Ideal Plants for Concrete Planters in the City

The buildings, roads, and parking lots in city centres leave little room for natural vegetation. Concrete planters are an easy and affordable way to introduce plants into a city. We have selected our top plants that are ideally suited to a city space. Uplift your outdoor city space with StreetScape concrete planters.




StreetScape manufactures landscaping elements for both suburban and city spaces. StreetScape is based in Cape Town and strives to uplift the Cape Town city centre through functional and beautiful landscaping elements.


A quick and fun way to add colour, life, and beauty to a city space is by adding plants. One way to incorporate more plants into a city space is with StreetScape concrete planters.




StreetScape Concrete Planters:


StreetScape produces concrete planters that are suitable for any city space. StreetScape concrete planters are high quality whilst still being affordable for a range of budgets. Improving your city space is easy with StreetScape concrete planters.


StreetScape concrete planters are perfect for outdoor spaces. The concrete ensures that each planter is strong, durable, and robust against any weather conditions. You will not have to worry about your concrete planters becoming chipped or damaged.


There are six different StreetScape concrete planters to choose from. The concrete planters vary in size, shape, design, and concrete finish. StreetScape offers this variety so that you can find concrete planters which are ideally suited to your space and the plants you wish to add to your outdoor city area.


Benefits of Plants in City Spaces:


Cities can often be concrete jungles with minimal natural vegetation. Adding a few StreetScape concrete planters with selectively chosen plants can have multiple benefits for you, your company, and the city.


Beauty: Pops of plants will add some much-needed natural vegetation to a city space. The addition of concrete planters outside your business in the city centre will improve the beauty of your outdoor area, your business façade, and your stretch of city space.


Privacy: If your company is located on a ground floor unit there can be minimal privacy as cars and people stream past your windows. Concrete planters placed in front of your windows with medium-height plants can increase the privacy of your company.


Heat Islands: Many South African cities are affected by urban heat islands. Urban heat islands are city areas that experience warmer temperatures when compared to surrounding suburban or rural areas. This is often caused by the multiple buildings, roads, parking lots, and lack of natural vegetation in a city. The addition of concrete planters brimming with a variety of plants or trees can help towards temperature reduction in a city.


Combat Pollution: The high volume of businesses and vehicles in a city centre results in an increase in air pollution. Plants are well-known to help with reducing air pollution thus the addition of plants will work towards improving the air quality in the city.


Ideal Plants for Concrete Planters in a City:


We have selected a variety of indigenous plants which will work for any city space. Whether you are sprucing up the area outside your business or improving the city space, any of these plants are ideal for StreetScape concrete planters.


1) Short-leaved Aloe:


The short-leaved aloe, or aloe brevifolia, is a South African plant that is indigenous to the Western Cape. The short-leaved aloe is blue-green in colouring and each leaf is edged with sharp white spikes. Short-leaved aloes typically grow to 40cm in diameter and 30cm in height.




Short-leaved aloes are an affordable plant to use in a concrete planter. Short-leaved aloes have offsets that grow at the base of the plant. These can be easily pulled off and placed into the soil where they will root and grow. You will only need to purchase a few short-leaved aloes and soon your concrete planter will be over-flowing.


If you have chosen to use short-leaved aloes in your StreetScape concrete planter, ensure that they receive morning sunlight only. The short-leaved aloes will turn red and possibly die if exposed to excessive sunlight.


Short-leaved aloes are a succulent. They need minimal water and can survive through drought seasons. The short-leaved aloe is ideal for sidewalks or outside businesses as they need little maintenance and are a beautiful pop of greenery to an outdoor city space.




Short-leaved aloes have a shallow root system which means they would work ideally in the StreetScape Square 600 or Round 600 concrete planter.


2) Mother In Laws Tongue:


The sansevieria trifasciata, which is commonly known as mother in laws tongue or snake plant, is an ideal plant for concrete planters in city spaces. This South African plant is trending and can be found in homes and cities across the world.


The sansevieria trifasciata gains its colloquial name from the long vertical leaves which have a sharp point. Mother in laws tongues have dark green hardy leaves with lighter green lines and certain species can have a yellow trim.


Mother in laws tongues are exceptionally easy plants to grow. They thrive in warmer temperatures, are not fussy with the amount of sunlight they receive, and only need minimal water. Minimal maintenance plants are ideal for city spaces.


Mother in laws tongues can also be easily propagated which means you can easily double your quantity without spending more money on plants for your outdoor city space.


3) Spekboom:


Spekboom, or portulacaria afra, is an indigenous succulent that is useful for city centres. Spekbooms make any urban space beautiful with their dense, bright green leaves and red-brown trunks. Spekbooms can grow to an astonishing 5 metres tall, which can be easily used to create privacy in front of businesses.


Spekbooms are the best plant for city spaces as they have been shown to be one of the best carbon neutralising plants in the world. City spaces are often highly polluted with carbon dioxide. Planting spekboom in concrete planters around the city can radically reduce the carbon dioxide in the city atmosphere.


Spekboom will prosper in concrete planters in city spaces. Spekboom can thrive in direct or indirect sunlight, need minimal water, and enjoy warm, humid environments. Although Spekbooms are typically found in the Eastern Cape, they adapt to their surroundings and will flourish in most city centres across South Africa.


Easy to grow and great for carbon dioxide reduction; it is easy to understand why the spekboom is becoming known as the miracle plant. We suggest the StreetScape 1200 Stacking concrete planter for spekboom in city spaces.




4) Agapanthus:


Agapanthuses are an indigenous plant that has become a landscaping staple for city spaces. Agapanthuses have strappy, fleshy green leaves which will add a pop of green all year round to an outdoor city space.


Agapanthus can grow to 2 meters tall, but there is also a dwarf variety that will grow to 20cm. The variation in size makes it a suitable plant for any of the StreetScape concrete planters on a sidewalk or outside a business in the city.


Agapanthuses have beautiful funnel-shaped flowers which grow on a long stem and burst into a cluster of either white or blue-purple flowers. Agapanthuses are an easy plant to inject some colour and vibrancy to a city space overwhelmed by buildings and roads.


Agapanthuses are suited to city spaces as they are easy to grow and maintain. Agapanthuses require full sunlight, minimal water, and well-drained soil to thrive.


Agapanthuses are ideal plants for a concrete planter as they do not mind being planted closely together in a small space. As they grow and expand in size, you can easily divide the agapanthuses and plant into a new concrete planter.




5) Clivia:


Clivia minniata, which is colloquially referred to as clivia or bush lily, is a South African plant that is loved both locally and globally. Clivias have dark green strappy leaves which have a glossy appearance and grow in arches.


In Spring, clivias produce vibrant trumpet-shaped flowers. The clivia flowers are typically a striking orange but can also be a gentle yellow. There are multiple hybrid clivias that have resulted in an increased variety of colouring. These are typically specialised and are higher in cost.


Clivias will only grow in shady areas as their leaves tend to burn in direct sunlight. Clivias are ideal for covered business fronts or shaded parking lots in city spaces. Clivias also require regular watering and need excellent drainage when planted in a concrete planter. The beauty clivias add to a city space outweighs the maintenance they require.


Clivias need to be planted with a space of 10cm between them which makes the larger StreetScape Round 900 concrete planter ideal for planting clivias in your city space.




6) Society Garlic:


Tulbaghia violacea, or commonly referred to as society garlic, is a beautiful indigenous flowering plant. Society garlic grows in a clump with long, slender grey-green leaves. Society garlic grows 60cm tall and 25cm in diameter.


Society garlic has large umbels which vary from lilac to lavender to pink. These beautiful pops of colourful flowers will add a delicate beauty to any city space during Summer and Autumn.


Society garlic gets its colloquial name from the subtle garlic scent the leaves and flowers emit. Society garlic is also edible and will add an onion-garlic flavour to your dishes.


Society garlic will flourish in a concrete planter in a city space. Society garlic can be planted in partial or full sun. Society garlic needs regular watering whilst they are growing but less water whilst they are flowering. Ensure that there is adequate drainage in your concrete planter when planting society garlic.


Society garlic is ideally suited to a smaller concrete planter, such as the StreetScape Round 400. Invest in a few concrete planters for multiple bursts of purple and green vegetation around the city space.




7) Paddle Plant:


The paddle plant (kalanchoe thyrsiflora), also known as the flapjack succulent, is a unique indigenous plant. The paddle plant gets its colloquial name from the large, flat, scallop-shaped leaves. The leaves are a subtle jade-green with hints of yellow and a rust-red trim.




Paddle plants have a tubular flower that grows at the end of a long stem that can reach 1 meter tall. The flowers are generally yellow in colouring which creates a contrast between the green and red in the leaves. The flowers also have a strong, sweet smell which will elevate the city space they are planted in.


Paddle plants are suitable for a concrete planter in a city space as they require minimal maintenance. The paddle plant grows in direct sunlight in warmer environments which is easy to find in a city. Paddle plants only require water when their soil is dry.




It is easy to improve city spaces with the addition of StreetScape concrete planters brimming with suitable plants.
