Spekboom is good for: oxygen and health benefits

South Africa’s miracle plant

The Spekboom is a nice-looking, indigenous to South Africa, drought-hardy plant. Spekboom is good for:

Spekboom is good for growing a windbreak or privacy hedge. These plants are very easy to shape when a box hedge is desired.

  • Spekboom is known for its incredible carbon-storing capabilities and
  • many health benefits.
  • It is one of but a few plants that release oxygen during day and night and as Spekboom creates clean air – it is a fantastic indoor plant
  • It promotes soil binding flora, which helps prevent erosion.
  • Another benefit of the Spekboom is being edible. The plant offers many health reasons and it is an eady-to-grow food source.
    This sprawling shrub, or small tree, naturally grows in the rocky areas of the bushveld and semi-desert regions. Bees and butterflies love its masses of soft pink nectar-rich flowers, which is followed with small papery three-winged fruits.

Indigenous people use the plant for medicinal and domestic purposes, including:

  • Spekboom has skin soothing properties and treats ailments like rashes, insect stings, sunburn or blisters with crushed leaf juice.
  • Plant parts treat heatstroke and thirst by sucking a leaf or throat and mouth infections by chewing leaves.
  • The stems are good building material when dried and used as thatch for roofing of the huts/homes.
  • Mozambican breastfeeding mothers believe these leaves help increasing their milk production by eating the leaves.
  • The leaves are best eaten in the mornings while still sweet. The succulent leaves turn more sour and bitter with the climbing sun.

Most importantly: Comparing the Amazon forest hectare for hectare with a Spekboom thicket and Spekboom wins at removing carbon dioxide from the atmosphere. Ten times over. 5 Hectares of Spekboom can remove 20 – 50 tonnes of carbon per year.

2020 kicked off for South Africans with this Spekboom Challenge:
A) plant 10 spekboom trees,
B) share and post it on Social Media as #spekboomchallenge and
C) challenge a friend to do the same. (Gardening Eden wants to up this challenge to 20 spekboom trees in 2020 – add #20spekboomchallenge to your share)
Because of this challenge, thousands of spekboom trees have since been planted and in some cases, the challenge amount has grown to 10 plants per person (or more). Which is great since a single mature spekboom can remove 8.5kg of carbon a year. Keep in mind that typically 9.18 tons of carbon emissions per person are released from vehicles alone.

More good news…
Stellenbosch – outside Cape Town, South Africa – will soon host the largest African labyrinth with 13 circuits – consisting of spekboom trees. The garden diameter will be 220m and visible far from above.
It will be called “The Great Labyrinth of Africa” and be built at the Stellenbosch Bridge Smart City development.
“If we don’t regress carbon emissions by 2025, we’ll go past the tipping point and all of humanity will face extinction,” said Peter Shrimpton, Chief executive of the Heart Capital and founder of the Great Labyrinth Project .

The Labyrinth of the Chartres Cathedral in France is the design that the “The Great Labyrinth of Africa” is based on.

Propagating is easily done from cuttings in spring, summer and autumn. Keep them dry-moist and use river sand to root in – and ensure your final soil is well-draining. These plants are quite fast-growing and will not need, but respond, to compost and water. Seeing that this succulent needs very little to thrive – growing as many as possible is ideal. It is ideal for windy areas as a windbreak. They can be planted in dry desert or coastal gardens.

Spekboom is the best plant for the beginner gardener because it needs very little attention. As long as you elliminate poor drainage and overwatering, you can’t really get it wrong. Since this anazing plant is a greenhouse hero, it shouldbe on every balcony and windowsill, and we believe all traffic islands and highways should be hedge-planted with it too.

Celosia a.k.a garden cockscomb

Sensational Celosia a.k.a garden cockscomb

Celosia

Celosia a.k.a garden cockscomb, a member of the Amaranthaceae family, is also known as garden cockscomb, or wool flower, and originated in tropical Asia, most commonly India. It is invaluable as a mass-planted bedding variety, container filler, and glorious mixed summer-border specimen. The flowers show in vibrant shades of orange, yellow, bronze, red, scarlet, pink and magenta, so make for wonderful ‘hot-spots’ of intense, textured colour in the garden.

There are two distinct species of Celosia. C. argentea is cultivated for its tall, showy heads of dainty, plumed flowers. C. cristata is a lower growing plant, and produces distinctive heads of stiff, compact, densely packed blooms. They put on a long and delightful display of colourful abundance during the warmer months. Hybridization has resulted in the availability of tall and dwarf varieties in both species.

Celosia, a.k.a garden cockscomb, was originally classified as a weed, but has become an incredibly popular summer bedding variety. It can take lots of direct sunlight, and requires only minimal care and watering once established. The plant is hardy and wind-resistant, so is particularly useful in gardens which are exposed to strong winds, or are located in coastal areas.

Celosia can be grown with success in all regions of the country. It will do particularly well in well-drained soil enriched with compost, and with an occasional sprinkling of complete, water-soluble fertilizer. Varieties such as celosia argentea ‘Pyramidalis’, with its brilliant red clusters of feathery flowers, is just one example of the many cultivars which bring vibrant colour, and enduring vigour to the summer landscape.

Truly a biennial, but treated as an annual this species produces fragrant yellow flowers, which open towards evening, thus the name. These summer flowersare hibiscus-like and its foliage is prominently mid-ribbed.
O. macrocarpa (30cm) is a smaller variety with yellow summer flowers.

This 1 – 2m tall plant lives 2 years, but self-sows and is perfect for dry, open soils in full sun. As Evening Primrose Plant Uses range from edible to medicinal – this plant is a must have, especially in coastal drought-stricken gardens. It does not need a lot of water and needs to be left alone.

Evening Primrose seeds can be sown in sown in autumn or very early spring.

The yellow spring- and summer flowers only appear at night or on overcast days and each flower lasts a single night. These flowers can be smelled from afar as they also have a strong lemon scent. The small seed pods appear at the end of summer and contain many red seeds.

Evening Primrose Plant Uses: food

All of the Evening Primrose is edible.
– The highly nutritius (pre-flowering, early spring) Evening primrose leaves contain tannins, flavonoids, mucilage and sugar, resin and phytosterols. Add them to your diet and menu as you would baby spinach.
– Evening Primrose seeds are high in proteïn, oil and essential amino acids.
– The (young) stems are peeled first and then eaten raw, steamed or fried.
– The fruit, or seed pods make a good flash-fried snack with dip.
– The edible spring and summer flowers are sweet and can be added to deserts, salads or as garnish.
– Treat and eat the roots like any root vegetale. Roots from pre-flowering young plants are best.

Evening Primrose Plant Uses: Medicinal

The flowers and seeds are harvested during summer to be dried for teas or to extract the oils. The entire plant can be dried in autum, after flowering, for herbal use later.

Evening Primrose seeds are known for their amazing oil – which has been used to treat eczema, the Sjögren-syndrome, premenstrual syndrome (PMS) and menopausal symptoms, polyarthritis and multiple sclerosis.

The Native Americans traditionally boiled the entire plant as a tonic tea for energy. They also recommended the roots as an external treatment for piles and boils.

Medicinally, Evening primrose can be consumed as dried – in the case of leaves and flowers – as well as oils – and capsules is the most common form.

Experts advice should always be seeked before self-medicating and recommend dosage amounts should strictly be kept to.

Caution should especially (but not solely) be taken by:
– pregnant and breastfeeding mothers;
– people prone to epilepsy, seizure disorders, schizophrenia or mania;
– patients with bleeding disorders or taking medicine that may increase bleeding as Evening Primrose can increase the risk further.

Evening Primrose Plant Uses: Permaculture
– The night flowers attract night time pollinators
– Considered to be allelopathic to weeds by interfering with  the germination and growth of weeds.

– Because of the above reason, this is an excellent addition for a garden as cover-crop.  Match it with a legume as it needs a bit of nitrogen.
