Portulacaria afra, better known as Spekboom

Portulacaria afra, better known as Spekboom, is an indigenous evergreen succulent tree that is predominantly found in the Eastern Cape. The tree forms an important part of the Valley Thicket Biome as it is both fire-resistant and water-wise.


Climate & Photosynthesis
Spekboom is able to adapt its process of photosynthesis depending on its conditions and availability of water. In wet conditions it uses the same system as rainforest plants and switches its system to one used by desert cacti in dry conditions. Through this switch, it is able to store solar energy to photosynthesise at night when temperatures are cooler.

Studies have shown that a single hectare of Spekboom is able to convert 4.2 tons of carbon-dioxide into oxygen per year. The tree’s carbon-storing capabilities makes it up to 10 times more effective than any tropical rain forest.


Structure & Growth
Spekboom flourishes in warm summers and areas where rainfall is between 250 and 375mm per year. During Spring, star-shaped pink or light purple flowers appear which can be used to make honey. The tree’s cork-like roots measure up to 20cm in diameter and can reach heights of between 2.5 and 4.5m, making it ideal to use as a natural hedge.

Health Benefits
Spekboom is rich in manganese, cobalt and magnesium. It also contains micro elements, iodine and selenium which act as an antioxidant. The leaves have a refreshing, slightly tart, lemony taste and can be used to treat a number of ailments including heart burn, dehydration, exhaustion and heat stroke. The leaves are typically suckled on or can be eaten as part of a salad.IMG_20180618_162107.jpg

In order to propagate Spekboom, cut a small branch just below a node. Remove the bottom leaves and dip the end of the stem into hormone powder. Create a small hole in soil and plant the stem. New roots will form on the stems within 3-4 weeks. Plant the stems in the desired locations and fill the holes with soil. Water the stems well to ensure that the roots settle. Spekboom grows best over a period of three years or greater and can reach ages of up to a 100 years.FLORAL FRIDAY FOTOS

Leucospermum ‘Calypso Red’

This indigenous plant produce beautiful clusters of creamy yellow flowers that turn dark crimson red as they mature. As they only grow about 1m x 1m, they are perfect for small gardens and containers. It’s also a low maintenance plant and ideal for low water use gardens. Also suitable to plant in coastal gardens.IMG_7141

Plant your Calypso Red in well drained acidic soil (use Arnelia Premium Potting and Planting Mix). Although drought tolerant (once established), you need to water your plant regularly and well for the first 2 years. Plants in containers need to be watered daily.IMG_7143

Leucospermums are sun loving plants – so plant your Calypso Red in a sunny spot in the garden. Never fertilize – as this will burn your plant’s roots. Cut back dead flower stems to maintain a compact shape. Lastly, always remember that these plants do not like root disturbance.IMG_7144FLORAL FRIDAY FOTOS
