How to Grow and Care for Poinsettia Plants

In reality, in some methods, poinsettias are fairly resilient. Their unusual development behavior, with its interval of sparse-looking dormancy, serves as an excellent reminder that simply because issues would possibly look dangerous now, that doesn’t imply a brand new interval of vitality and sweetness isn’t simply across the nook.

Past such metaphysical meditations, poinsettias fairly actually brighten up the darkish winter months spent indoors.

Poinsettias are among the many most colourful vegetation you may develop indoors, and though we have a tendency to contemplate them mainly to be a (maybe disposable) a part of the vacation decor, it’s essential to keep in mind that they’re alive and wish caretaking, identical to different houseplants.

I’m going to offer you a information to caring to your poinsettia, and I’ll let you know about a number of the attention-grabbing quirks in its pure historical past.

Right here’s what I’ll cowl:

What Are Poinsettias?

Poinsettia, pronounced “poyn-set-ee-uh,” or simply as generally, “poyn-set-uh,” is a well-liked vacation plant, utilized in specific to embellish through the Christmas season.

You’d most likely acknowledge this winter bloomer, which fits by the scientific title Euphorbia pulcherrima, after only a fast look – they appear to be nearly in all places through the holidays, in spite of everything.

However since they’re quite totally different than the typical houseplant, it will be comprehensible for those who misidentified a number of the plant’s components – or misinterpreted a few of its habits.

So you may select a wholesome specimen and supply it with stellar care, I’m going to start out with a short tour of poinsettia anatomy and blooming cycle.

Colourful Leaves

Poinsettias are identified and beloved for his or her brilliant colours, arriving proper in time for the winter holidays.

However do you know that their hanging colour is definitely of their leaves, not of their flowers? And solely a few of their leaves, to be exact.

Whereas it does have inexperienced leaves, the poinsettia additionally has modified leaves referred to as “bracts,” which give us that brilliant vacation colour we affiliate with it.

In nature, these colourful bracts act like flower petals, serving to assist entice pollinators to the very unassuming small flowers.

Tiny Flowers

These flowers are fairly small, in actual fact, virtually unrecognizable as such, and positively not showy. They’re clustered within the middle of a whorl of colourful bracts.

Female and male flowers emerge from tiny, inexperienced, bud-like buildings referred to as cyathia, a function that’s distinctive to members of the poinsettia’s household of spurges.

While you study the flower clusters of a poinsettia up shut, you’ll discover inexperienced ovaries, nectaries that appear to be pairs of yellow lips, and purple stamens and pistils, however no petals – which is one other uncommon function of the members of the spurge household.

As a substitute of petals, they’ve the colourful, modified leaves talked about above.

For cultivars that aren’t purple, the stamens and pistils are likely to match the colour of the bracts.

A dusting of yellow pollen could also be seen on the stamens, the male a part of the flower.

Belief me – I’m not making an attempt to sneak in a botany class right here.

There’s a sensible cause I would like you to have the ability to acknowledge the flowers, and it has to do with selecting a plant that will provide you with long-lasting colour. I’ll get to that in only a bit.

Blooming and Dormancy

One other of the poinsettia’s quirks is that it reacts to shortening day size, which is known as a photoperiodic response.

As the times shorten and the nights get longer, it takes this variation in gentle publicity as a cue to start out producing its flower buds and colourful bracts

The Christmas cactus is one other photoperiodic winter bloomer you could be accustomed to, which requires lengthy, darkish nights earlier than it can flower.

If something interrupts these darkish nights, even a nightlight, each the Christmas cactus and the Christmas flower (aka poinsettia) might fail to supply blooms.

Ensuring your poinsettia is uncovered to these lengthy nights it wants is barely one thing you’ll want to fret about for those who plan to maintain all of it 12 months.

While you purchase a poinsettia in winter, the plant has already been taken via a number of weeks of lengthy nights to supply its fantastically coloured bracts.

Due to the species’ response to its unique native surroundings, it advanced to undergo a interval of dormancy after blooming, dropping its bracts and leaves.

This conduct makes many poinsettia house owners assume their specimen is dying – when truly, it’s simply getting ready for a form of hibernation, as it will have within the wild.

However earlier than we get to the wild origins of this plant, let’s situate it amongst a few of its relations you could be accustomed to.

Cultivation and Historical past

As talked about above, poinsettias are members of the spurge household, or in scientific lingo, Euphorbiaceae.

This can be a massive botanical household that features bushes in addition to annuals, with members as various as croton and the gopher plant.

Whereas Euphorbia is the genus title for poinsettia, this time period can also be generally used to check with members of the spurge household.

Some euphorbias are succulent and appear to be cacti, together with a houseplant you could be accustomed to – E. trigona, generally often known as the African milk tree.

However amongst euphorbias, poinsettia is probably the most stunning one. A minimum of that’s what its species title pulcherrima means – most stunning.

Poinsettias are additionally identified by a number of different frequent names together with “lobster flower,” “flame leaf flower,” “painted leaf,” and the above-mentioned “Christmas flower,” names which converse to the brilliant purple bracts and wintertime colour.

In Spain, it is called “flor de Pascua” – the time period “Pascua” is used on this case in reference to the interval between Christmas and the celebration of the Epiphany on January sixth.

Left of their pure type, poinsettias are spindly and leggy, very totally different from the vegetation bought commercially, that are made compact and bushy via pruning in addition to different tips of the commerce (we’ll get to these later).

These vegetation are native to components of North and Central America, starting from Mexico to Guatemala, the place they nonetheless develop wild.

They originated in tropical dry forests – that are just like tropical rain forests, however with prolonged intervals of drought.

Coming from these dry forests, poinsettias are wired to deal with drought circumstances by present process a interval of dormancy after they end flowering, dropping their leaves and bracts.

Boasting brilliant purple bracts even in its uncultivated type, the poinsettia is a perennial shrub that may develop 10 to twenty toes tall in its native vary, in addition to in USDA Hardiness Zones 9 to 11.

Any plant with brilliant purple leaves would make sure you entice consideration, and never solely from pollinators, such because the hummingbirds which are drawn to them within the wild.

The Aztecs seen the leaves of this colourful shrub, and have been the primary folks identified to domesticate the poinsettia, using its purple bracts to make dye, and utilizing its milky white sap as a drugs.

After the Spanish colonized the area, this stunning plant was utilized by Franciscan monks in Catholic nativity processions.

Poinsettias arrived within the US within the early 1800s, collected by Joel Roberts Poinsett, the primary US ambassador to Mexico.

Poinsett was additionally a botanist, and the frequent title for the plant is derived from his title. Poinsett died in 1851 on December twelfth, and that day was named Poinsettia Day in his reminiscence – mark your calendars!

But it surely was over 100 years after Poinsett’s dying earlier than his namesake grew to become synonymous with Christmas within the US.

It began when a German immigrant named Albert Ecke seen this winter bloomer and started promoting it at roadside stands in Los Angeles.

Over three generations, beginning with Albert and reaching its excessive level with Paul Ecke Jr., the Ecke household took the poinsettia – a beforehand unknown, spindly shrub – and turned it right into a compact, colourful, industrial success that grew to become simply as a lot a staple of Christmas decor because the Christmas tree.

The Ecke household had a secret they used to create bushier specimens, they usually saved their secret – and a close to monopoly available on the market – till a brilliant grad scholar by the title of John Dole inadvertently found out their trick.

Dole revealed a paper, revealing this secret within the early Nineties: a sure grafting method created higher branching, and resulted in a bushier poinsettia.

The Ecke stronghold available on the market was ended, and with elevated competitors got here many new cultivars.

An unbelievable variety of poinsettias at the moment are bought the world over in a only a transient period of time every year.

Within the US, round 34 million poinsettias are bought through the holidays yearly, making them the secondmost commercially essential potted plant within the US, proper behind orchids.

Regardless of widespread rumor on the contrary, the leaves and different components of the Christmas flower will not be toxic. However they don’t seem to be edible both.

In circumstances the place these reportedly disagreeable tasting leaves have been eaten, some people, however not all, skilled nausea, vomiting or diarrhea. When these signs happen, they have an inclination to cross with out remedy.

The underside line is that there aren’t any confirmed, documented circumstances of anybody dying, or changing into gravely in poor health from consuming poinsettia.

Nonetheless, these with a latex allergy or delicate pores and skin ought to take care when dealing with poinsettias, for the reason that white sap that oozes from the leaves or stems when they’re damaged may cause irritation. Make sure you put on gloves in case you are doing any pruning.

Observe: The ASPCA designates poinsettia as poisonous to canines and cats, and likewise states that it’s “irritating to the mouth and abdomen, typically inflicting vomiting, however typically over-rated in toxicity.”

Meaning if Fido and Fluffy take a nibble of your poinsettia, they might drool, or undergo from an upset tummy, however you don’t have to fret about it inflicting kidney failure as some poisonous houseplants are able to doing.

Nonetheless, to be on the secure facet, preserve your Christmas flower away from curious pets, and as a substitute inventory your own home with unhazardous, pet-safe vegetation to keep away from any pointless vacation emergency journeys to the vet.

Poinsettia Propagation

Whereas propagating poinsettias from seed is feasible, most cultivars are hybrids.

So the ensuing seedlings shall be unpredictable when it comes to their genetics and ensuing look, making propagation by stem cuttings the popular technique.

Stem cuttings could be taken from a poinsettia bought through the winter.

Nonetheless, it’s greatest to attend till the subsequent summer time when the plant is producing new development to take cuttings for propagation.

When the Christmas flower is producing new development after rising from dormancy, you may take cuttings and root them with the assistance of rooting hormone.

Selecting a Wholesome Plant

If potential, you might also wish to keep away from buying vegetation which have been saved in containers lined with cellophane wrappers over lengthy intervals of time.

These wrappers may cause untimely growing older, on account of a rise of their publicity to ethylene – the identical chemical that causes bananas to show brown.

Bringing Your Plant Dwelling

It’s not typically that we deliver house flowering vegetation in the course of winter, so it may not appear apparent that particular care is required earlier than you even get them house.

Whereas storing poinsettias in plastic sleeves over the long run will not be the perfect concept, these sleeves are essential for safeguarding your new Christmas flower from chilly and wind on the best way house.

In case your chosen poinsettia doesn’t have a plastic sleeve, place it rigorously inside a bag earlier than you transport it to its everlasting winter residence.

And after buying, take your Christmas flower straight house as a substitute of permitting it to sit down in an unheated automotive whilst you do errands – poinsettias could be broken by temperatures beneath 50°F.

When you’re again at house, lower the plastic sleeve to take away it, water if the floor of the soil feels dry, and situate your plant in its new location.

Maintain studying to seek out out the perfect circumstances for finding your new Christmas flower.

Temperature

Whereas poinsettias could be grown outdoor as shrubs in some areas, they don’t seem to be chilly tolerant sufficient to outlive the winter climate in most rising zones, and have to be handled as houseplants as a substitute.

Study extra concerning the zones the place you may develop this winter bloomer outdoor.

Poinsettias are happiest when daytime temperatures are between 67 and 70°F, and when nighttime temperatures are barely cooler, within the 60 to 65°F vary.

If it is a bit cooler than the standard heated winter temperatures inside your own home, you may guarantee your vegetation don’t overheat by avoiding scorching spots and searching for out cooler areas.

Do you could have a marble or granite counter, or a tile flooring? So long as they’re not within the path of the solar or one other supply of warmth, these supplies have a tendency to remain cooler and won’t radiate warmth again as much as your vegetation.

An alternative choice for retaining your poinsettia cool is to situate it on the north facet of your own home, so long as it can obtain adequate gentle there – I’ll get to gentle necessities within the subsequent part of this text.

Though poinsettias recognize a drop in temperature from day to nighttime, they’re very delicate to massive temperature fluctuations.

Meaning you’ll wish to keep away from inserting your vegetation very near home windows, the place they might get each an excessive amount of warmth through the day and an excessive amount of of a chill after the solar goes down.

As a substitute, place yours a foot or so away from home windows. And when you have any drafty areas in your house, keep away from these too.

Along with avoiding inserting your poinsettia too near overly heat south and west-facing home windows, you additionally wish to keep away from different scorching spots, just like the tops of home equipment, or areas close to fireplaces.

Though poinsettias look charming when lovingly nestled in subsequent to a hearth, when the fireside heats up throughout use, you’ll expose your vegetation to temperatures which are too excessive, they usually might lose their leaves and bracts a lot prior to you’ll hope.

Mild

Whereas situating your Christmas flower too near the fluctuating each day temperatures of a windowpane could also be a nasty concept, inserting it a foot or so from a window would be the excellent location for it – relying on how a lot daylight is streaming in via that window.

These winter bloomers do greatest with six to eight hours of oblique daylight per day, so if pure daylight is what you’re providing them, don’t neglect to open your blinds or curtains to let the sunshine in.

However there’s a caveat right here – an excessive amount of direct daylight may cause poinsettia bracts to fade.

If you happen to get a number of brilliant daylight coming in via your home windows within the winter like I do, you could wish to use a sheer, light-colored curtain to show down the sunshine only a bit – or place your plant a bit additional away from the home windows, the place the daylight is much less intense.

When you have too little winter daylight publicity quite than an excessive amount of, you may complement this with indoor lighting.

Poinsettias typically are available in nursery pots which are wrapped in ornamental foil.

In case your plant is wearing a foil wrapper, you may poke holes via the foil wrapper on the underside to offer drainage.

I discover this works greatest for those who line up the holes that you just poke within the liner with the drainage holes within the backside of the pot.

When poinsettias are overwatered, the leaves might flip yellow. Then again, if vegetation are underwatered, leaves can dry out and curl up. In each circumstances, leaves might begin to drop.

In its dormant section, your poinsettia must be watered much less regularly.

This frequency will depend upon circumstances in your house, however as a place to begin, attempt watering roughly as soon as each two weeks, watering till it drains out of the underside of the pot.

If the stems begin to shrivel, the plant is just not getting sufficient water, so improve your watering frequency. As soon as your Christmas flower begins to place out new development, return to a daily watering schedule.

Humidity

Though they don’t prefer to be overwatered, these vegetation do favor a damp surroundings. Offering them with a bit of humidity will make their colour last more.

Since indoor heating tends to dry out our houses through the winter, misting the foliage can assist to offer them with the humidity they want.

Ensure to mist within the morning, so the leaves have time to dry earlier than temperatures fall at night time.

One other method to supply tropical houseplants a damp surroundings is to position a humidity tray beneath them.

You may make your individual by filling a shallow tray with clear pebbles after which filling it with water.

Place your potted poinsettia on prime of the tray. The water within the tray will evaporate into the air, rising the humidity across the plant.

Poinsettias are pretty versatile of their fertilizing necessities.

Upkeep

After the vacations are over, bear in mind that your Christmas flower will start to drop its leaves and bracts in late winter – that is regular, and a part of the plant’s dormancy interval.

When it has dropped half of its leaves and bracts, begin to lower the quantity of water you present.

To assist it obtain the circumstances it wants for dormancy, place it in a cool room and cut back watering to about as soon as each two weeks.

If you’d like it to resume its brightly coloured bracts in time for the vacations 12 months after 12 months, each autumn your poinsettia will want ten weeks of lengthy, 13- to 14-hour nights with no ambient gentle.
