When temperatures drop and it's time to turn on the heating, Keeping the house warm becomes a priorityBut often, that seems to clash with having healthy plants indoors. Hot air dries out the environment, lowers humidity, and if the temperature is too high, some species suffer and end up dying. Even so, there's no reason to give up on that touch of greenery that brings life to any living room or bedroom.
The good news is that There are plants you can have in winter. These plants are capable of withstanding central heating and the dry conditions typical of winter. Many have proven their resilience for years in offices, building entrances, shops, and homes with radiators running almost all day. Knowing which ones they are, how they perform in the cold season, and what minor care they require is key to enjoying a comfortable home filled with greenery, even during the harshest months.
How does heating affect indoor plants?
Before rushing out to buy flowerpots, it's important to understand that Heating does more than just provide heatIt also significantly reduces the relative humidity of the air. That dry air It causes the leaves to dehydrate faster, promotes the appearance of brown tips, and can cause the substrate to take longer to balance its moisture, with the consequent risk of stress for the plant.
Furthermore, In winter there are fewer hours of natural light And ventilation is often poor because we open the windows less often. The combination of low light, dry air, and sudden temperature changes (for example, when turning the heating on and off) is lethal for many delicate species. That's why it's so important to choose varieties accustomed to indoor environments and some irregularity in conditions.
Another point to keep in mind is that Not all heating systems affect plants equally.Central heating with radiators tends to dry the air, but it does so more evenly and gently. In contrast, hot air appliances that blow directly (such as heat pumps or fan heaters) are much more aggressive, both due to the high temperature of the air stream and the speed at which they remove ambient humidity.
In any case, most of the species we will see below have in common that They tolerate moderate heat and relative dryness wellProvided they aren't placed directly next to a heat source and receive adequate light, many ficus, sansevieria, and cacti thrive in offices with strong heating and few windows, which is a significant advantage at home.
Indoor plants that can withstand heating in winter
When choosing, it is essential to be clear that the specific conditions of each dwelling Factors such as heating type, room size, orientation, number of plants, and ventilation greatly influence the behavior of each plant species. A spacious living room with low-temperature radiators and large windows is not the same as a small bedroom with a heat pump pointing directly at the potted plants.
Therefore, rather than thinking of a closed list, It is advisable to know which plant families are best adapted This environment includes: species of tropical origin accustomed to indoor environments, cacti and succulents that tolerate dryness very well, and some classic indoor varieties that have been demonstrating their resilience in heated public and private spaces for years.
Bonsai
Bonsai trees are small trees grown in very small potsThis already makes them sensitive to changes in humidity and temperature. However, certain bonsai species thrive in heated indoor environments, provided that varieties adapted to this use are chosen and a consistent care routine is maintained.
The key is in consult a nursery or specialized center Which bonsai species thrive best indoors with central heating? Not all are suitable for indoors: some need to spend the winter outdoors to respect their dormancy period. Among the most common indoor bonsai are ficus trees or some tropical species that tolerate stable temperatures around 18-22°C.
In a heated home, the most delicate thing for a bonsai is avoid dehydration of the substrate and leavesIt's important that it never receives direct hot air, that it's kept at a distance from radiators or stoves, and that you monitor its watering frequently, checking the soil moisture with your finger. A couple of gentle mistings a week, if the environment is very dry, will also do it wonders.
Narrow-leaved palm trees
Among the indoor palm trees, the varieties with fine and delicate leaves They tend to adapt better to the dry, warm environments typical of heated homes. Examples like the Chamaedorea elegans (the classic parlor palm) tolerate a lack of humidity quite well and are perfect for adding an exotic and airy touch to the living room or entryway.
These compact and elegant palm trees They prefer plenty of light but not direct sunlight.In winter, it's advisable to place them near a bright window, but out of direct midday sun. At the same time, keep them away from heating appliances, as the direct airflow can burn the tips of the leaves and leave them looking straw-like.
If there are cats or other pets at home, you should consider that Some palm trees can be very tempting for them to nibble on.This constant nibbling prevents the leaves from growing properly and leaves the plant looking unhealthy. In these cases, a good idea is to place the palm tree indoors, but out of the animal's reach, and add a special pot with cat grass or edible seeds so the feline can have its own "little plant" without destroying the rest.
Pothos or pothos (Epipremnum aureum)
The poto is one of the hardier hanging and climbing plants There are varieties available for indoors. It's accustomed to living with heating, dry air, and some lack of light, making it a safe bet for those who want greenery at home without too much hassle. Furthermore, it grows quickly and allows you to create cascades of beautiful leaves on shelves and tall furniture.
Within the broad group of plants similar to the pothos, Many decorative vines perform very well in winter Inside climate-controlled homes, they only need indirect light (near a window, but without intense direct sunlight) and the substrate should be kept slightly moist, avoiding waterlogging which could rot the roots during periods of lower evaporation.
One of the great advantages of pothos is that It tolerates occasional watering lapses well.If we go away for a few days or forget to water it, it usually recovers easily as soon as we resume our routine. However, it's best to avoid direct hot air on the leaves, as this can worsen dehydration and cause some to turn yellow.
Cacti and other succulents
When you're looking for a really simple solution, Cacti and succulents take the cakeThey are adapted to withstand both high temperatures and the extreme dryness typical of arid climatesThis is precisely what we find in many homes with central heating running for several hours a day. The only critical factor is overwatering, especially during the colder months.
Create small arrangements with different cacti in a tray or in a large pot. It's a quick way to introduce a natural touch In the living room, office, or even the kitchen. They don't require misting, high humidity, or fertilizer in winter. Just plenty of light (ideally near a window) and infrequent watering, allowing the soil to dry out completely between waterings.
Precisely because of that capacity to store water, The danger in winter is over-wateringSince water evaporates more slowly in cold weather, watering as you would in summer can cause root rot. It's best to reduce watering frequency to a minimum, especially if the heating isn't too strong and the soil temperature remains cool.
Indoor Ficus
The ficus, in its many varieties (such as Ficus benjamina or Ficus elastica), is one of the great classics of heated public spacesOffices, building entrances, shopping centers… That already gives us a clue about their hardiness. These shrubby plants or small trees adapt very well to living indoors year-round with stable temperatures, provided they have enough light.
At home, Any type of ficus chosen for indoors usually performs very well with the heating on. They like bright light, even some gentle filtered sunlight, and don't tolerate sudden changes or drafts well. Ideally, find them a bright spot where they can stay more or less still, without being right next to the radiator or getting blown by hot air.
Although they are long-lasting and very decorative plants, it is advisable adapt irrigation to the cold seasonWater slightly less than in spring and summer, always ensuring that excess water drains out through the drainage holes and doesn't stagnate at the bottom of the pot. If the air is very dry, you can use gentle misting of the foliage or place a container of water nearby.
Sansevieria or mother-in-law's tongue
The Sansevieria, known as mother-in-law's tongue, is probably one of the most versatile plants which can be kept indoors. It tolerates drought, temperature changes, some lack of light, and even occasional watering issues. That's why it's perfect for apartments with central heating where you don't want to be constantly tending to the potted plants.
Its vertical and rigid leaves, with shades of green and yellow, They add a very decorative and modern touch. In living rooms, hallways, or bedrooms. It doesn't need misting or high humidity. All it appreciates is medium to bright light, without direct, scorching sun, and very moderate watering during the winter, allowing the soil to dry out completely between waterings.
Zamioculca (Zamioculcas zamiifolia)
In winter, the Zamioculcas appreciates stable, temperate temperaturesIt prefers temperatures around 18-22°C and suffers if placed directly above a radiator or next to a heat pump. However, it tolerates medium light very well and even slightly shady spots, although it will grow more slowly in those conditions. Again, watering should be infrequent during the colder months.
Aspidistra (pilistra or “donkey ears”)
The aspidistra is a classic houseplant that became famous precisely because It can withstand almost anything.Lack of light, dry air, temperature changes… It's no coincidence that it has been the typical houseplant for entryways and hallways for decades. Its long, arching, deep green leaves add an elegant and understated touch to any room.
In heated homes, the aspidistra behaves in a particularly resistant wayIt doesn't require much care or frequent watering. Simply prevent the soil from drying out completely for too long and place it in a bright location. As it doesn't like direct sunlight, it usually does well in slightly shady spots.
Peace lily or Moses' cradle
The peace lily is highly valued because It combines good indoor durability with a very decorative white bloom.It resembles a candle or a "cradle," hence its common name. It's a plant that thrives in the stable temperatures of homes, so moderate heating is usually not a problem for it.
However, the peace lily is somewhat more demanding when it comes to ambient humidity. In very dry environments, it greatly benefits from gentle sprays The leaves and proximity to sources of humidity such as fish tanks, water containers, or humidifiers can affect its health. If well cared for, it can continue to display bright green leaves and flowers even in the middle of winter.
Flowers that look great in winter, both indoors and outdoors
When we think of blooms, we usually imagine spring and summer, but There are plants that reach their peak bloom in the cold.Some can live temporarily or permanently indoors during the winter, as long as their light and temperature needs are met. Others prefer to remain outdoors, although they can be sheltered on the coldest days.
One of the common mistakes is worrying excessively when Plants slow their growth during this timeMany plants enter a kind of semi-hibernation: their growth slows down, their appearance changes slightly, and they stop producing new leaves as frequently. This is completely normal during the colder months, so there's no need to worry if you notice more "dormant" growth.
Cyclamen
Cyclamen is a bulbous plant that thrives in winterIt boasts unique flowers that appear upside down, in a beautiful array of pinks, whites, and reds. Interestingly, it doesn't tolerate intense heat well, so it's best to keep it in cool rooms or near windows where the heating isn't too strong.
Indoors with central heating, the cyclamen can work if It is kept away from radiators and in a very bright area.Ideally, it should be kept at slightly lower temperatures than the rest of the house. If it is subjected to an excessively warm environment, it will often lose its flowers prematurely and the bulb will go dormant prematurely.
Fuchsia or queen's earrings
Fuchsia, known as the queen's earrings, is a very decorative shrub because of its hanging flowerswhich look like small, brightly colored lamps. It is usually grown outdoors, but tolerates being moved indoors well when temperatures drop, provided the chosen location is bright and out of direct, intense sunlight.
It withstands a certain drop in temperatures and even It can bloom in autumn and early winterAs the cold weather intensifies, it goes into a dormant state and greatly reduces its activity. If you decide to keep it indoors, it's best to find a cool, bright spot for it, away from the hot air streams of heaters or heat pumps.
Amarilis
Amaryllis is another Very hardy bulbous plant with spectacular flowersLarge in size and with vibrant colors, its flowering cycle can perfectly coincide with winter, which is why it's very popular for decorating interiors during the holidays. It tolerates the environment of a heated house well, as long as there are no sudden temperature changes.
After flowering, the amaryllis It needs a rest period.During this period, watering is reduced and the above-ground parts are allowed to wither. It's important not to force it with fertilizers or transplanting in the middle of winter, but to respect its natural rhythm until the following season.
Chrysanthemum
The chrysanthemum is often associated with autumn, but Their flowers can remain vibrant for quite some time.even after being cut. When potted, it needs a large, well-nourished substrate to thrive, as well as plenty of light to maintain flowering.
Indoors with heating, it is advisable Place it where it receives bright light but not harmful sunlight.and ensure the substrate doesn't dry out completely during flowering. Once its peak bloom is over, it can be moved outdoors or left to rest, requiring less care until the following season.
Camellia
Camellia is a shrub of very showy and elegant winter flowersIt prefers shade or partial shade to intense direct sunlight. It is somewhat sensitive to soil type and humidity, but in return, it rewards gardeners with spectacular blooms when the rest of the garden seems lackluster.
It's not the easiest plant for permanent indoor heating, but It can be sheltered indoors during periods of extreme cold.Always in the brightest and coolest place possible. In general, it prefers to remain outdoors, well protected from the wind and with a suitable substrate.
Thoughts or violas
The pansy (viola) has a delicate appearance, but It is surprisingly resistant to coldIn fact, it thrives in cool outdoor environments and can bloom throughout much of the winter, provided the weather isn't extremely harsh. Its vibrant flowers brighten balconies, terraces, and planters while many other species are dormant.
Being an outdoor plant, It is only recommended to bring it into the house occasionally. If there are very severe frosts or episodes of intense cold, it can be placed in the sunniest area indoors, away from direct heating, and brought back outside when the cold snap has passed.
Basic care for plants in heated homes
Once the species have been chosen, the key part arrives: adapt care to winter conditionsAlthough many of these plants are hardy, it's best not to be too confident. With a few simple guidelines, you can make the difference between a vibrant green and wilted leaves mid-season.
Suitable and stable temperature
In general terms, Indoor plants thrive between 18 and 22°C During the day, and somewhat less at night. Continuously exceeding 22-23°C, in addition to driving up heating bills, further dries out the air and can accelerate plant stress, especially for those that prefer cooler temperatures.
Adjust the thermostat to Do not overheat the house It's beneficial both for your wallet and for the health of the plants and the people living in the house. Sleeping at slightly cooler temperatures, around 18-20°C, also helps you sleep better and prolongs the life of many species sensitive to excessive heat.
Control of environmental humidity
The biggest enemy of winter indoors is the extreme dryness of the airAn overly dry environment not only damages plant leaves, but also irritates mucous membranes and the respiratory tract in people. Therefore, it's advisable to monitor relative humidity and, if it's too low, take steps to increase it slightly.
One can resort to electric humidifiers or homemade solutions Place containers of water near radiators, group several plants together to create a slightly more humid microclimate, or put a fish tank in the same room. Misturing water near the leaves, without soaking them, also helps, especially with species like peace lilies or some palm trees.
Avoid direct heat sources
However tempting it may seem, it's never a good idea Place a plant directly above a radiator or in front of a stream of hot air. from an air conditioning unit. This concentrated heat burns leaves, dries out the substrate at record speeds, and can cause severe heat stress, with leaf drop and general weakening.
The recommendable thing is always maintain a safe distance between the pots and heat sources. If there's no other option due to lack of space, you can put up some kind of barrier (for example, a shelf) so that the hot air doesn't blow directly on the plant. The more uniform and gentle the microclimate, the better the indoor plants will thrive.
Adjusting irrigation during cold weather
In winter, the golden rule is that water takes much longer to evaporateIf you water them the same way as in summer, the result is usually a constantly damp substrate, suffocated roots, and, in the medium term, rot. Therefore, you almost always have to space out watering, especially with cacti, succulents, and slow-growing plants.
Ideally Check the soil before watering Insert a finger a few centimeters. If it's still damp, it's best to wait. Many species prefer a slight lack of water to an excess. It's also good practice to empty any standing water from the saucers under the pots so the roots don't remain constantly waterlogged.
Less fertilizer and no transplanting
During the winter, most plants They naturally slow their growth rate.Even those that tolerate heating well. Therefore, it makes no sense to force them with fertilizers or repotting during their dormant period. The wisest course of action is to reserve repotting and intensive fertilization for spring.
In these cold months, it's enough to keep them clean, control pests (which, although less frequent, can appear in warm indoor environments) and remove any dry or damaged leaves. This way, the plant conserves enough energy to sprout vigorously again when the longer, brighter days return.
Strategic placement and sufficient light
In winter, light becomes a scarce commodity, so The location of the plants is almost as important as watering.It's not about placing them in direct sunlight against the glass, but rather ensuring they receive the light they need. Each species has its preferences, but as a general rule, it's best to move them closer to the windows during the months with less sunlight.
If any outdoor plant does not tolerate the cold well, It can be moved indoors to the sunniest cornerHowever, it's important to avoid placing it in a corner exposed to hot drafts or sudden temperature changes. A small adjustment in its placement can make a big difference to its overall condition.
Periodic monitoring of the plant's condition
Although many of the species mentioned are hardy, it is always advisable check them from time to time with a quick glanceChecking the color and texture of the leaves, and detecting brown spots, dry tips, or widespread yellowing early on, helps to correct problems before they get out of control.
If the soil is always dry or always wet, if the leaves lose their shine or sunken areas appear, it's probably time to adjust the watering, move the plant to another location or slightly increase the ambient humidity. Small changes in time prevent regrets later.
By knowing which plants tolerate central heating best, understanding how temperature, humidity, and light affect them, and applying care adapted to winter, It is perfectly possible to enjoy a warm and green home all year round.From the everlasting ficus trees on porches to minimalist cacti, and including pothos, sansevierias, zamioculcas or peace lilies, there are options for all tastes and experience levels, so the cold and heating no longer have to be an excuse to give up on indoor plants.
