Vertical gardening has been one of the biggest trends in horticulture in recent years and such gardens are growing in popularity all around the world.
If you're having trouble coming up with ideas for your garden, you could take inspiration from the world's tallest vertical garden in Sri Lanka.
Clearpoint Residences is a residential apartment block currently under construction ten kilometres outside the capital, Colombo. When it is finished, it will rise 46 floors above the ground and consist of 146 apartments.
Every apartment will come equipped with a garden terrace, creating a unique appearance in which the natural and the man-made seem to merge into one.
The intention behind the building is to enable occupants to experience 'ground floor living' despite being hundreds of feet off the ground.
Designed to make the building fully sustainable, the terraces will provide shade, absorb carbon dioxide and act as a barrier against sound.
They are to be watered with a special drip irrigation system, using harvested rainwater, recycled bathroom sink and shower water.
Shade provided by the plants will mean none of the apartments are exposed to direct sunlight, meaning air conditioning units can be reduced in size and consume less energy.
Solar panels installed on the roof will power common amenities such as public lighting, elevators, recycling systems and other utilities. Excess energy will be sold back to the national grid.
The building is due to be completed in 2016, so if you fancy buying a pad over there, you'll have to wait a little while yet. And don't worry – although many of the plants will come as part of the building, you'll also be able to grow your own.
You might quibble that the building isn't primarily a garden – it's a building first and foremost, with plants covering a large portion of the exterior.
But it's certainly a novel concept when it comes to building design and it has some very solid low-carbon credentials. When it comes to vertical gardening, it seems the sky really is the limit.
