Perennials are increasingly being used in vertical plantings. We’re seeing more and more of these living walls full of perennials appearing in our streetscapes. Keeping a number of their requirements in mind, many kinds of perennials are suitable for this purpose. Densely developed parts of the city are particularly good locations, since these plantings can contribute to a healthy living environment there. From providing natural air-conditioning to reducing noise.
- The release of water vapour from their leaves has a cooling effect.
- Since these living walls warm up more slowly during the day, they release less heat at night.
- Their leaves improve air quality by absorbing CO2 and pollutants in the air such as soot, particulate matter and nitrogen oxides.
- Walls covered in plants absorb 2.5 to 3 decibels of sound, so they reduce street noise.
- And they also enhance biodiversity.
The structure of a vertical planting using perennials consists of facade panels for holding growing medium and also an irrigation system for watering and fertilising. New systems making use of new materials and techniques are frequently becoming available. The wall is densely planted so that little if any of the supporting structure is visible. This provides a beautiful finished look as soon as the installation is complete.
Sun and shade
Many kinds of perennials can be used to cover living walls. The choice depends on their growth habit and the number of hours of sun they will receive. Good choices for a sunny wall would include Bugleweed (Ajuga reptans), Cranesbill (Geranium), Lamb’s Ear (Stachys byzantina) and Fountain Grass (Pennisetum ‘Hameln’). Deer Fern (Blechnum spicant), Elephant-eared Saxifrage (Bergenia), Lungwort (Pulmonaria) and Coral Bells (Heuchera) are just a few of the perennials useful for a shady wall.
The facts Installing living walls requires professional expertise. Since they have to be checked weekly, green walls supported by facade panels are not exactly low-maintenance. Nevertheless, their advantages for public green spaces more than outweigh their costs.

SubZero is a landmark building on the Floriade terrain where businesses, students and research institutions develop crossover innovations around the themes of nutrition, health and wellbeing.
Flevoland is the largest polder in the Netherlands where people live and work on an average of five meters below sea level. The pavilion portrays this in a unique way. A five-meter thick layer of this fertile ground is lifted up to the sea level, hence the name SubZero.
The space underneath this earth layer is enclosed by a reflective façade creating the illusion that the mass floats effortlessly above the ground. Once per day at high tide, a cloud of water vapor up to the sea level line is generated to water the plants on the plot and elevated rooftop. In so doing, a link is made to the sea and related themes like climate change, the subsiding earth and increasing salt content of the polder.
During the Floriade in 2022, the Innovation Workshop will function as the Flevoland Pavilion. Here visitors can see and experience the innovations that have been developed in the period leading up to the Floriade.

The final bill for organising the Floriade – the garden show which takes place in a different part of the Netherlands every 10 years – is likely to be almost triple the original budget, the Financieele Dagblad said on Wednesday.
The next Floriade will take place in Almere in 2022, but the cost is now set to hit €28m, compared with the original budget of €10m. It could be as high as €35m, according to one council committee. Almere’s town council is due to discuss the mounting costs of staging the event on Thursday evening, but has already decided to accept the new financial setback, the paper said.
The higher bill is partly due to Almere’s plan to expand the concept into a ‘world garden show’, combined with the development of a new ‘green’ city district with 660 homes. The cost of making the land ready for building, bills from external advisors and extra input from the city’s civil service are behind the higher bill, the FD said.
The Floriade in Venlo, Limburg in 2012 was also a financial flop and failed to boost tourist numbers. Local entrepreneurs had expected a surge in visitors but the number of tourists to the region only reached 2.5 million, 100,000 down on the previous year. Local councils were left with a €9m bill for running the show.
