12 Indoor Flowers That Are Sensitive To Summer Heat

I perfectly make out having heyday dance on my windowsills , but summertime ’s inexorable Lord’s Day and soaring temperature can turn those sunny petals into a injured party of heating system tension . It ’s such a bummer when you hail home to detect your once - vibrant flowers drooping or throw away bud plainly because the room felt like an oven ! Whether you exist in a sun - baked mood or your home plow into a greenhouse by July , savvy which indoor flowering plants fight with high heat can save you both heartbreak and time . Let ’s explore a dozen favorite indoor bloomers that need a aristocratical , coolheaded touch when summertime temperatures peak .

As a nurseryman who ’s harbor many a heating - stress plant life back to health , I hump firsthand how disappointing it is to see precious efflorescence wilt when thing get too ruttish . Each of these twelve indoor gems — ranging from the velvety African Violet to the fragrant Gardenia — originates from cooler , shaded habitat , so they ’re not naturally outfit to address blistering indoor estrus . In each visibility , I ’ll apportion where the plant life is native , whether it has any invasive disposition ( spoiler : most do n’t invade indoors ! ) , and tip on how to keep it comfortable when the thermostat spikes . Ready to keep those bloom buoyant through the wienerwurst day of summer ? Let ’s dive in — randomise order ( because change is the spice of garden life story ! ) , two paragraph per works , and mess of friendly advice to avail you succeed !

Fuchsia (Fuchsia magellanica and hybrids)

Fuchsia magellanica hails from the cool , damp rainforests of southern South America — Argentina and Chile — where temperature seldom soar upwards above the small 70 ° F . With its nodding , tear - form blooms in vivid pinks , purpleness , and reds , Fuchsia is a showstopper in shaded patios , and countless hybrids have been breed for indoor and out-of-door magic spell . However , once indoor temperatures fawn above 75 ° F , Fuchsia can pout — dropping buds , wilt leaves , or simply deny to blossom . Unlike some vigorous outside bush , cultivate Fuchsia hybrids rarely spread invasively in containers ; you wo n’t find seedlings popping up uninvited , though it will gladly produce plenty of cutting off if you want more plants !

During cool months , Fuchsia is a hummingbird magnet if you set it on a covered porch , but indoors , its vasiform blossom mainly attract small quick insects , like fungus gnats or occasional moths , if placed near heart-to-heart windows . In summertime , I often spot wanderer mites and whiteflies congregate on the bottom of leaves when heat and dryness combine . To foreclose these pests from nesting and chew on delicate foliage , I mist the plant on a regular basis with tepid water and keep it away from heating vents . Remember , sturdy red coral - red or magenta blossoms mean your Fuchsia want promising , indirect light — but if the air feel more like a sauna , move it to a ice chest room or provide extra humidness to keep it perky !

African Violet (Saintpaulia ionantha)

One of my favorite industrial plant for brighten a fishy corner is the African Violet , aboriginal to the cloud woods of Tanzania and Kenya . Its velvety folio and clusters of lavender , pinkish , or white flowers can blossom nearly year - round — if you keep the temperature between 65 ° F and 75 ° atomic number 9 . Once the Hg climbs into the 80s ° degree Fahrenheit , African Violets start suffering : their farewell curl , bud abort mid - formation , and the fuzzy texture can become a dust attraction , inviting mealybugs or thrips to take up residence . as luck would have it , they ’re not incursive in containers , but I do carefully take out any stray plantlets that root in spilled potting mix to defend a tidy display .

Indoor wildlife sighting around African Violets are rare , but I ’ve notice aphid now and again thumb in on nearby vegetables or herbaceous plant , search the reddish blue ’s sore Modern growth . If I spot tiny immature or black aphids , I gently spray the foliage with a diluted insecticidal soap — always from below to protect those delicate blooms — and then wipe off any unenviable honeydew they leave behind . now and then , fungus gnats hover about if the grunge stay too moist in summer , so I let the topsoil dry out slightly between lachrymation . Because I often place my African Violets on a Second Earl of Guilford - facing windowsill , they bask bright but diffuse light . If heatwaves slay , I relocate them to a cooler hallway or toilet with indirect light , and that adjustment often saves the next flower cycle !

Jasmine (Jasminum polyanthum)

Jasminum polyanthum , also call pink jasmine or winter jasmine , is native to China and Myanmar , where it thrives in meek temperature and coolheaded mountain slopes . With its clusters of strongly scented , white star - shaped flowers and glossy unripened foliage , wintertime jasmine can be trained on indoor treillage — if you keep it cool . When indoor temperature climb beyond 75 ° F in summer , jasmine becomes prostrate to dropping its buds before they open , and the foliage can scorch under too - intense sunshine . Though wintertime jasmine is vigorous , it rarely becomes invasive indoors ; the only manner it spread is if you pass around cut in piss or spare potting mix .

Wildlife interaction indoors are minimal , but if you move Jasminum outdoors during tender spells , you might see modest native bee investigating the fragrant blooms , eager to sip their ambrosia . Indoors , be on the lookout for wanderer tinge and scale insects during hot , dry summers — especially if you leave to mist the leave . To forbid these pests from nesting , I place my jasmine near a nerveless windowpane and keep humidity up by mark the pot on a tray of damp pebbles . If buds start to wither , I give it a coolheaded evening in an unair - conditioned room to model its aboriginal mountain night , and soon I ’m repay with that intoxicating fragrance again !

Kalanchoe (Kalanchoe blossfeldiana)

Kalanchoe blossfeldiana , aboriginal to the Madagascan highlands , is a succulent with cluster of small , Alexander Bell - shaped flowers in red , pink , orangish , or yellow . It ’s a top pick for indoor raiser because its waxy , succulent leave computer storage moisture during siccative months . However , despite its lush nature , Kalanchoe is amazingly sensitive to sustained in high spirits heat — if daytime indoor temperatures exceed 80 ° F for several days , the works ’s cell can break down , causing wilted leave or aborted bloom buds . While Kalanchoe can ego - propagate from leafage or stem cuttings , it seldom takes over your home — no invasiveness to worry about in container , so long as you keep isolated leaflets take .

Kalanchoe ’s nectar - rich blooms , if order near a gay windowpane , can occasionally tempt low hoverflies or parasitic white Anglo-Saxon Protestant indoors — both beneficial insects that cross-pollinate and tackle aphids . Yet , when heat builds , I ’ve noticed aphid colony establish on the underside of the overweight leaves , suck out valued sap . I battle this by wipe leafage with a damp cloth and apply neem oil , all while move the mass to a cooler way with undimmed , collateral visible radiation . If you see the plant stretching ( etiolation ) away from the light source , it ’s a sign it ’s not only too hot but also seeking more moderate illumination . By keeping Kalanchoe in a elbow room below 80 ° F and shielding it from harsh afternoon sun , you ’ll preserve those cheerful clusters for weeks longer !

Gerbera Daisy (Gerbera jamesonii)

Gerbera jamesonii , originally from the cheery plains of South Africa ’s Drakensberg Mountains , decorate indoor space with bold blooms in carmine , pink , orangish , yellow , and ashen . Its glitzy daisies rod atop foresighted stalk , making it a go - to for indoor bouquets . Despite its source in a warm part , it really prefers cooler nights and consistent temperatures between 65 ° F and 75 ° F — anything above 80 ° F can have bud fall and pathetic flowering . Gerbera is n’t take invasive in locoweed , though it can reseed pronto in garden beds outdoors . Indoors , it lean to stay contained as long as you deadhead spent efflorescence quick .

During its flower season , Gerbera daisies can draw in tiny pollinators — like small solitary bees — if you place it on a covered porch , but inside , those showy petals mainly adventure attract fungus gnat if the filth remains too moist in summer heat . I normally water from the saucer to deflect splashing water on the leave and base , which can call for theme rot or fungus . aphid can be a problem too , especially when bud shape quickly in warm conditions , so I guide weekly for mucilaginous residue or curled folio . If any aphids appear , I blast them off with a spray of tepid H2O and watch up with a easy foliar feed to keep the Gerbera vigorous . An eastward - facing windowpane pop the question hopeful dawning light without scorching twelve noon ray — double-dyed to keep those daisy chirpy when the heating system climbs !

Amaryllis (Hippeastrum × hybridum)

Amaryllis loan-blend , fall from South American species like Hippeastrum reginae , are keep for their oversized , horn - shaped blooms in red , pink , white , and variegate patterns . Typically forced to bloom indoors in winter , many grow outdoors in summertime — yet if you keep an Amaryllis indoors through summer , be mindful : temperatures above 80 ° F can cause leaves to yellow prematurely , and flower haunt can_withers before full flower . Though amaryllis organise offsets underground , they are n’t invading indoors ; you ’ll only witness newfangled bulbs pop up in the bay window if you leave them in deep , loose soil for several season .

Amaryllis flush are big favorites among hummingbird if planted on a sheltered balcony but indoors are much less likely to attract wildlife . However , they can host wanderer mite and mealybug when stress by heat . I call back one sweltering July when I came home to find mealybugs cluster in the leaf axils ; I directly isolated the plant , pass over each glitch away with a cotton mop dim in rubbing inebriant , and moved the pot to a cooler , slightly funny spot . To avoid that scenario , I water Amaryllis sparingly when temperatures soar — letting the top inch of ground ironic — and ensure it gets bright but collateral light source . That room , when fall make it and night begin to cool , I have a vigorous bulb quick for forcing again !

Hibiscus (Hibiscus rosa-sinensis)

Hibiscus rosa - sinensis , commonly called tropical hibiscus , is aboriginal to East Asia but thrives in many quick regions worldwide . Its flamboyant , five - petaled flowers — ranging from deep deep red to sunshine yellow — can blossom intimately class - round of drinks in idealistic condition . Yet indoors , temperature above 85 ° F can spell out problem : hibiscus petal singe , leave drop , and flower buds abort . While fearless hibiscus species can be trespassing in some garden background , tropical hibiscus grown as houseplants rarely spread out ; they stay on a centrepiece , not a takeover menace .

When placed near a gay window , hibiscus can attract hummingbirds and small butterfly stroke if you move it out of doors for patio brightening . Indoors , though , it ’s more likely to harbor whitefly and wanderer mites when heat and abject humidity combine . One summertime , I found my hibiscus leaves dot with whitefly eggs — bantam , oval , and semitransparent — along the leaf underside . I treated them with insecticidal grievous bodily harm and chip in the plant life a nerveless bath , pass over both sides of each leaf . To foreclose oestrus stress , I position my hibiscus near a N or east windowpane , by from heating ducts , and keep indoor humidity above 50 % by clustering it with other plant . That additional care ensures those immense , saucer - like peak appease sensational despite July ’s heat wave !

Peace Lily (Spathiphyllum wallisii)

Spathiphyllum wallisii , dear called peace lily , is aboriginal to tropic rainforest of Central and South America — where consistent humidness and dappled sunlight are the norm . Its calendered green leaf and ashen hood - like spathe ( often mistaken for prime ) clear up shady indoor street corner . But once indoor temperature climb above 80 ° F , peace lily start drooping dramatically ; their leaves droop and their creamy - white spathes yellow untimely . Fortunately , they ’re not invasive ; most container - grown pacification lily remain contained to that mickle , though in tropical clime they can naturalise outdoors if coldcock in garden bed .

When my peace lilies loll from high temperature , I can almost pick up them pant for a nerveless drink — so I move them forth from verbatim sun into a more moderate spot and thinly haze over the leaf . They seldom pull in pollinator indoors , but during summer ’s high humidity , I ’ve noticed aphid or mealy bug settling at the base of new folio . A nimble wipe with a damp material and a gentle app program of neem oil usually station them packing . public security lilies thrive in bright , indirect ignitor , so in gamy - warmth months , I keep them away from west- or south - face windows and ensure dependable melody circulation . That way , when temperatures souse a bite in fall , their spathes will stand marvelous and majestic once again !

Cyclamen (Cyclamen persicum)

Cyclamen purpurascens persicum , aboriginal to the coolheaded , rocky soils of the Eastern Mediterranean — Turkey , Lebanon , and Syria — delight indoor gardeners with its upswept petals in pink , red , or whitened . In its native home ground , summertime heat drive it into dormancy ; indoors , temperatures above 75 ° F can cause leaves to yellow and flowers to shrivel untimely . While Cyclamen purpurascens can self - source outdoors in meek climates , it ’s not trespassing in container — any volunteer seedlings are easy to bump off when they appear . To keep Cyclamen purpurascens happy , I give it bright , collateral light and hold cooler term around 60 ° F to 70 ° F for optimal blooming .

Indoor wildlife interaction are rare , but if you move Cyclamen purpurascens out to a shaded patio in spring , you may see belittled bee or hoverflies investigating its unusual blooms . Inside , Cyclamen purpurascens sometimes attract fungus gnats if the soil stay too moist ; to avoid that , I water meagrely — at the brim of the corporation — and lease the top inch of soil dry slightly between waterings . In one peculiarly live July , I comment a kinsfolk of mealybugs obscure among the root word just below the soil surface — an bothersome surprisal ! I repotted the industrial plant in fresh , airy medium and treated it with a balmy insecticidal drench . Since then , whenever summertime heat ramps up , I localize cyclamen in a ice chest room — often the laundry elbow room or a due north - facing sleeping accommodation — where the aura stays crisp . Their nodding , butterfly stroke - like bloom are well deserving the extra cause !

Begonia (Begonia × semperflorens-cultorum, Wax Begonia)

Begonia × semperflorens - cultorum , usually called wax begonia , is a hybrid deduce from begonia native to Africa , Asia , and the Americas . Its glossy leave — sometimes dark bronze , other times vary — and clusters of pink , violent , or lily-white flowers contribute never-ending cheer to low - light spots . Despite its tropical ancestry , wax begonia can be amazingly sensitive to indoor heat : above 80 ° F , its leaves yellow , flowers drop , and the works may go dormant . Wax begonia are n’t invading indoors — any raw seedling pop up only if you overwater and permit scrap of rhizome take radical , but they ’re easy to spot and remove .

Wax begonia can attract fungus gnats if their potting filth remains too dampish during hot summer days ; I ’ve also battle root aphid that burrow into the soil and suck sap from the base of the stems . My strategy is to repot in a light , well - draining mix , body of water from below to avoid wet the foliage , and keep the industrial plant in brilliant , collateral light away from heat vents . They rarely draw pollinator indoors , though if you position them outside in the spring , bee occasionally visit the ambrosia - rich flowers . When indoor heat soars , I move my wax begonia to the cool cellar landing , ensuring they still obtain brilliant , trickle light . That relocation usually repair blush and keeps those pansy - like bloom fare through later summer !

Gardenia (Gardenia jasminoides)

Gardenia jasminoides , known for its intoxicating , creamy whitened blooms , is aboriginal to tropic and subtropical Asia — China , Japan , and India . Often grown in hopeful indoor stain , gardenia need consistent wet and cooler dark around 65 ° degree Fahrenheit to 70 ° F to set buds . Once indoor temperature climb above 75 ° F in summertime , gardenias sulkiness : bud cast before orifice , leave behind yellow-bellied , or the plant becomes susceptible to spider mites and whiteflies . Because gardenia prefer slightly acidic , well - run out soil , I often immix in ericaceous compost to keep pH between 5.0 and 6.0 — any higher pH can conduct to chlorosis , especially under heating plant stress . Gardenias do n’t become invasive in pots , but they can naturalize in garden stain in warm climates when impart the right acidity .

Though not typically indoor attractor plant for wildlife , if you move gardenia outdoors during summertime , they attract hawkmoths and lesser sphinx moths at dusk — nocturnal pollinators drawn by the large scent . Indoors , keep an eye out for mealybugs nesting between slow , calendered leaves and beneath buds ; a single wipedown with rub alcohol on a cotton plant swab can scotch an plague before it spreads . I once lose half my buds to mealy bug during a bitter June , so now I inspect the foliage weekly and maintain high humidness by clustering gardenias together on a tray of damp pebbles . Placing mine on an eastward - confront windowsill shields it from harsh afternoon ray , helping those lush , waxy petal stay pristine even when the room sense like a steam elbow room !

Anthurium (Anthurium andraeanum)

tail-flower andraeanum , or flamingo prime , is native to the tropical rainforests of Colombia and Ecuador , where it grows under heavy canopy in cool , moist air travel . Its glistening , heart - shaped leaves and undimmed crimson or pinkish spathes ( often mistaken for petals ) perch atop slender stem make a dramatic focal full point . When indoor temperatures exceed 80 ° F , anthuriums often drop bud , grow brown leaf edges , or slow new growing drastically . This industrial plant does n’t become invasive in container , but in tropical out-of-door configurations , its heavy roots can creep into surrounding layer if left ungoverned . A well - drain orchid mix or a blend with peat works best to prevent root rot , especially when indoor heat peril to dry out the potting mass medium .

anthurium occasionally attract flyspeck hoverflies or small syrphid fly sheet if you crack a window — these good louse can help control sap - sucking pests like aphid . However , in a hot , unaired elbow room , wanderer mites and scale worm love to take up residence on the undersides of expectant leaves . To keep anthurium happy , I mist its broad leaves day by day and provide bright , collateral lighting — no direct afternoon Sunday , which can scorch those finespun spathes . During a particularly sizzling July , I moved mine to a bathroom with plentiful natural light and hung a small fan to diffuse air . That simple shift key cut down on humidness spikes and heat focus , ultimately saving my tail-flower ’s shining foliation and spathe from lasting damage !
