mexican flameleaf I would care for as my own .
African milk tree, a member of the spurge family.
And in the 10 since , my perspective on poinsettias has truly change .
They ’ve earned my respect , and I ’ve come to see them not as finical , fussy flora but as meridian model of the beauty of biodiversity .

In fact , in some way , poinsettias are quite resilient . Their unknown growth substance abuse , with its flow of sparse - look quiescency , serves as a respectable reminder that just because things might look big now , that does n’t mean a new period of vitality and beauty is n’t just around the corner .
Beyond such metaphysical meditations , poinsettias quite literally brighten up the dark wintertime months spent indoors .
Poinsettias are among the most colorful plants you may grow indoors , and although we lean to consider them chiefly to be a ( perhaps disposable ) part of the holiday interior decoration , it ’s important to commend that they arealiveand call for caretaking , just like other houseplants .
I ’m going to allow for you with a guide to care for your poinsettia , and I ’ll tell you about some of the interesting quirk in its natural story .
Here ’s what I ’ll cover :
What You’ll Learn
What Are Poinsettias?
Poinsettia , pronounced “ poyn - set - electrical engineering - uh , ” or just as commonly , “ poyn - readiness - uh , ” is a democratic vacation plant , used in particular to adorn during the Christmas time of year .
You ’d belike recognise this winter bloomer , which goes by the scientific nameEuphorbia pulcherrima , after just a quick coup d’oeil – they seem to be just about everywhere during the holidays , after all .
But since they are rather different than the average houseplant , it would be understandable if you misidentified some of the plant life ’s parts – or misread some of its habits .
So you’re able to choose a sound specimen and provide it with stellar care , I ’m perish to take up with a brief enlistment of poinsettia chassis and blooming cycle .
Colorful Leaves
Poinsettias are get it on and be intimate for their bright semblance , arriving flop in clip for the wintertime vacation .
But did you experience that their striking color is really in their leaves , not in their bloom ? And only some of their leafage , to be precise .
While it does have green leaves , the poinsettia also has modified leave called “ bract , ” which give us that bright holiday color we affiliate with it .
In nature , these colorful bract act like flower flower petal , serving to help draw in pollinator to the very unassuming small flowers .
Tiny Flowers
These flower are quite small , in fact , almost unrecognizable as such , and definitely not showy . They are cluster in the center of a coil of colorful bracts .
manlike and distaff flowers come out from tiny , green , bud - like complex body part called cyathia , a feature that is unequalled to fellow member of the poinsettia ’s phratry of spurges .
When you examine the blossom clusters of a poinsettia up nigh , you will notice green ovaries , honey gland that reckon like pairs of yellow-bellied back talk , and red stamens and pistil , but no petals – which is another unusual lineament of the members of the spurge family .
Instead of petals , they have the colorful , modified leaves mentioned above .
For cultivar that are not red , the stamen and pistils be given to match the colour of the bracts .
A dusting of lily-livered pollen may be seeable on the stamens , the manly part of the flower .
Trust me – I ’m not trying to nobble in a botany course here .
There is a practical reason I want you to be able to know the bloom , and it has to do with choosing a plant that will give you long - endure people of colour . I ’ll get to that in just a bit .
Blooming and Dormancy
Another of the poinsettia ’s queerness is that it reacts to shortening twenty-four hour period distance , which is phone a photoperiodic reply .
As the sidereal day shorten and the night get longer , it take this change in light-colored exposure as a cue to start farm its bloom buds and colorful bracts
TheChristmas cactusis another photoperiodic winter botch you may be intimate with , which requires long , dour nights before it will flower .
If anything interrupts those non-white night , even a nightlight , both the Christmas cactus and the Christmas flower ( aka poinsettia ) may die to make blooms .
Making trusted your Euphorbia pulcherrima is exposed to those farsighted nighttime it needs is only something you ’ll take to worry about if you be after to keep it all year .
When you grease one’s palms a poinsettia in winter , the plant life has already been take through several week of long nights to produce its beautifully colored bract .
Because of the coinage ’ reaction to its original aboriginal surround , it evolved to go through a period of dormancy after flower , dropping its bracts and leaves .
This behavior do many poinsettia owners cerebrate their specimen is drop dead – when actually , it ’s just make for a sort of hibernation , as it would have in the wild .
But before we get to the wild blood of this industrial plant , let ’s locate it among some of its congenator you may be familiar with .
Cultivation and History
As refer above , poinsettia are members of the spurge family , or in scientific argot , Euphorbiaceae .
This is a with child botanical family that include trees as well as annuals , with members as various ascrotonand thegopher plant .
WhileEuphorbiais the genus name for poinsettia , this terminal figure is also commonly used to come to to member of the spurge family .
Some genus Euphorbia are succulentand look like cacti , including a houseplant you may be familiar with – E. trigona , commonly known as the African milk tree .
But among euphorbias , poinsettia is the most beautiful one . At least that ’s what its species namepulcherrimameans – most beautiful .
lobster plant are also have a go at it by several other common names include “ lobster heyday , ” “ flaming leaf flower , ” “ paint leafage , ” and the above - mentioned “ Christmas flower , ” name which talk to the bright red bract and wintertime vividness .
In Spain , it is known as “ flor de Pascua ” – the full term “ Pascua ” is used in this instance in book of facts to the menstruum between Christmas and the celebration of the Epiphany on January 6th .
leave behind in their instinctive form , poinsettias are spindly and leggy , very dissimilar from the plants deal commercially , which are made thickset and bushy through pruning as well as other tricks of the swap ( we ’ll get to those later ) .
These plants are native to parts of North and Central America , range from Mexico to Guatemala , where they still grow dotty .
They uprise in tropical dry woodland – which are standardised to tropicalrainforests , but with lengthy periods of drouth .
Coming from these dry forests , poinsettias are wire to contend with drought conditions by undergoing a menstruation of quiescency after they finish flowering , dropping their leaves and bracts .
Boasting bright red bracts even in its lowbrow configuration , the lobster plant is a recurrent bush that can grow 10 to 20 substructure marvelous in its native kitchen range , as well as inUSDA Hardiness Zones9 to 11 .
Any plant with bright ruby-red parting would be sure to attract attention , and not only from pollinators , such as the hummingbirds that are attract to them in the wild .
The Aztecs noticed the folio of this colorful shrub , and were thefirst people known to cultivatethe poinsettia , employing its cerise bracts to make dyestuff , and using its milky white-hot sap as a medicine .
After the Spanish colonized the region , this beautiful industrial plant was used by Franciscan Thelonious Sphere Monk in Catholic nativity onward motion .
Poinsettias arrived in the US in the early 1800s , gather by Joel Roberts Poinsett , the first US ambassador to Mexico .
Poinsett was also a phytologist , and the uncouth name for the industrial plant is derive from his name . Poinsett pass away in 1851 on December 12th , and that mean solar day was identify Poinsettia Day in his memory – mark your calendar !
But it was over a hundred years after Poinsett ’s death before his namesakebecame synonymous with Christmasin the US .
It started when a German immigrant named Albert Ecke noticed this winter fuckup and began selling it at roadside stands in Los Angeles .
Over three generation , startle with Albert and reaching its high point with Paul Ecke Jr. , the Ecke family took the poinsettia – a previously unknown , spindly shrub – and turned it into a compact , colorful , commercial-grade winner that became just as much a basic of Christmas interior decoration as the Christmas tree .
The Ecke syndicate had a secret they used to create bushier specimens , and they keep their secret – and a near monopoly on the food market – until a lustrous grad educatee by the name of John Dole unwittingly figured out their whoremaster .
Dolepublished a newspaper , reveal this closed book in the former 1990s : a sure graft proficiency created well fork , and ensue in a bushier poinsettia .
The Ecke fastness on the market was ended , and with increased competition descend many fresh cultivars .
An unbelievable routine of poinsettias are now sell across the world in a just a brief amount of time each class .
In the US , around 34 million poinsettias are sold during the holiday annually , making them the secondmostcommercially importantpotted plant life in the US , right behindorchids .
Despite widespread hearsay to the reverse , the leaves and other parts of the Christmas flowerarenotpoisonous . But they are not eatable either .
In cases where these reportedly unpleasant taste leaves have been corrode , some individuals , but not all , experienced sickness , vomiting or looseness of the bowels . When these symptoms occur , they lean to pass without handling .
The bottom line is that there are no confirmed , documented cases of anyone dying , or becoming severely inauspicious from eating poinsettia .
However , those with a latex allergy or sensitive skin should take maintenance when cover painted leaf , since the white sap that transude from the leaves or stems when they are broken can cause irritation . Be certain towear glovesif you are doing any pruning .
Note : The ASPCA designates poinsettia astoxic to hound and computerized axial tomography , and also states that it is “ irritating to the rima oris and tum , sometimes cause vomiting , but generally over - rate in toxicity . ”
That means if Fido and Fluffy take a nibble of your poinsettia , they may drool , or endure from an disquieted tummy , but you do n’t have to worry about it stimulate kidney failure as some toxic houseplant are equal to of doing .
However , to be on the dependable side , keep your Christmas bloom away from curious PET , and instead stock up your rest home withnontoxic , pet - safe plantsto ward off any unnecessary vacation exigency trips to the vet .
Poinsettia Propagation
Whilepropagating Christmas star from seed is potential , most cultivars are hybrid .
So the resulting seedlings will be unpredictable in term of their genetics and ensue coming into court , make generation by stem cutting the preferred method .
root newspaper clipping can be taken from a Christmas flower purchased during the winter .
However , it ’s best to wait until the next summer when the plant is produce fresh growth to take cuttings for propagation .
When the Christmas bloom is farm new growth after emerging from dormancy , you’re able to take cuttings and root them with the help of rooting internal secretion .

Choosing a Healthy Plant
The ripe way to assure your Christmas flower lives up to its scientific name and stay on themost beautifulfor the holiday season is to start off with one that is tidy .
Were you pay attention during your Christmas star frame lesson above ? If so , your attending is about to pay off .
Here are some thing to look for when you make your choice :
This poinsettia in the photo below has cyathia which have not yet opened , which means its bract will stay fresh for a couple of month :
On the other bridge player , the bud on this one have open up and have already begin bring on pollen , which indicate that it will lose its colourful bract more quickly :
If possible , you may also want to avoid purchasing industrial plant that have been stored in container covered with cellophane wrapper over long catamenia of prison term .
These wrappers can cause untimely aging , as a result of an increase in their exposure to ethylene – the same chemical substance that causes bananas to change state brown .
Bringing Your Plant Home
It ’s not often that we institute home blossoming plant in the middle of winter , so it might not seem obvious that special charge is needed before you even get them home .
While stack away Euphorbia pulcherrima in fictile sleeves over the long full term may not be the best idea , those arm are important for protect your fresh Christmas flower from insensate and wind on the way home .
If your chosen poinsettia does n’t have a plastic sleeve , place it carefully inside a suitcase before you transport it to its lasting winter residence .
And after buying , take your Christmas flush straight home instead of allowing it to sit in an unwarmed elevator car while you do errands – Christmas star can be damage by temperatures below 50 ° farad .
Once you ’re back at home , slew the charge card sleeve to remove it , piddle if the surface of the soil feel dry , and situate your plant in its raw location .
Keep record to get hold out the best term for settle your new Christmas flower .
How to Grow Poinsettias
Whether you intend to keep on your new acquisitions full - time as houseplant , or you just want to enjoy them to clear up up the wintertime season , your Mexican flameleaf will provide better color for a long period of clip if you extend them the skillful possible care .
Temperature
While poinsettia can be grow outdoors as shrub in some areas , they are not frigid tolerantenough to survive the winter weather in most acquire zones , and must be treated as houseplant instead .
get wind more about the zoneswhere you’re able to grow this winter bloomer outdoors .
lobster plant are happiest when daytime temperatures are between 67 and 70 ° F , and when nighttime temperatures are slightly cool , in the 60 to 65 ° F kitchen range .
If this is a bit cooler than the distinctive heated winter temperature inside your house , you could insure your plants do n’t overheat by avoiding live speckle and seeking out cooler area .
Do you have a marble or granite counter , or a tile floor ? As long as they ’re not in the course of the sun or another origin of warmth , these material tend to stay cooler and will not diversify heat back up to your plants .
Another option for hold back your lobster plant assuredness is to situate it on the north side of your dwelling house , as long as it will get sufficient luminosity there – I ’ll get to clear requirements in the next section of this clause .
Although poinsettias appreciate a drop-off in temperature from day to dark , they are very sensitive to gravid temperature wavering .
That means you ’ll need to avoid placing your industrial plant very close to window , where they may get both too much heat during the Clarence Shepard Day Jr. and too much of a chill after the sunshine goes down .
Instead , place yours a substructure or so away from window . And if you have any draughty areas in your house , avert those too .
In addition to avoiding placing your Mexican flameleaf too close to overly warm south and west - facing window , you also want to avoid other blistering spots , like the tops of appliances , or country near open fireplace .
Although Christmas star see charming when lovingly nestled in next to a fireplace , when the fireplace heat up during use , you ’ll expose your flora to temperatures that are too in high spirits , and they may lose their leaves and bracts much sooner than you would trust .
Light
While situating your Christmas prime too airless to the fluctuating daily temperature of a windowpane may be a bad idea , place it a foot or so from a window may be the perfect locating for it – look on how much sunlight is streaming in through that windowpane .
These winter pants do best with six to eight hours of indirect sunlight per day , so if natural daylight is what you ’re offering them , do n’t bury to open up your blinds or curtains to let the light in .
But there is a caveat here – too much direct sun can make poinsettia bract to fade .
If you get lots of bright sunlight add up in through your windows in the winter like I do , you may require to use a sheer , light - colored curtain to turn down the light just a bit – or set your industrial plant a bit further away from the windows , where the sunlight is less intense .
If you have too small winter sunlight exposure rather than too much , you’re able to supplement this with indoor kindling .
And if you ’ve had problems providing your houseplant with ample light in the past times , you may require to consider append with lights design specifically for your leafy green familiar . Readour clause about grow lightsto learn more .
Water
In its non - torpid form , such as in the winter when it ’s blooming , you ’ll want to water your poinsettia regularly to keep its soil moist – but not soggy .
Water when the airfoil of the ground is ironic to the touch , and ensure its mess is never sitting in water .
To ensure your works has good drain , there are a few footstep you may take :
verify the plant ’s pot has drain holes in it . If it does n’t , throw out the pot for a exchangeable - sized neat pot with drainage pickle .
If the grower ’s skunk is in a cosmetic cover , carefully take away the decorative book binding and identify the plant in the swallow hole when you irrigate it . permit it drain completely before replace its decorative cover .
Mexican flameleaf often come in glasshouse jackpot that are wrapped in ornamental transparency .
If your plant is coiffure in a foil wrap , you could nose holes through the foil wrapper on the bottom to allow for drain .
I happen this figure out best if you run along up the fix that you poke in the liner with the drainage cakehole in the bottom of the pot .
When poinsettias are overwatered , the leaves may plough yellowish . On the other hand , if industrial plant are underwatered , leafage can dry out out and curl up . In both suit , leaves may start to drop .
In its dormant phase , your Mexican flameleaf should be water less oftentimes .
This frequency will reckon on conditions in your home , but as a starting power point , try watering or so once every two week , water until it drains out of the bottom of the pot .
If the prow start out to shrivel , the plant is not bring enough weewee , so increase your watering frequency . Once your Christmas flower starts to put out new outgrowth , return to a regular watering schedule .

Humidity
Although they do n’t care to be overwatered , these plants do favor a humid environs . supply them with a footling humidity will make their color last longer .
Since indoor heating tend to dry out out our homes during the winter , misting the foliage can help to provide them with the humidity they postulate .
Make trusted to obnubilate in the good morning , so the farewell have time to dry out before temperature fall at night .
Another way to offer tropical houseplants a humid surroundings is to place a humidity tray underneath them .
you could make your own by filling a shallow tray with clean pebbles and then filling it with water .
Place your pot Christmas star on top of the tray . The water in the tray will evaporate into the air , increasing the humidity around the works .
Soil
You wo n’t take to worry about soil for your poinsettia – unless you contrive to keep it as a houseplant class - round .
If you do cease up keeping your flora on permanently , be aware that poinsettias do well with a well - draining , somewhat acidic stain mix .
Potting soil contain coconut coir , such as Tank ’s Pro Coco - Soil Potting Mix , will work for this use . You canfind it at Arbico Organics .
Tank ’s Pro Coco - Soil Potting Mix
During the develop time of year , you may notice your Christmas flower start out to dry out more quickly than it was antecedently . This may be a house of it becoming rootbound , in which case , it ’s a good idea to repot it .
When repot , check that to pick out a lot with drain hole and only move your flora up to the next sized deal , to forestall the excess grime around the roots from becoming waterlogged .
Fertilizer
Your poinsettias will not need to be fertilized while they are in heyday .
If you decide to keep your Christmas heyday year - orotund , fertilise them during bounce and summer once their foliation has begun to grow back .
Poinsettias are jolly flexible in their fertilize requirement .
While for commercial output , a fertilizer low in phosphorus and in high spirits in atomic number 19 is often commend , for home consumption , an all - purpose houseplant fertilizer diluted to half strength can be employ once every three weeks .
Personally , I prefer to take the most natural path potential when fertilise my houseplant , draw my plant food of choiceworm composttea .

Growing Tips
Maintenance
After the holidays are over , be aware that your Christmas flower will set about to drop its leaves and bract in recent wintertime – this is normal , and part of the plant ’s quiescence catamenia .
When it has dropped half of its leaves and bracts , start to decrease the amount of piddle you cater .
To help it accomplish the conditions it call for for quiescency , place it in a cool room and concentrate watering to about once every two calendar week .
If you want it to renew its brilliantly colored bract in time for the holiday year after twelvemonth , every autumn your poinsettia will need ten weeks of recollective , 13- to 14 - hour nights with no ambient light .

Disease
Unless you are beautify your bath with this winter foul-up , the shape in most people ’s nursing home during the vacation time of year do n’t lend themselves to the majority of diseases that smite Christmas prime , most of which flourish in high humidness .
However , when they are infected , poinsettias can be difficult to do by . utilise prevention as your best tactic , and look for telltale sign of disease before purchasing these plant .
Bacterial folio pip is a bacterial disease that also affects love apple and turnips , among other plants . It thrives when atmospheric condition are warm and humid , and can be spread by slosh water , or through taint from old , infected plant debris .
In poinsettias , the pains of bacteria that causes this disease isXanthomonas campestrispv.poinsettiicola , and it can attest in symptoms such as yellow or tan lesion on leaves . If the disease come on , you will also detect leaves yellow , becoming falsify , and falling off .
Prevention is the best means of check this disease . Look for salubrious plants before buy , keep them out of sloshed conditions , and provide adequate ventilation .
Poinsettia strikebreaker is because of a fungus calledSphaceloma poinsettiae . This scab is a blot anthracnose disease , and its symptom include small yellow spots on leaves , or as the disease progresses , raised brown pip with yellow halos around them .
These spots are discover specially along the main leaf vein . When the spots are brown and parent , they will take on a velvety appearance . wound can be found on prow as well , causing septic stem to stretch .
