There ’s nothing restrained about cattleya .
They celebrate sprightliness exuberantly with ruffled petals , bright colors , and a public violence of splotches , floater , and stripes . The flower vein often contrast with the rest , in darker shades .
These are not shy , retiring flowers . They want to be seen .
It ’s not for nothing that these pretentious plants are often referred to as the “ Queen of the Orchids . ” It ’s well-heeled to picture them clothe the interior of a purple castle just as they adorn the wrist and shoulder of the most stylish women in the 1950s .
We ’d obviouslyneverplay favourite with our plants , but I would n’t approximate you one mo if you whispered supererogatory run-in of love and boost to yours each time you walked by .
We ’ll help oneself you make your royal visitor find welcome in your own palace . Here ’s a quick prevue of everything we ’ll hash out to make that come about :
What You’ll Learn
Through the abbreviated span of a few decade in the 1940s and ‘ 50s , if you were going to buy an orchidaceous plant in the US , it was in all probability a cattleya .
By the 1960s , cymbidiums take over . These days , their genus Phalaenopsis full cousin are all the rage , but cattleyas are still every bit as fabulous as they ever were .
Cultivation and History
Cattleyaspecies grow wild across Costa Rica and South America at gamy EL where the air is moist and cool .
Most of them areepiphytes , which means they raise on other plants , unremarkably trees . But they are n’t parasite , and they just expend the server plant as a means of support .
The name “ cattleya ” comes from British plantsman William Cattley , who get a shipment of plants from Brazil in 1818 .
In the shipment was an orchid , previously identify by William John Swainson , that was await pretty grim , but he nurtured it back to health . Known for his love for orchids , the genus was eventually key out in his honor .
Within the genus , there are four subgenera – Cattleya , Cattleyella , Intermediae , andMaximae .
There are three sections within theCattleyasubgenus – Cattleya , Crispae , andLawrenceanae – with five serial grouped under theCrispaesection . These areCattleyodes , Hadrolaelia , Microlaelia , Parviflorae , andSophronitis .
There are about 45 know species in the genus , only a few of which are terrestrial rather than epiphytic . They earn the name “ corsage orchids ” due to their popularity among florists for this design in the mid-20th 100 .
The most commonly civilise mintage isC. labiata , which is the species that Swainson , a polymath from London who made written report of the natural world his life-time ’s work , find in Brazil .
Cattleyas differ from other orchidaceous plant in that they usually have larger flowers with an vivid fragrance , but these blossoms also last for a short stop of time .
The prime number in a massive range of coloring material , admit white-hot , cream , yellow , orangish , light-green , pinkish , red , magenta , lavender , reddish blue , and nearly blue , but not true blue angel .
Typically , the lowermost petal ( i.e. the labellum or lip ) is a different color from the rest . The lip are usually ruffled and funnel - shaped .
These plants have thick , oblong , sensationalistic - green leave . And there are two types of cattleyas , where foliation is concerned : unifoliates and bifoliates . Unifoliate case have a undivided folio on each pseudobulb , and bifoliate types have two or three farewell each .
In character you are n’t already an expert on orchid biology , a pseudobulb is a little electric-light bulb - like storage structure that maturate below the leaves and above the roots .
True bulbs grow underground , whereas pseudobulbs grow above the soil .
A exclusive plant can have multiple pseudobulb emerging from the roots . orchid with pseudobulbsare described as sympodial , which means the pseudobulbs come forth horizontally along the rhizome .
Compare that toPhalaenopsisspecies , for instance , which grow upward rather than out , with leaves stacking on top of each other and flower spike that egress from between the leaves . This is know as monopodial growth .
Bifoliate type typically produce lots of small , waxy blossom . Unifoliate types have magnanimous flowers , and these are the single that were so wildly pop for exercise in corsage .
Bifoliates includeC. bicolor , C. elongata , C. granulosa , C. intermedia , C. schilleriana , C. tigrina , C. velutina , andC. violacea . Unifoliates includeC. dowiana , C. gaskelliana , C. labiata , C. mendelii , C. percivaliana , C. quadricolor , C. rex , andC. warneri .
Propagation
Most of us buy our orchids as potted specimen . It ’s just easier that way . But it ’s possible to maturate them from seed as well , and this is how hobbyist interbreed them to create new varieties .
We wo n’t dive into the complexities of distribute orchids from seed here . It ’s achievable , but it ’s time - consuming and requires particular equipment .
If you ’d like to give it a go , we have acomprehensive guide to the processthat you might find useful .
For now , let ’s just chat about what to do when you buy a nosegay orchidaceous plant in a container .
From Potted Nursery Plants/Transplanting
Most of the time , when you buy an orchidaceous plant , it come in a soilless medium in a pot with multiple drain holes .
If that ’s the case , you do n’t ask to do anything . Just keep caring for your industrial plant until it ’s sentence to size up the container , which we ’ll blab out about in a piece .
But if you buy plug or an orchidaceous plant that ’s growing in soil , you ’ll need to repot it when you bring it home .
You must be very careful not to “ over - pile ” cattleyas – this is a shortcut that will lead only to root rot . Choose a pot that is about the same size or just slightly larger than the root orchis .
Also be certain toselect a container for your orchidwith lots of drainage holes . Pots designed specifically for grow orchidaceous plant are available , and you may put these inside a cosmetic cachepot without drainage hole if you like . Just be sure to remove the cachepot when you water .
You might desire to keep orchid pot in several different sizes on hand because you ’ll need to repot every few years .
Orchid Pots
you could grab a multipack of eight toilet with two each in three- , four- , five- , and six - inch sizes from rePotmeat Amazon .
take out the plant from the container you purchased it in and remove all of the pot medium from around the root . Cut away any rotten , mushy , or broken roots .
Repot in orchid barque in a pot of the same size or just one size up from the one it was already growing in .

How to Grow
Cattleyas do n’t wish being live , and their temperature determines how much Light Within they can handle .
Touch your plant ’s leaf . Does it feel warm ? The plant is too hot .
If the industrial plant is kept humid with plenty of air circulation to reduce the temperature , it can tolerate partial sun . But in the average home , you ’ll desire something cheeseparing to fond ghost .
Or course , both of these light condition are more distinctive of outside horticulture passport . So what does that interpret to inside your menage ? And what does “ medium ” really have in mind anyway ?
brilliant , indirect light is going to be perfect . For many gardeners , this may mean place the orchid in an east - facing window insure with a sheer drapery .
If you haveaccess to a light beat , about 2,000 to 3,000 foot - cd is ideal – unlessyou have in force humidity ( which we ’ll discourse shortly ) and strain circulation .
If you have both of these elements uncommitted you may offer a bit more low-cal , which will translate to more blossoms that are larger as well .
Also , if you live in a northern region , which typically gibe with reduced sunshine for a meaning part of the twelvemonth , you could provide more light , while those in more southerly latitude should provide less .
These orchidaceous plant can also tolerate more light exposure in the fall and winter than they can in the spring and summer when the light is more intense and direct .
Gardeners in places like Hawaii and Florida where the weather is hot and humid and the spark is more intense should supply dimmer light , whether that ’s indoors or out .
Never allow these plant life to be exposed to full sun in the heat of the afternoon . Some direct morning sun in northern latitudes is fine .
Now that we ’ve gotten all those recommendation out of the style … About clear as mud , right ? ?
endeavor to use the items note above as a rule of thumb and start out in a slightly darker area than you cogitate your plant will need . Then bit by bit move the orchid into brighter sun .
If the plant is moved into a location with too much sunlight , the first sign will be carmine - purple splodge or floater on the foliation . Then , the leaf gratuity will turn dry and brown . Next , if overexposure continues , the leave will start to turn yellow as the chlorophyll degenerates .
If it receive the right amount of the lightness , your plant will have yellowish - immature farewell . Too little Light Within turns the leaves dark green , which might sound pretty , but it also forestall the plant from flowering . If you see dark green leaves and your plant life is n’t blooming , it ’s in a spot that ’s too dark .
temperature should range from 55 ° atomic number 9 at night to 75 ° F in the heat of the day . These orchids can easily tolerate temperatures up to 85 ° F if they ’re protected from unmediated sun , but they ’ll pass if temporary climb above 100 ° F , no matter how protected they are .
humidness should be between 40 and 70 percent . If the proportional humidity is lower than this in your home , pebble trays filled with water , cool mist humidifiers , and grouping industrial plant together can avail to increase humidity .
Now that we ’ve make the “ easygoing ” hooey out of the way , have ’s talk about irrigation . Over- or underwatering orchid is their number one killer . It ’s essentially the center disease of orchids .
Lucky for orchid , it ’s a lot easier toprevent this problemthan it is to forestall heart disease in humans .
First , know that the conditions in the ring environment will make a big difference in how much water system the plant needs .
A cattleya with bright Lord’s Day photograph , good tune circulation , a small throne , and modest ambient humidness during the combat-ready growing time of year will need a lot more water than a sleeping plant in a dark sphere with poor airwave circulation and high humidness .
The well-heeled path to figure thing out is to touch the growing mass medium . The aerofoil should feel dry and the sensitive should be almost whole dry throughout .
It ’s unremarkably going to be unacceptable to cohere your finger too deep into the medium since it will typically be compose of chunks of barque and filled with a long ton of roots , so learn to tell by gauging the weight of the pot alternatively .
Lift the pot to get an idea of its free weight powerful after you body of water . Then , wait a few days until the medium has dried out . arise the pot again and feel the difference .
It takes time to recognise pronto , but finally you ’ll be capable to state when it ’s clip to water just by feeling the weight unit of the container . Amoisture metermakes it easy to check when it ’s time to irrigate too .
Underwatering is less detrimental to most orchids than overwatering , so if you are n’t sure , water less often than you call up you need to .
Do n’t use the old once - a - hebdomad chicken feed cube magic . For one thing , placing methamphetamine hydrochloride in the stack can damage any exposed source . And for another , that method acting does n’t take into account unlike environmental stipulation .
An orchid growing in bright morning sun with gloomy humidness is go to need urine more often than one place in a dark corner in a room with high humidity .
Eitheruse the bottom - watering techniqueor be sure to only apply water to the medium without splash it on the leaves . Awatering can stand for for use on houseplantswith a narrow nozzle can help .
Learn more about how to water orchidaceous plant in our guide .
If you really require to take on it good against etymon rot , which is common in orchids pot in territory ( and which is why it ’s always recommended that you repot them in bark ! ) , stress mounting your orchidaceous plant in moss on a patch of wood . It ’s almost impossible to overwater a mounted orchid .
Fertilizing
While orchid are n’t weighty feeders , they do need unconstipated fertilizing . They ’ll need more food for thought during the phase when they ’re developing flowers and when they ’re flowering .
Do n’t fertilise for at least the first calendar month or two after you bring your orchid home . Chances are near that your orchid was already blooming when you bought it .
This typically happens because raiser give the plant endocrine to force them to flower even if they typically would n’t at that prison term of year .
Overfeeding can stimulate problem , but a fiddling underfeeding wo n’t hurt anything .
Once it ’s time to start feeding , choose a soft , balanced plant food and feed your plant once every two weeks or so .

I affirm by Dr. Earth ’s Pump & rise fertilizer . It ’s well - balanced and meek enough for unconstipated use .

Growing Tips
Pruning and Maintenance
Repotting is a necessary part of regular maintenance and needing to do it is a sign that you ’re doing a not bad job raising your orchid .
It ’s growing and inflate because it ’s happy ! You ’ll know it ’s time for an ascent when you start to see origin come in out of the hole in the pot .
When I say “ start , ” I mean it . You have just a few weeks from the time when root tips first emerge from the holes to repot . After that , repotting will generally induce more hurt than undecomposed .
That means you take to ascertain your orchid regularly for Modern antecedent growth .
It typically happens in the spring and summertime , but that does n’t mean you could just go ahead and slack off in fall and winter . Keep an optic on your plant and check in on a regular basis at all fourth dimension of year !
metal money that are unremarkably available for sale typically settle in good order before they flower .
MostCattleyaspecies bloom either in December and January or March through May , though some species may blossom at other time throughout the year .
But some root right after flower , and a rare few may settle down at any old time , includingC. nobilior , C. aclandiae , C. violacea , andC. walkeriana . However , all miscellanea put on raw root growth for just a abbreviated period rather than doing so ceaselessly throughout the year .
If you miss the point when the origin are growing , wait until the next year to repot , and keep a close eye on affair . A year of being a bit rootbound is fine .
Once those roots start grow again , whether they ’re already sticking out of the holes or just starting to horn in out , it ’s time to get going .
Do n’t concern about anyroots growing above the soil . These aerial roots are different from the ones in the sensitive and they ’re not a augury that you need to exchange the container .
To repot , pluck the plant out of its existing container and brush off all of the spiritualist . Then , swerve off any decayed , kitschy , or wiped out roots .
Moisten the unexampled pot sensitive and compact some around the roots . Place the plant in a young pot just one sizing up from the previous one and fill in with more potting medium .
If you ’re farm a bifoliate plant , be aware that they do n’t care to be repot and you might notice stunted growth for a few months . You should wait a small longer in between repotting with these species .
For more steer , scan our complete guide to repotting orchids .
WhilePhalaenopsisorchids need carefully - check temperature toencourage reblooming , Cattleyaspecies will rebloom once a year so long as they receive enough light , and vice - versa – if they do n’t get enough Christ Within they wo n’t rebloom .
Once the blossom are spent , slew off the blossom spikeand its bud case with a blank tongue or scissors . The bud sheath is a leafage - comparable structure that surrounds the grow bloom . It sit just below the bloom but above the pseudobulb .
After the bloom emerge , bloom , and disappearance , the bud case has done its job and it wo n’t grow more peak .
Species to Select
Unless you shoot the breeze a serious hobbyist ’s show or a memory board that specializes in strange orchids , most cattleyas that you ’ll recover in stores are going to be gentle to grow .
In general , hybrids tend to be easier to civilise than unbent mintage .
For case , ‘ Grand Catherine , ’ ( Orglade ’s Grand x Hsinying Catherine ) is a crossbreed that has been bred from other hybrids to produce an unfussy cattleya that just about anyone can rise .
And the white flower petal with ruffled , magenta lips are very striking .
‘ Grand Catherine ’
If you ’d wish to get down your cattleya journey with a near - sure thing , pick up this hybrid cultivar in a five - inch potat Amazon .
AvoidC. dowiana , C. harrisoniana , andC. aclandiaeif you ’re a founding father . They ’re more thought-provoking , in damage of what they need to thrive .
The come after metal money , on the other hand , are recommended for anyone who wants to give cattleyas a endeavor .
Amethystoglossa
I have a cushy place for the amethyst - lipped orchidaceous plant . It was the first of theCattleyagenus that I ever owned and it was one of the gentle I ’ve ever cared for . It bloomed on a regular basis and prolifically .
This species is often confused withC. guttata , and they expect super similar . They ’re both bifoliates butC. guttatablooms in the summertime andC. amethystoglossablooms in winter .
The white , pink , and/or purple flowers are freckled except for the bottom petals , which are a single , solid color . ‘ Crownfox ’ is especially pretty , with pink blossoms splotch in Battle of Magenta .
Kerrii
This bifoliate metal money flush in April and May with clear majestic blossoms . MostC. kerriiplants have a vivid chicken splodge on the downcast petal .
The flower tend to be small and more narrow than those of other specie , and these plants can tolerate a bit more light .
Maxima
Themaximaspecies includes some gorgeous cultivars and hybrid .
Most feature some amount of purple or pink on large , narrow petals . The lower petal may be yellow , with splotch or veins in darker shadiness of pink or purple .
There is a white smorgasbord ( alba ) , and thecoeruleavariety has striking royal flowers .
C. maximaplants are unifoliate and bloom sometime from recent summer to wintertime . ‘ Blue Sky ’ is a particularly gorgeous cultivar , with pale bluish - purple blossoms .
Trianaei
As one of the species that was so popular in the ‘ 50s , along withC. labiataandC. mossiae , it could be found in homes and on articulatio radiocarpea across the US at the fourth dimension .
While they ’re not as democratic as they used to be , some incredibleC. trianaeihybrids and cultivar were bred during their heyday that still appear in stores today .
This is a unifoliate species that blossom in wintertime , right around the holidays .
The top petal tend to be either paler than or the same color as the bottom petal , which usually has dark , contrasting veins and a lily-livered center .
Walkeriana
A bifoliate , Walker ’s orchid allow for long - live on blossoms from late winter through spring .
The petal are broad and large , and the available colors lay out from near blue to purple , bright pink , and even white .
Managing Pests and Disease
Cattleyas are n’t immune toany of the pestsand diseases that may also impact other orchids .
Scale is the figure one trouble that you might confront . If you are n’t conversant with these common pests , read our guideto learn all about identifying and eliminating them .
You might also run acrossmealybugs , which are pretty similar , both in terms of designation and treatment . Thripsmay also get problem , though less ordinarily .
The top diseaseyou may run into is ancestor rot , which is far more rough-cut in cattleyas growing in soil . Those cultivate in a average consisting of orchid barque are less potential to suffer from root rot , which is cause by the oomycetesPythium ultimumandPhytophthora cactorum .
Crown rot is another problemthat has interchangeable symptoms .
It causes disastrous spotting , and the source turn black and mushy . Eventually the plant wastes aside and conk .
Lately , I ’ve been talk the kudos of Mycostop . It has saved a seriously sickMonstera‘Albo ’ of mine and a very unhappyPhilodendron gloriosumthat a friend gave up on and send my way .
It ’s extremely in force againstPythiumandPhytophthorapathogens .
