Bougainvillea is a surprising flowering vine that finds its origins in South America. Native predominantly from Brazil to Peru and south to Argentina, this beautiful tropical plant has discovered its technique to many tropical and subtropical areas worldwide.
Beloved for its ease of care and spectacular floral shows, the plant could be very standard in the US and the Mediterranean area of Europe. Rising up in Southeast Florida, I can recall seeing this beautiful plant climbing the outside of many an outside shopping center or ocean-side restaurant.
The plant was first recorded by a European botanist in 1789, and it claims its identify from the French Navy admiral who captained the ship on which this botanist traveled. There’s some query as as to if or not it was recorded by Philbert Comerrcon or his lover and assistant, Jeanne Baret. As ladies weren’t allowed on navy ships, Ms. Baret, an skilled botanist, disguised herself as a person to make the journey.
The most important bougainvillea plant in the US is on the Nationwide Register of Historic Locations and can be a California state historic website. Planted in 1901 by citrus growers, the bougainvillea remains to be rising sturdy as we speak in Glendora, California.

Classification

Bougainvillea is a flowering, tropical evergreen plant within the Nyctaginaceae household. This household is extra generally often called 4 O’Clocks. This identify is derived from the behavior of flowering round this time of day. Crops on this household are late afternoon bloomers. Their flowers open within the night and are pollinated at evening.
The Bougainvillea genus is giant and colourful. It consists of about 18 species and greater than 300 totally different types of flowering, woody vines. They’re tropical crops that may survive in sub-tropical climates or are grown as annuals in colder climates.
Some smaller species can be grown in containers and stored year-round so long as they’re moved indoors throughout extended chilly climate or a tough freeze.
Flowers

Greatest identified for what most individuals acknowledge as its bountiful and colourful blooms, the colourful parts of the bougainvillea plant are literally not flowers in any respect. The colourful parts of foliage are bracts that are nearer in kind to leaves than they’re to flowers. Like poinsettia crops, these bracts are far more colourful and showy than their actual flowers.
The precise flowers of the bougainvillea plant are very small and tucked away contained in the bracts for cover. Whereas the bracts are available many shades of pink, purple, orange, yellow, crimson, and white, the precise flowers are normally white or pale yellow. Whereas a plant might produce an abundance of colourful bracts year-round, probably the most prolific seasons are late spring, summer time, and fall. The cooler the local weather, the sparser the bracts will probably be within the winter.
A higher blooming season is often preceded by a dry winter. There are different strategies of accelerating the incidence of those colourful bracts, like utilizing a low-nitrogen fertilizer or pruning the plant closely within the early spring.
Leaves

The leaves are giant, easy, and ovate, are usually clean, however can have small hairs on the underside of the leaves. They are often stable inexperienced to bluish-green or variegated. Whereas bougainvillea is normally grown for its colourful bracts, a combination of leaves and bracts creates a good looking mixture.
The ratio of bracts to leaves may be managed by two components: daylight and fertilizer. Extra solar and fewer nitrogen will encourage the expansion of extra bracts, whereas much less publicity and extra nitrogen will encourage extra inexperienced progress. Nonetheless, inadequate daylight can result in leggy progress. That is not plant for a shade backyard.
Propagation
Bougainvillea may be propagated by two means, with one taking a particular lead in buying a mature plant. Each are straightforward to acquire, however propagation by cuttings is often considered probably the most handy and profitable methodology.
Seeds

Bougainvillea seeds are usually not troublesome to accumulate however are identified for troublesome germination. It usually takes as much as 30 days for bougainvillea seeds to sprout, and so they don’t have a superb germination charge. Nonetheless, should you intend to develop bougainvillea for bonsai, rising from seed will yield one of the best outcomes.
Seeds may be harvested from a plant fairly simply. The seed pods may be discovered contained in the bracts the place a flower has bloomed and fallen. These pods every comprise 3 seeds. These seeds ought to be planted in a well-draining potting combine and stored in a heat sunny spot till they’re giant sufficient to be transplanted.
Cuttings

The commonest and standard methodology of propagating bougainvillea is cuttings. Since these crops wish to be pruned to supply new progress and loads of colourful bracts, The perfect time to propagate is within the spring, after you may have pruned your plant. This additionally provides you new reducing probably the most time to grow to be established throughout an lively progress interval.
The thicker the reducing, the sooner your reducing will root, reaching a bushier plant. Nonetheless, any reducing the width of a pencil or higher will work. Scraping the bark from the underside finish of the reducing will encourage sooner rooting. Scrape bark from the decrease 2” of the reducing.
Put together a 5” or bigger pot with a rough, well-draining potting medium. Coarse sand blended with peat or soil and perlite is an efficient possibility for rooting these cuttings. Dip the scraped finish of the reducing water, shake off any extra, then roll it in a powdered rooting hormone. Fastidiously place it in a gap within the soil, urgent the soil firmly across the cuttings.
For a number of weeks, your reducing will want constant moisture and vibrant, oblique mild. In case you wouldn’t have an area with pretty important humidity, you should utilize plastic wrap or a plastic container over the pot to take care of moisture. In case your cuttings are profitable, they’ll produce leaves in a number of weeks. Pruning the guidelines of latest branches will encourage extra branching.
Planting

Bougainvillea may be planted in spring or summer time. This offers your plant ample time to set roots and grow to be established in its new location. Take care when planting these crops; their stems have quite giant, stiff, and sharp thorns. Sporting high quality pair of gloves helps shield your palms when planting or pruning this plant.
Crops ought to be positioned 2’-3’ aside to keep away from crowding. Largely, these crops develop lengthy however not terribly large, though you may encourage branching with pruning. Dig a gap that’s as deep and twice as large as your plant’s root ball. Place your plant within the gap and backfill.
The best way to Develop
Below the best circumstances, it is a fast-growing and hard plant. With the best care, your Bougainvillea will probably be a considerable plant by the top of the season. A very powerful components are the soil kind and the quantity of daylight your plant receives. These two issues comprise the higher a part of the components necessary in rising a big, wholesome bougainvillea plant.
Containers

In case you stay in a colder local weather and are rising your bougainvillea in a container, select a pretty big however moveable one, because the plant will want shelter in freezing climate. A very powerful consider selecting a container for this plant is drainage. A big material develop bag will encourage root power and density and permit ample drainage.
Gentle

Bougainvillea are sun-loving crops. Whereas they’ll nonetheless stay in partial shade, they have an inclination to get leggy, and you find yourself with many branches, thorns, and little or no foliage. This consists of their colourful bracts. These crops require no less than 6 hours of solar day by day to supply their bracts in any important quantity.
There’s virtually no such factor as an excessive amount of solar for these crops. They honestly rise up splendidly to warmth and solar. I can’t say I’ve ever seen a sun-damaged or wilted bougainvillea.
You’re way more more likely to lose one in all these crops to overwatering than to overexposure to the solar. The extra solar your plant receives, the extra coloration it would produce, and a scarcity of daylight will end in extra inexperienced progress.
Soil

Drainage is the important thing phrase the place soil kind is anxious for this plant. In case your soil could be very sandy, think about amending it with some well-rotted compost or manure so as to add vitamins.
Bougainvillea tends towards root rot if the roots are stored soggy, so soil that’s too wealthy or dense ought to be amended with coarse sand or different giant particles to interrupt up the density and permit for correct drainage.
Water

For probably the most half, bougainvillea is properly suited to sizzling, dry climate. As soon as established, these crops can go for weeks with out watering and are unlikely to undergo from drought besides in excessive instances.
In case you expertise a big, prolonged interval of drought, water your plant deeply each 2-3 weeks. Watering sometimes however deeply will probably be higher on your bougainvillea roots than shallow waterings extra continuously. This plant is happiest when its roots dry out between waterings.
A bougainvillea can undergo from a scarcity of water in excessive warmth and low rainfall. Your plant will let you recognize that is the case by wilting. If it wilts, it wants an extended drink of water.
Local weather and Temperature

Bougainvillea does not tolerate freezing climate. In case you are rising in a container in a cooler local weather, it’s best to offer the pot winter safety when the temperature drops under 50°F. Within the floor, bougainvillea will undergo injury to leaves and bracts when the temperature drops under 40°F and will die again in a freeze.
Intervals of extended freezing climate are more likely to injury the roots as properly. Some varieties, reminiscent of San Diego Crimson, are thought-about to be extra cold-tolerant than others.
By way of warmth, bougainvillea could be very tolerant. Nonetheless, should you stay in a local weather that continuously experiences temperatures of over 100°F, provide your plant some shade within the afternoon.
Fertilizer

Bougainvillea crops wish to be fertilized throughout their rising interval. From early spring till late summer time, you may fertilize each 6-8 weeks, and your plant will soak it up and reward you handsomely.
One thing to recollect is that totally different vitamins encourage various kinds of progress. Extra nitrogen could cause extra inexperienced progress and fewer improvement of colourful bracts. That isn’t to say that the plant gained’t make the most of the nitrogen you give it, nitrogen will trigger sooner progress, but it surely simply gained’t assist the plant deal with producing bracts, which most gardeners choose.
Whereas your plant is getting established, feed it a balanced fertilizer for ample progress and root improvement. A ten-10-10 formulation will do the trick. As soon as the plant is established, change to a fertilizer increased in potassium. That is represented by the third quantity within the fertilizer formulation or the “Ok” of NPK. The extra potassium will encourage the event of bracts and flowers.
Upkeep and Care

Bougainvillea is a no-fuss plant, significantly as soon as it’s established. It would use fertilizer should you present it. In any other case, this can be very warmth and drought-tolerant and doesn’t want a lot common care.
The exception to that is pruning. Pruning will encourage branching and fuller, bushier progress. Pruning small quantities whereas the plant is younger will assist the plant to develop extra branches, and important pruning within the early spring will preserve your plant’s foliage dense and plush.
