Choosing indoor plants for conservatories

The Best Indoor Plants for Conservatories

Back to list

So, you’ve got your brand new DIY conservatory, installed it yourself, and now it needs a bit of decorating.

There are many ways to decorate your conservatory – depending on what you want to use it for.

Most people choose to have it as an extra lounging area. Often this is a pleasant sitting space where you can relax. 

If this is the case for you, then surely it makes sense to brighten the place up with a few indoor plants? 

Adding some conservatory plants is yet another effective way in which you can ‘bring the outdoors in’. This means that your conservatory provides the perfect fusion between the fresh, green tranquility of your garden and the warm, soft comforts of your home’s interior. 

Beyond simple decoration, conservatory plants also work well as a standout design feature (depending on what type of vibe you’re trying to create). The best plants for conservatory design are explored in further detail in our all-encompassing conservatory interior design guide – so be sure to follow the link if you’re chasing some inspiration. 

On the other hand, if you’re not too sure where to begin – we’ve got a few suggestions right here to get you started…

How to choose the right conservatory plants for your home

There are a few things to consider when choosing the best plants for your conservatory:

1. What temperature is my conservatory?

If you buy a plant that needs tropical heat to survive (and thrive), you might find that your conservatory’s temperature is not an appropriate environment for it. To avoid disappointment, be realistic about what it is you need and check what temperature a plant needs to grow in first before you buy it. 

2. How high maintenance do I want my plants to be?

Think carefully about how much time you want to devote to the upkeep of your plants. People are sometimes tempted to get a climbing plant for a conservatory wall, for example. This is fine, but be aware that some can get a little out of control if left to their own devices – and could end up covering more space than you’d like.

3. Do I need to avoid poisonous varieties? 

Check if the plants you’re considering have any type of poisonous sap – it happens more than you’d think – which could fall into the wrong hands. And don’t forget to check whether any plants you’re considering are potentially poisonous to your pets, too. If in any doubt, choose safe, non-poisonous varieties.

Best plants for hot conservatories

Hot conservatories call for plants that can stand the heat. Here are some that can take it:

Cacti and succulents

These resilient specimens will be able to withstand your conservatory’s hotter temperatures come summer, but they won’t struggle if things get colder in winter. They’re also an excellent conservatory plant option if low maintenance is what you’re looking for.

Sago palms

A popular houseplant, sago palms are easy to look after. Known for their feathery foliage, these palms date back to prehistoric times, which accounts for their hardiness. Just make sure you don’t overwater them. 

Blue Hesper palms

Another great palm, the Blue Hesper likes to be in full sun with dry air – making it one of the best plants for a conservatory. This Central American-born species boasts large, fan-shaped leaves and doesn’t require any pruning. 


Bring some tropical colour into your conservatory with a mandevilla. These evergreen climbers flower in late summer. Water them moderately in spring, then mist daily in summer. 

Devil’s ivy

As conservatory plants go, this species is a low maintenance, yet attractive choice. They only need watering infrequently and can cool themselves and their surroundings when things get hot – pretty smart for a plant.


Best large conservatory plants

Size not an issue? Don’t be afraid to go big. Here are some grand conservatory plant ideas to get you started: 

Olive plants

It might surprise you, but olive plants can grow quite happily in conservatories. The olives themselves tend to arrive in summer, but they fall reasonably quickly, so keep an eye out for them. Bear in mind you will need to prune olive plants from time to time. 


This climbing plant is very flexible when it comes to temperature. They come in a range of beautiful vibrant colours, so make excellent decorative additions to your space. Depending on the specific type, they can grow up to six-foot-high. 

Rubber tree plant

These bold and beautiful specimens love a sunny spot, making them perfect conservatory plants. But they do prefer a little humidity, so give them a regular misting and watch them thrive. 


There are many different types of dracaena to choose from, including stunning red varieties. They’re a perfect fuss-free conservatory plant, because they like to be on the drier side and get plenty of light. 

Fishtail palm

These lush, bushy palms will make your conservatory feel instantly tropical. Their needs are simple – lots of light and lots of water. They can reach up to about five foot tall, so make sure you can give them the space they need to reach their full potential.
