Houseplants that like high humidity are usually native to tropical or rainforest environments where the air is warm and moist. These plants are adapted to absorb moisture not just through their roots, but also through their leaves. Because of this, they tend to struggle in dry indoor air and thrive when humidity levels are higher.
Many popular indoor plants fall into this category, including ferns, peace lilies, and calatheas. These plants often have thin or broad leaves that lose moisture quickly, so they benefit from humid conditions that prevent drying out. In the right environment, they display lush growth and vibrant foliage.
High humidity helps these plants maintain healthy leaf structure and prevents issues like browning edges or curling leaves. It also supports proper growth and can even encourage flowering in some species. Without enough moisture in the air, these plants may appear dull or stressed over time.
There are several ways to increase humidity for indoor plants. Grouping plants together can create a mini humid zone, while placing them near a humidifier provides consistent moisture. Bathrooms and kitchens are also good spots, as they naturally have higher humidity levels.
Misting is sometimes used, but it offers only a temporary boost and may not be enough on its own. A more effective method is using a tray filled with water and pebbles beneath the plant pot, allowing moisture to slowly evaporate around the plant.
In general, houseplants that like high humidity reward proper care with rich, tropical-looking growth. By recreating a moist environment indoors, you can keep these plants healthy and enjoy their vibrant appearance throughout the year.

Plants That Decrease Humidity
Bird of Paradise (Strelitzia reginae)
The bird of paradise is a bold, tropical showstopper whose large, paddle-shaped leaves and extraordinary orange-and-blue flowers are a direct reflection of its origins in the humid subtropical regions of South Africa.
Indoors, it performs best when ambient humidity is kept consistently high, which prevents the leaf edges from browning and splitting — the most common sign that the air around this magnificent plant is far too dry.
Boston Fern (Nephrolepis exaltata)
The Boston fern is one of the most humidity-dependent of all common houseplants, and its long, arching fronds of bright green will begin to yellow and drop their leaflets with discouraging speed the moment the air around them becomes too dry.
It positively thrives in steamy bathrooms and kitchens, where the natural moisture in the air provides exactly the humid atmosphere its tropical origins demand.
Calathea (Calathea spp.)
Calatheas are famed for their intricately patterned, richly coloured leaves — striped, spotted, and feathered in combinations of green, purple, silver, and cream — but those spectacular markings come at a price: they are among the most humidity-sensitive of all foliage houseplants.
The leaf edges curl and crisp at the first hint of dry air, making a consistently humid environment not just beneficial but absolutely essential for keeping them looking their best.
Orchid (Phalaenopsis spp.)
Moth orchids are epiphytic plants that grow naturally anchored to the bark of trees in the warm, humid rainforests of Southeast Asia, where moisture-laden air surrounds their exposed roots at almost all times.
Indoors, replicating that humidity is one of the most important factors in keeping them healthy — it supports root vitality, prolongs the life of the blooms, and encourages the development of new flower spikes after the previous display has finished.
Monstera (Monstera deliciosa)
The iconic monstera, with its dramatic, fenestrated leaves, hails from the deeply humid understorey of Central American tropical rainforests, and it grows most vigorously when indoor humidity is kept well above the levels typically found in a heated home.
Regular misting, a pebble tray, or a nearby humidifier will reward you with larger, more dramatically split leaves and the kind of lush, fast growth that makes this plant so satisfying to own.
Peace Lily (Spathiphyllum spp.)
The peace lily is one of the most communicative of all houseplants — its leaves droop dramatically when it needs water and its tips brown visibly when the air is too dry.
As a native of the humid tropical forests of Colombia and Venezuela, it appreciates a consistently moist atmosphere and will reward good humidity levels with glossy, upright foliage and a more generous production of its elegant white spathes.
Anthurium (Anthurium andraeanum)
Anthuriums are tropical plants whose waxy, heart-shaped spathes in vivid red, pink, and white are among the most long-lasting of any flowering houseplant — but only when humidity levels are kept sufficiently high.
In dry air, the glossy leaves develop brown tips and the flowers lose their characteristic lacquered sheen, so placing an anthurium in a humid bathroom or near a humidifier makes a visible and immediate difference to its appearance and overall vigour.
Fiddle Leaf Fig (Ficus lyrata)
The fiddle leaf fig is a fashionable and dramatic indoor tree whose enormous, violin-shaped leaves are as demanding as they are beautiful.
Native to the lowland tropical rainforests of West Africa, where humidity is extremely high year-round, it suffers visibly in dry indoor air — the leaf edges brown, growth slows, and the plant becomes vulnerable to the spider mites that thrive in arid conditions and love nothing more than an already-stressed fiddle leaf fig.
Croton (Codiaeum variegatum)
Crotons produce some of the most extravagantly coloured foliage in the houseplant world, with leaves painted in startling combinations of red, orange, yellow, and green — but that vivid colouring depends heavily on the plant receiving adequate humidity alongside bright light.
In dry air, the leaves drop with frustrating speed and the brilliant colour palette fades, making a humid environment one of the single most important contributions you can make to keeping a croton at its spectacular best.
Nerve Plant (Fittonia albivenis)
The nerve plant is a low-growing, ground-hugging tropical from the rainforests of South America, where it lives in conditions of near-constant warmth and very high humidity beneath the forest canopy.
Its intricately veined, jewel-like leaves — traced in white, pink, or red — collapse dramatically and almost immediately in dry air, making it one of the most reliable indicators of insufficient humidity in a room and one of the most rewarding plants to grow inside a glass terrarium.
Rubber Plant (Ficus elastica)
The rubber plant is a vigorous indoor tree from the humid tropical forests of South and Southeast Asia, and while it is considerably more tolerant of indoor conditions than many of its tropical counterparts, it grows most lushly and develops its finest, most glossy foliage in a humid environment.
Regular wiping of the large leaves removes dust and supports their ability to absorb moisture from the surrounding air — a simple practice that makes a noticeable difference to the plant’s appearance and health.
Parlour Palm (Chamaedorea elegans)
The parlour palm is one of the most elegant and adaptable of all indoor palms, capable of tolerating lower light than most, but genuinely thriving when it is also given the warm, moist air that its Central American jungle origins call for.
In humid conditions its slender, arching fronds remain a deep, lustrous green without the browning tips that are the signature complaint of parlour palm owners who keep them in centrally heated rooms with very dry air.
Zebra Plant (Aphelandra squarrosa)
The zebra plant is a dazzling, attention-commanding houseplant with large, dark green leaves boldly striped with ivory-white veins and dramatic yellow flower bracts that rise from the centre of the plant like a torch.
It is also one of the most humidity-demanding of all indoor plants, originating from the wet, tropical forests of Brazil, and it will drop its leaves rapidly and without much warning if placed in a dry, draughty, or centrally heated room.
Bird’s Nest Fern (Asplenium nidus)
Unlike the more feathery fern varieties, the bird’s nest fern produces broad, entire, glossy fronds that unfurl in a rosette from a central nest-like crown, giving it an almost tropical, architectural quality.
It thrives in the warm, steamy humidity of a bathroom environment and rewards consistently high moisture levels with fronds that are wide, smooth-edged, and a deep, satisfying shade of bright green, in contrast to the narrow, crinkled fronds produced under drier conditions.
Philodendron (Philodendron spp.)
Philodendrons are vigorous, tropical foliage plants with origins in the humid rainforests of Central and South America, and whether trailing, climbing, or growing as bold, upright specimens, they share a genuine appreciation for warm, moist air.
High humidity encourages the production of larger, more dramatically shaped leaves — particularly important for the split-leaved and velvety varieties that are currently so popular — and helps prevent the browning leaf margins that signal air that is too dry for their liking.
Dracaena (Dracaena spp.)
Dracaenas are among the more tolerant of tropical houseplants, but they still show a clear preference for humid conditions over the parched air of a centrally heated home.
Their long, strap-like or sword-shaped leaves develop brown, papery tips in dry atmospheres — a widely recognised problem with this popular genus — and a modest increase in ambient humidity, whether through misting or a humidifier, goes a long way towards keeping the foliage clean, green, and tip-free.
Chinese Evergreen (Aglaonema spp.)
Chinese evergreens are deservedly popular as low-maintenance, low-light houseplants, but their lush, patterned foliage — which ranges from deep green through silver, pink, and red depending on the variety — looks its most vibrant when humidity is kept at a comfortable level.
In very dry air, the beautifully variegated leaves begin to brown at the tips and margins, gradually losing the crisp, colourful appearance that makes aglaonema one of the most decoratively rewarding of all indoor foliage plants.
Pothos (Epipremnum aureum)
Pothos is one of the toughest and most forgiving houseplants available, capable of surviving neglect and poor conditions that would finish off more sensitive species — but it rewards higher humidity with noticeably more vigorous, lusher trailing growth and larger, more richly coloured leaves.
In genuinely humid conditions, such as a bathroom shelf, the variegated forms in particular develop their cream-and-green or golden markings with greater intensity and clarity.
Begonia (Begonia spp.)
The begonia family encompasses an enormous range of forms — from the wax begonia with its cheerful flowers to the extraordinary rex begonia with its fantastically patterned, metallic-sheen foliage — but virtually all of them share a preference for warm, humid growing conditions.
High humidity supports both vigorous foliage development and prolific flowering, and it is particularly critical for the rex varieties, whose papery, intricately textured leaves are especially prone to crisping in dry air.
Pitcher Plant (Nepenthes spp.)
Tropical pitcher plants are among the most extraordinary of all houseplants, producing hanging, liquid-filled pitchers from modified leaf tips that trap and digest insects to supplement the nutrients absent from the very poor soils of their native rainforest habitat.
That same rainforest origin means they demand very high humidity as a non-negotiable growing condition — without it, the pitchers fail to develop properly, the leaves yellow, and the plant declines rapidly, making a terrarium or a heated, humid greenhouse the most reliably successful home for these remarkable carnivores.
Maidenhair Fern (Adiantum spp.)
The maidenhair fern is widely considered the most beautiful and also the most unforgiving of all ferns commonly grown as houseplants. Its clouds of tiny, fan-shaped leaflets carried on delicate, wiry black stems are breathtakingly delicate in appearance — and equally delicate in their requirements, demanding exceptionally high humidity at all times.
Even a few hours in dry air can cause the fronds to brown and shrivel irreversibly, making it best suited to a steamy bathroom, a glass case, or the company of a dedicated owner willing to provide the consistently moist atmosphere it absolutely cannot do without.
Spider Plant (Chlorophytum comosum)
The spider plant is one of the most adaptable and widely grown houseplants in the world, tolerating a remarkable range of indoor conditions with cheerful resilience — but it rewards consistent humidity with noticeably lusher, more vibrant foliage and longer, more generously furnished trailing runners. In dry air the leaf tips brown reliably and quickly, a problem so common with spider plants in heated homes that many owners assume it is inevitable, when in reality it is simply a consistent signal that the air around the plant needs more moisture.
Weeping Fig (Ficus benjamina)
The weeping fig is a graceful indoor tree with small, glossy, oval leaves on elegantly drooping branches that can reach impressive heights indoors over many years — but it is also one of the most temperamental of all commonly grown houseplants, dropping leaves dramatically in response to any environmental change it dislikes, including dry air.
Consistent humidity, alongside stable temperatures and a fixed position away from drafts, is one of the most important contributions to keeping a weeping fig settled, leafy, and growing contentedly rather than perpetually shedding in protest.
Alocasia (Alocasia spp.)
Alocasias are spectacular tropical foliage plants with large, dramatically shaped, arrow or shield-shaped leaves in combinations of deep green, silver, and near-black that make them among the most architecturally impressive of all indoor plants.
They originate from the humid tropical forests of Southeast Asia and demand consistently high humidity to maintain the glossy, turgid leaf surfaces that make them so striking — in dry air the leaf edges brown and the plant becomes vulnerable to spider mite infestations, which are among the most damaging pests for this already sensitive genus.
Stromanthe (Stromanthe spp.)
Stromanthe is a close relative of the calathea and prayer plant, sharing their preference for warm, humid conditions and their extraordinary foliage coloring — with the Triostar variety in particular producing leaves boldly variegated in pink, cream, white, and green that make it one of the most colorful foliage houseplants available anywhere.
In dry air the cream and white variegated areas of the leaves brown and crisp at the margins with particular speed, and the vivid pink coloring fades noticeably, making adequate humidity one of the most important factors in maintaining the spectacular appearance this plant is grown for.
Ctenanthe (Ctenanthe spp.)
Ctenanthe is another member of the prayer plant family with long, lance-shaped leaves boldly patterned in silver, green, and cream on the upper surfaces and vivid purple-red on the undersides, sharing the family characteristic of folding its leaves upward at night.
Like its calathea and stromanthe relatives, it is sensitive to dry air and will develop browned, crisped leaf margins rapidly when ambient humidity falls below comfortable levels, making it best suited to naturally humid rooms or positions near a humidifier where moisture levels remain consistently adequate.
Tradescantia (Tradescantia spp.)
Tradescantia, commonly known as Wandering Dude or Spiderwort, is a fast-growing trailing plant with oval, slightly fleshy leaves in combinations of green, purple, and silver that is considerably tougher than most humidity-loving houseplants — but it still produces its most vivid coloring and most vigorous trailing growth in conditions of reasonable ambient moisture.
In very dry air the leaf tips and margins brown and the vivid purple coloring of varieties like Tradescantia zebrina fades noticeably toward green, losing the striking metallic sheen that makes these plants so visually appealing in good growing conditions.
Columnea (Columnea spp.)
Columnea, sometimes called the Goldfish Plant, is a trailing epiphytic gesneriad from the humid tropical forests of Central and South America, producing long, cascading stems densely clothed in small, fleshy, dark green leaves and vivid red, orange, or yellow tubular flowers that genuinely resemble small leaping goldfish.
It requires consistently high humidity to perform well indoors, as the trailing stems and densely packed leaves are susceptible to desiccation in dry air, and adequate moisture is one of the most critical factors in encouraging the plant to produce the prolific flower display it is capable of under good conditions.
Episcia (Episcia spp.)
Episcias are low-growing, spreading gesneriads with wonderfully textured, iridescent foliage in combinations of copper, silver, green, and bronze, and small but vivid tubular flowers in red, orange, yellow, and pink that add color interest above the already ornamental leaf display.
They are humidity-demanding plants that originate from the forest floors of tropical South America, and in dry air the beautifully textured, metallic-sheen leaves lose their iridescence, brown at the margins, and the plant rapidly loses the lush, spreading habit that makes it so attractive as a trailing or ground-covering houseplant.
Peperomia (Peperomia spp.)
Peperomias are a vast and diverse group of semi-succulent tropical foliage plants that are generally more tolerant of lower humidity than many tropical houseplants — but the most ornamental, thin-leafed varieties with delicate variegation or intricate surface textures still perform noticeably better in conditions of moderate to good ambient humidity than in the very dry air of a centrally heated home.
Varieties with thicker, more succulent leaves such as the Watermelon Peperomia and Baby Rubber Plant are the most drought and dry-air tolerant within the group, while thinner-leafed trailing types benefit more meaningfully from additional moisture in the air.
Hoya (Hoya spp.)
Hoyas are semi-succulent trailing and climbing plants with waxy, fleshy leaves and clusters of intensely fragrant, star-shaped flowers that are among the most rewarding of all flowering houseplants for patient growers — and while their succulent nature makes them more drought and dry-air tolerant than most tropical plants, consistent moderate humidity encourages the production of the flower clusters that are the primary reason most collectors grow them.
In very dry, heated indoor air the flower clusters are less freely produced, the older leaves lose some of their characteristic waxy sheen, and the plant’s overall vigor is noticeably reduced compared to specimens grown in more humid conditions.
Fittonia (Fittonia spp.)
Fittonia, more widely known as the Nerve Plant, is a compact, ground-hugging tropical plant whose intricately veined, jewel-like leaves in combinations of deep green traced with white, pink, or red veining make it one of the most visually detailed and ornate small foliage plants available.
It is extraordinarily sensitive to dry air, wilting and collapsing within hours of humidity dropping below comfortable levels — a behavior so pronounced and rapid that experienced plant owners call it the fainting plant — and it is most successfully grown inside a glass terrarium where near-constant high humidity is naturally maintained by the enclosed environment.
Calathea Orbifolia (Calathea orbifolia)
Calathea Orbifolia is one of the most spectacular members of the calathea family, producing enormous, round leaves up to 12 inches across boldly banded with wide alternating stripes of silver-green and darker green that create a graphic, almost architectural foliage effect.
It is among the most humidity-sensitive of all calatheas, requiring consistently high moisture levels in the air to maintain the smooth, turgid leaf surfaces and clean leaf margins that make it so beautiful — in dry conditions the large leaf surface area accelerates moisture loss, and the leaf edges brown and curl with particular speed and severity compared to smaller-leafed calathea varieties.
Spathiphyllum Sensation (Spathiphyllum ‘Sensation’)
Spathiphyllum Sensation is the giant form of the standard Peace Lily, producing dramatically large, deeply ribbed, glossy dark green leaves that can reach 20 inches or more in length on a plant growing to 4 to 5 feet in height — making it one of the most architecturally impressive of all flowering tropical houseplants.
Like the standard peace lily, it is native to the humid tropical forests of Colombia and Venezuela and requires consistently moist air to maintain the glossy, turgid appearance of its large leaves and to encourage the reliable production of its elegant white flower spathes throughout the year.
Maranta (Maranta spp.)
Maranta, the true prayer plant, produces oval, velvety leaves with some of the most intricately beautiful patterning of any houseplant — including the classic red-veined Herringbone variety with its vivid red veining on a rich green and pale green two-tone background — and it folds its leaves upward in a praying motion each evening in a display of nyctinastic movement that never loses its charm.
It requires warm, consistently humid conditions to maintain the velvety texture and rich color saturation of its patterned leaves, and in dry air the leaf margins brown and the velvety surface takes on a dull, papery quality that considerably diminishes its ornamental appeal.
Syngonium (Syngonium spp.)
Syngonium, also called Arrowhead Plant, is a versatile tropical foliage plant with arrow-shaped leaves in combinations of green, cream, pink, and bronze that adapts well to a range of indoor conditions but grows most vigorously and produces its most richly colored foliage in warm, humid environments that mirror its native Central American rainforest habitat.
In very dry air the pale, cream, and pink-toned variegated varieties in particular develop browning margins that detract significantly from their ornamental appeal, and the plant’s natural tendency to trail or climb is most exuberantly expressed in conditions of good ambient humidity.
Heliconia (Heliconia spp.)
Heliconias are bold, tropical plants with enormous, banana-like paddle-shaped leaves and extraordinarily dramatic, waxy flower bracts in vivid combinations of red, orange, yellow, and green that make them some of the most spectacular tropical flowering plants grown in warm indoor and conservatory environments.
Native to the wet, humid tropical forests of Central and South America, they are non-negotiably demanding of very high humidity and warmth, and without consistent moisture in the air the large leaf surfaces desiccate rapidly, the foliage browns extensively, and the plant fails to produce the extraordinary flower bracts that are its most compelling ornamental feature.
Strelitzia Nicolai (Strelitzia nicolai)
The Giant White Bird of Paradise is a large, dramatic indoor tree producing enormous, paddle-shaped leaves up to 3 to 4 feet in length on tall, upright stems that can reach 6 to 8 feet or more indoors, creating one of the most architecturally impressive houseplants available for large spaces.
Like its smaller relative the standard Bird of Paradise, it originates from subtropical South Africa and benefits greatly from consistent ambient humidity, which prevents the characteristic splitting and browning of leaf edges that is the most universally recognized sign of a Giant Bird of Paradise struggling in air that is too dry for its needs.
Schefflera (Schefflera spp.)
Schefflera, commonly known as the Umbrella Plant, produces distinctive whorls of long, glossy, oval leaflets radiating from the tips of upright stems like the spokes of an open umbrella, creating a bold and architectural indoor tree that can reach impressive heights in large, well-lit rooms.
While it is more tolerant of average indoor conditions than many tropical houseplants, consistent humidity encourages the production of larger, glossier, more deeply colored leaflets and helps prevent the spider mite infestations that are the most common pest problem on scheffleras grown in dry, heated indoor environments.
Dieffenbachia (Dieffenbachia spp.)
Dieffenbachia, or Dumb Cane, is a large, bold foliage plant with broad, oval leaves patterned in striking combinations of cream, white, green, and yellow that make it one of the most visually dramatic of all commonly grown tropical houseplants.
It originates from the humid tropical forests of Central and South America and grows most vigorously in consistently warm, moist conditions, with adequate humidity supporting the production of large, turgid, richly patterned leaves — in dry air the leaf margins brown and the large leaf surface area accelerates moisture loss, causing the foliage to lose the crisp, lush quality that is its primary ornamental asset.
Bromeliads (Bromeliaceae family)
Bromeliads are a spectacularly diverse family of tropical plants that includes species naturally adapted to absorb moisture through their leaves and the central water-holding cups formed by their rosette of leaves — a characteristic that reflects their epiphytic, moisture-dependent origins in the humid forests of tropical South America.
While the central cup should always be kept filled with water as the primary moisture source, consistent ambient humidity around the leaves supports overall plant health, encourages the development of more vibrant leaf coloring, and helps maintain the long-lasting, colorful flower bracts that are the most spectacular ornamental feature of the most commonly grown bromeliad varieties.
Tillandsia (Tillandsia spp.)
Tillandsias, or Air Plants, are among the most extraordinary and unusual of all plants grown indoors, requiring no soil whatsoever and absorbing all the water and nutrients they need directly through specialized scales on their leaf surfaces called trichomes.
Because the leaves are their sole moisture-collection organ, adequate ambient humidity is not merely beneficial but absolutely essential to their survival — in very dry indoor air, even regular misting fails to compensate adequately for the lack of environmental moisture, and the leaf tips brown and curl progressively as the plant slowly desiccates from the outside in despite the grower’s best efforts.
Cissus (Cissus spp.)
Cissus, sometimes called Grape Ivy or Kangaroo Vine, is a vigorous trailing and climbing houseplant with attractively lobed or divided leaves that grows rapidly and tolerates a wider range of indoor conditions than many tropical plants — but it performs most impressively in conditions of good ambient humidity where the trailing stems produce larger, more richly colored leaves and grow with considerably more vigor and enthusiasm than in dry, heated room air.
The most ornamental varieties including the rex begonia vine and the Cissus discolor with its iridescent, silver-marked foliage are considerably more humidity-sensitive than the tougher standard grape ivy forms.
Caladium (Caladium spp.)
Caladiums are grown almost exclusively for their extraordinarily beautiful, papery-thin, translucent leaves in vivid combinations of white, pink, red, and green that make them among the most spectacularly colorful of all foliage houseplants during their active growing season.
The very thinness of the leaves that makes their coloring so luminous and beautiful also makes them exceptionally vulnerable to dry air, which causes them to wilt, brown, and deteriorate with great speed in conditions of insufficient humidity — making a consistently warm, moist environment one of the most critical requirements for keeping these spectacular plants looking their best throughout the growing season.
Colocasia (Colocasia spp.)
Colocasia, commonly known as Elephant Ear or Taro, is a bold, tropical foliage plant with enormous, heart-shaped to arrow-shaped leaves that can reach 2 to 3 feet in length on vigorous specimens, creating one of the most dramatically large-scale foliage displays possible in an indoor or conservatory setting.
Native to the wet, humid tropical and subtropical regions of South and Southeast Asia, it demands consistently high humidity and generous watering to maintain the turgid, deeply colored, impressively large leaves that are its defining ornamental characteristic — in dry air the enormous leaf surface area accelerates moisture loss rapidly, causing the foliage to wilt, yellow, and brown at the margins with discouraging speed.
