Aloe thraskii (Dune Aloe)

Aloe thraskii (Dune Aloe)  

During one of our walks on the beach at Umdloti, not far from Ballito (KwaZulu Natal), I came across these large Aloes growing right on the beach. Fascinating! Not many plants can withstand the onslaught of wind and sea spray and yet, here was this beautiful specimen absolutely thriving in these conditions. Hence the name, Dune Aloe.

Indigenous to South Africa, it is a lovely plant for coastal gardens. This Aloe is a single-stemmed plant with giant, thorny-edged leaves that curve outwards and downwards, like fleshy arches. The sturdy inflorescence's with their racemes of bright yellow flowers appear in June and July and it is one of the few aloes that will withstand wet conditions

The Dune aloe grows fast in cultivation and is especially suited for coastal situations as it tolerates wind and salt air. It can be grown in inland gardens with mild winters and not overly damp summers. 

It can grow up to 10 feet (3m) tall and is naturally found in dune vegetation along the coast of KwaZulu-Natal and the Eastern Cape of South Africa. It is a hardy plant but not completely frost resistant.

Aloe thraskii is classed as Near Threatened in its natural habitat, due to habitat loss from urban and coastal development and illegal collecting for the specialist succulent horticultural trade. Experts estimate that 20-30% of the habitat has been lost to urban and coastal development in the last three generations (generation length 20 years). Severe storms are also likely to become more frequent with climate change, and may impact more severely on dune systems in the future.

Crassula multicava

For months I've been passing this Crassula on my walks and then, suddenly this week, a pink mist of blooms greeted me as I rounded a bend. I knew all along that it was a Crassula, but the flowers finally allowed me to do a full identification.

Crassula multicava is particularly useful for dry shade and to cover unsightly spots. It is tender to frost. There is a distinct difference in appearance depending on the position in which the fairy crassula is planted: in deep shade the leaves are larger and dark green and the plant has fewer flowers while in full sun the leaves are smaller and light green and flowering is profuse.

The flowers are tiny stars on thin stems held above the leaves

And just look at all the benefits of this gorgeous ground-cover!

Indigenous to South Africa, it is found from the southern part of the Western Cape, through the Eastern Cape to Natal and Mpumalanga, in thickets, along river and stream banks and in forest margins. Spreads easily, but it  responds well to pruning: use hedge cutters to remove as much of the foliage as you wish - recovery time is short and the reward is a dense carpet from which a pink mist of blooms will arise. Prune after flowering and seeding have taken place and again in early to mid- winter. Although very vigorous in well-composted, deep soils, this tough little crassula will thrive in clay or sandy soils. Give them a good start with some compost and mulch, and water until established. They propagate easily from seed, from stems and leaves that root and from tiny plants that grow on the tips of the flower stalks.

Earth's little gems - Gasteria glomerata

My newly-acquired Gasteria glomerata on the left sharing a pot with Huernia longituba

I acquired my Gasteria in February this year (2015) by way of an on-line auction on FaceBook and after winterizing inside my house for two months, I was thrilled to discover a small! flower soon after I put it outside at the beginning of spring. I juts can't wait to see it fully open!

Gasteria glomerata is a stemless, compact succulent plant with an unspotted but slightly roughened grey-green leaf surface. Leaves grow in a single line (distichous), but the plant clumps up freely to make a mat. Already I see a baby peeping through on the left! It is native to the Eastern Cape of South Africa.
.

G. glomerata is a rare endemic confined to the lower Kouga River, now part of the Kouga Dam. Although it is rare, its status is not threatened at all due to its cliff face habitat and it is protected within a reserve. The seed is also dispersed world-wide and the plant is commonly grown in many collections. Its ease of propagation ensures that it is not necessary to collect plants from the wild.

The terrain of Gasteria glomerata is rugged, inhospitable and the plants occur on sheer, vertical, shady, south-facing rocky ledges (altitude 500-700 m), in minerally poor, slightly acid quartzitic sandstone soils. Gasteria glomerata is pollinated by sunbirds. Its fruiting capsule, opens from the top to release the flattish seeds. The fleshy leaves store water and are therefore drought tolerant, making this an ideal water-wise garden plant. Even though its habitat on the cliffs is very exposed, and is bone dry at times, the plants receive enough water from seepage for survival.
.

It is popular due to its horticultural value, and can be grown in small containers or in succulent plant gardens and is easily propagated from leaf cuttings or seed. It is a slow growing, but long-lived species. Leaf cuttings should first be allowed to dry and heal by placing them on a cool windowsill for at least three weeks. The basal part should preferably be treated with a fungicide. Plant the leaves in an erect position or lying on their side in sandy soil. Rooting is rapid and young plants can be harvested the following season.

Carpobrotus

I used to have stretches of this wonderful ground-cover in my last garden. This easy-to-grow succulent, native to South Africa, is a wonderful ground-cover, ideal for low-maintenance and water-wise gardens.

Leaves are eaten by tortoises. Puff-adders and other snakes such as the Cape Cobra are often found in Carpobrotus clumps where they ambush the small rodents that are attracted by the fruits. Flowers are pollinated by solitary bees, honey bees, carpenter bees and many beetle species. Flowers are eaten by antelopes and baboons. The clumps provide shelter for snails, lizards and skinks, so it’s a wonderful plant to have if you want to attract wildlife to your garden.

CARPOBROTUS C. acinaciformis (sour fig, elandsvy, goenavy, Hotnotsvy, strandvy, suurvy ) has purple flowers, robust, short, greyish green, sabre-shaped leaves and tasty edible fruits, used to make a delicious jam, and grows in coastal sands usually close to the sea, in the Western Cape, from Saldanha to Mossel Bay (South Africa).

Carpobrotus juice (from leaves) can be used as a mild astringent. When mixed with water the juice can be used to treat diarrhoea, dysentery and stomach cramps. It can also be used as a gargle for sore throat and laryngitis, and mild bacterial infections of the mouth. The leaf juice can also be used externally, much like Aloe Vera for burns, abrasions, open cuts, grazes, mosquito bites and sunburn. It is also used to treat ringworm, eczema, dermatitis, herpes, thrush, cold sores, cracked lips, chafing, skin conditions and allergies.

CONSERVATION STATUS 
Carpobrotus edulis is not regarded as threatened in its native habitat, but it is invading natural areas in other parts of the world and threatening the survival of other species. In California, where it has been used since the early 1900s to stabilize the soil along railway tracks and roadsides and as a garden ornamental, it has naturalized and is invading coastal vegetation from north of Eureka to Rosarita Bay. It is known as the highway ice plant in the USA. It has naturalized along the west coast of Australia from Perth to Albany where it was also used for soil stabilization and is known as pigface. It has naturalized in parts of the Mediterranean and on the south coast of England.
