Spekboom Benefits & How to Grow It (South Africa)

If you have spent any time in a South African garden centre or scrolled through local gardening social media, you have likely heard of spekboom. This humble, hardy succulent is having a moment — and for good reason. Known scientifically as Portulacaria afra, it answers the common search query “spekboom in english” with two charming names: the porkbush or elephant bush. It is indigenous to South Africa, thriving mostly in the Eastern Cape’s succulent thickets, where it forms dense, verdant carpets across the landscape.

Why Spekboom Is Famous

The buzz around spekboom centres on its remarkable ability to absorb carbon. The South African National Biodiversity Institute (SANBI) describes this plant as an excellent carbon “sponge,” drawing carbon from the atmosphere and storing it in its fleshy leaves and stems. That sounds like a climate hero, and in many ways it is.

However, before you plant a forest of spekboom expecting to offset your entire carbon footprint, consider the balanced view from the Botanical Society of South Africa. Their analysis suggests that popular hype has somewhat overstated spekboom’s powers. It is not a silver bullet for climate change — its benefits depend heavily on restoring it in the right habitat, namely the degraded thickets of the Eastern Cape where it naturally belongs. Planted randomly in gardens or in the wrong biome, its carbon-capturing potential is far less dramatic. So, enjoy it for what it is: a tough, beautiful, useful plant — not a miracle cure.

Practical Benefits for Your Garden

Setting aside the climate debate, spekboom offers a host of practical, everyday benefits that make it a garden favourite:

• Waterwise wonder: As a succulent, spekboom stores water in its leaves, making it exceptionally drought-tolerant once established. It is perfect for water-scarce regions.
• Fire-resistant green firebreak: In the right setting, its fleshy, moisture-rich foliage can act as a natural firebreak, slowing the spread of veld fires.
• Edible leaves: The leaves have a pleasant, sour tang. They can be added to salads, or used to make a refreshing chutney — a fun, homegrown culinary experiment.
• Bonsai and hedging star: Spekboom responds beautifully to pruning. You can train it into a striking bonsai specimen or clip it into a dense, neat hedge.
• Wildlife magnet: It is a superb pollinator plant, attracting bees and other insects with its small, star-like flowers. It is also a favourite food source for elephants and other browsers in the wild.

How to Grow Spekboom

Growing spekboom is wonderfully simple, which adds to its charm. Here is what you need to know:

• Sunlight: It thrives in full sun but will also tolerate light shade. For the best growth and that characteristic lush green colour, give it as much sun as you can.
• Soil: Well-drained soil is non-negotiable. While it can survive in poor soils, it will sulk in waterlogged conditions. If your garden soil is heavy clay, consider planting it in a raised bed or a large pot with gritty, succulent mix.
• Watering: Once established, it is incredibly drought tolerant. Water sparingly — during the growing season, allow the soil to dry out completely between waterings. In winter, reduce watering significantly.
• Frost sensitivity: This is a crucial one for inland gardeners. Spekboom is frost-sensitive and will suffer damage in cold winters. If you live in a frost-prone area like Gauteng, plant it in a protected spot against a warm north-facing wall, or keep it in a pot that you can move indoors or under cover during cold snaps.
• Propagation: The easiest method is by stem cuttings. Simply cut a healthy stem, let the cut end dry out for a day or two, and then stick it directly into the ground or a pot. Water it sparingly until roots form. It really is that simple.
