Winter in the UK can feel like the end of the gardening year. Outdoor beds are resting, pots are wrapped up, and daylight hours seem to disappear overnight. But colder months don’t have to mean giving up on greenery altogether. In fact, winter is the perfect time to bring plants indoors—especially hardy houseplants that don’t mind cooler temperatures and occasional drafts from windows.
Cold windowsills can be a challenging spot for many indoor plants. Temperatures drop quickly at night, sunlight is weaker, and dry indoor air can add extra stress. Choosing the right plants makes all the difference. The good news is that plenty of houseplants not only tolerate these conditions but actually thrive in them.
Below is a carefully chosen list of plants that cope well with cold windowsills during a UK winter. These options are low maintenance, resilient, and ideal for keeping your indoor space green and lively when the weather outside is less than inviting.
1. ZZ Plant (Zamioculcas zamiifolia)
The ZZ Plant is one of the toughest houseplants you can own. Its thick stems and glossy leaves store water, allowing it to cope with temperature fluctuations and infrequent watering. This makes it an excellent choice for cold windowsills where soil can take longer to dry.
It prefers bright, indirect light but adapts well to lower light levels common in winter. Water only when the compost is completely dry, as overwatering is its biggest enemy. With minimal effort, the ZZ Plant adds a polished, modern look to any room.
2. Snake Plant (Sansevieria)
Few plants handle neglect and cold air as well as the Snake Plant. Its upright, sword-like leaves are extremely hardy and can tolerate cool temperatures, dry air, and low light. This makes it ideal for windowsills that may feel drafty during winter nights.
Snake Plants prefer dry soil, so watering every few weeks is usually enough. They also help improve indoor air quality, making them a practical and attractive winter companion.
3. Aloe Vera
Aloe Vera is well suited to sunny windowsills, even during colder months. While it prefers light, it doesn’t mind cooler temperatures as long as it’s kept dry. Aloe stores moisture in its fleshy leaves, allowing it to cope well with reduced watering in winter.
Be cautious not to let the leaves touch icy glass, and always check that the soil is dry before watering. With its sculptural form and practical uses, Aloe Vera is both decorative and functional.
4. Jade Plant (Crassula ovata)
The Jade Plant is another succulent that thrives on neglect, making it perfect for winter conditions. It tolerates cooler rooms, dry air, and missed waterings with ease. Its thick, oval leaves retain moisture, allowing it to survive long gaps between watering.
Jade Plants enjoy bright light and can handle cooler windowsills as long as they’re protected from frost. They add a calm, structured look to indoor spaces and are known for their impressive longevity.
5. Chinese Evergreen (Aglaonema)
If your windowsill doesn’t get much sunlight in winter, the Chinese Evergreen is an excellent choice. This plant adapts well to low light and cooler temperatures, making it ideal for UK homes during the darker months.
Its patterned leaves add visual interest without demanding constant attention. Keep the soil lightly moist, but never soggy, and avoid cold drafts directly hitting the leaves. With basic care, this plant remains attractive year-round.
6. Christmas Cactus (Schlumbergera)
The Christmas Cactus is perfectly suited to winter living. Unlike desert cacti, it prefers cooler temperatures and indirect light, which encourages flowering. Placed on a bright windowsill, it can produce vibrant blooms in late winter.
Water lightly and allow the compost to dry slightly between waterings. This plant rewards minimal care with colourful flowers that bring life and cheer to gloomy winter days.
7. Ponytail Palm (Beaucarnea recurvata)
Despite its name, the Ponytail Palm isn’t a true palm, but it is exceptionally resilient. Its swollen base stores water, helping it cope with dry air and infrequent watering during winter.
It tolerates cooler indoor temperatures and adapts well to bright windowsills. Slow-growing and visually striking, it’s an excellent long-term houseplant for low-effort winter care.
8. Clivia
Clivia is well known for thriving in cooler indoor conditions. It prefers indirect light and actually benefits from lower winter temperatures, which help trigger flowering. This makes it an ideal candidate for cold windowsills.
Water sparingly during winter, allowing the compost to dry slightly. When in bloom, Clivia produces bold, colourful flowers that brighten any indoor space with minimal effort.
9. Fiddle-Leaf Fig (Ficus lyrata)
While often seen as fussy, the Fiddle-Leaf Fig can adapt well to winter conditions when placed correctly. It prefers bright, indirect light and consistent placement away from sudden temperature changes.
A cool but not freezing windowsill can work well, provided the leaves don’t touch cold glass. Water only when the top layer of soil feels dry. With patience, this plant becomes a striking focal point in any room.
10. Philodendron
Philodendrons are reliable, adaptable houseplants that handle winter conditions better than many others. They tolerate cooler temperatures, low light, and irregular watering, making them well suited to UK winters.
Their broad leaves add softness and texture to indoor spaces. Keep them away from direct cold drafts and water sparingly during the colder months for best results.
Keeping Plants Happy on Cold Windowsills
Even hardy plants benefit from small adjustments in winter. Use insulating mats or trays under pots, move plants slightly away from glass at night, and reduce watering overall. Avoid feeding until spring, as growth naturally slows during colder months.
Winter doesn’t have to mean a dull, plant-free home. With the right choices, cold windowsills can become the perfect spot for resilient indoor greenery. These plants prove that even in the darkest, chilliest months, your love of gardening can continue indoors—bringing calm, colour, and life into your home all winter long.
