Introducing a touch of greenery to a conservatory may be all you need to brighten your space and add character.
A conservatory is far more than just an extension of your home – it offers a bright, relaxing space that helps connect your indoor and outdoor living areas.
And one of the most effective ways to make your conservatory feel more vibrant and welcoming, or calming and serene, is by introducing the right plants.
Thanks to large windows and glazed roofs that flood the room with natural light, conservatories create an ideal sheltered environment for many varieties of indoor and tropical plants to flourish.
Whether you want to create a lush and exotic retreat, curate a colourful flowering display, or introduce low-key, low-maintenance greenery, the right conservatory plants can completely transform your space into a garden oasis.
If you’re unsure where to start, explore our list of some of the best conservatory plants below.
Why are conservatories so good for plants?
Conservatories provide unique growing conditions that many plants love.
With plenty of sunlight, controlled temperatures and protection from wind and frost, they can support a wider range of plants than many other areas of the home.
South-facing conservatories are especially suited to sun-loving varieties, while cooler north-facing rooms can support more delicate greenery which prefers indirect light.
Plants also help enhance the conservatory environment itself – they can improve air quality, soften the appearance of glazed spaces and create a calming atmosphere that feels connected to nature.
Whether you use your conservatory as a dining area, reading room or entertaining space, adding plants is one of the simplest ways to make it feel more inviting and relaxing.

Tips for looking after your conservatory plants
Watering and humidity:
Different plants have different watering needs. It is worth noting that conservatories can dry out quickly in summer due to increased sunlight and heat.
To maintain healthy plants, you should:
- Water according to the season
- Avoid waterlogging
- Mist tropical varieties regularly
- Group humidity-loving plants together
Seasonal care advice:
Although they protect from external elements such as wind, rain and frost, internal conservatory temperatures can still fluctuate throughout the year.
During summer, south-facing conservatories have the potential to become extremely warm, while winter temperatures may drop considerably if you choose to leave the space unheated.
In summer:
- Increase watering frequency;
- Provide ventilation where possible;
- Move delicate plants away from intense direct sunlight
In winter:
- Reduce watering;
- Protect tropical plants from cold glass;
- Monitor humidity levels carefully
What plants can I grow in an unheated conservatory?
If you decide not to heat your conservatory, choose plants that can tolerate cooler winter temperatures.
Hardy succulents, palms and Mediterranean plants are excellent choices because they can handle temperature fluctuations more effectively than delicate tropical species.
Things to look out for when choosing conservatory plants
When selecting plants to enhance your conservatory design, consider:
1) Conservatory temperature
Some plants thrive in sun-filled conservatories, while others prefer cooler environments.
Also, some plants need shade rather than long periods of direct sunlight.
2) Maintenance levels
Climbing plants and tropical varieties may require more care than succulents or palms.
Some varieties need more regular watering, feeding and moving around depending on the season or type.
3) Pet and child safety
Some houseplants can be toxic if ingested, so always check before buying.
