Kalanchoe rotundifolia (Haw.) Haw.

Family: Crassulaceae

Common names: Common Kalanchoe, Nentabos, Plakkie (Afrikaans) and umadinsane (Zulu).
.

Kalanchoe rotundifolia is a brittle succulent plant which grows up to 1m tall under favourable conditions. It is a common, orange-flowering species with a slender stem. It has fleshy, rounded or lobed leaves that are 2.5cm broad and are clustered at the base of erect stems. It must be noted that some of these plants, although with the species name rotundifolia, have leaves that are not round. They were grouped together because they had other similarities. The genus Kalanchoe typically has a tubular flower. Flowers are borne in an inflorescence with a long erect stalk. The flat-topped inflorescence consists of yellow or orange flowers and often become red and conspicuously twisted when old. The flowering period occurs through autumn and early winter (February until June).
.

It is a delightful little plant that puts up a brave show in clumps among trees and shrubs. The robust red flowering specimens are rewarding garden plants, flowering for many weeks. Kalanchoe rotundifolia is traditionally used by the Zulu as a charm to make one invisible.

This is an easy plant to propagate from both seed and cuttings. The seeds of these plants are very fine and must be collected as soon as they are ripe before they disperse. The best time to sow these seeds will be early spring in order to give them plenty of time to grow before late autumn. Sowing may be done either in seedling containers or directly into the garden.

Ideal cuttings for propagating are semi-hardwood and soft tip cuttings. Cuttings should be planted into river sand and there is no need to apply root-stimulating hormones. Each leaf is capable of producing a new plant when it drops to the ground. The rooted cuttings or seedlings must be planted in dry, shady conditions.

This is a good plant for a low maintenance and waterwise garden. In summer rainfall regions there is no need to water as rain will be sufficient. Kalanchoe rotundifolia will successfully seed itself in the garden and once it is established it will persist for many years.

This plant is a danger to livestock, notably goats and sheep, as it contains the same or similar poisonous substances as the Cotyledon species that cause loco disease or nenta.

Plant Kalanchoe rotundifolia in light shady areas, in the shade of plants or in a sunny spot that gets at least some shade. These plants are particularly attractive when they show up in odd places in the garden and are very useful in the wild garden. They will grow in almost any soil as long as it is well-drained. Too much water and shade will hinder flowering. - See more at: http://kumbulanursery.co.za/plants/kalanchoe-rotundiflora#sthash.SbLj5cMK.dpuf

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.

Succulents in hanging baskets

If you are someone who has always been partial to hanging baskets, yet you like cacti and succulent plants, you might be wondering, “What are my choices?” There are plenty of succulent plants that hang down that are perfect for hanging baskets.
.

.
Last spring I planted a few succulents in a hanging basket that used to contain Plectranthus verticilatus, which unfortunately died during winter. The story goes that, as long as your 'money plant' (Plectranthus)  grows well, you'll never be short of money, and I had my plant for years. When it died last winter, I must say I started getting very worried! he he!
.
I used a few Echeveria imbricata, Echeveria elegans, some Gasteria and a few sprigs of Crassula imperialis. They have all survived the winter and really filled the basket nicely! Hanging from a wooden beam on the patio, they get morning sun and late afternoon sun and very little water.

More succulents you can use :
.
Burro’s tail (Sedum morganianum)
 
Ragwort vine (Othonna capensis)  – This is one of the creeping hanging succulent plants. A member of the daisy family, this is not as common as some succulents. But, it has much to offer. Native to South Africa, this creeping plant features slender, trailing stems. These can eventually reach several feet in length. The shiny, green leaves are usually in clusters. Spindle-shaped, these look as if they are suspended on the stems. The yellow blooms, which look like daisies, need sun to open.

String of hearts (Ceropegia woodii) - being a succulent it is very forgiving to being under-watered.

String of pearls (Senecio rowleyanus)
 
String of nickels (Dischidia nummularia) - This trailing succulent plant has interesting foliage that screams for attention. It consists of round grey-green leaves which are flat and reminiscent of little coins (about nickel size) hanging  from a string.

Rattail cactus (Aporocactus flagelliformis)

The Rattail cactus is another succulent that actually prefers a hanging basket, as the trailing stems can get several feet long.

Vygie (Mesembryanthemum Lampranthus)

Vygies is another creeping succulent that does well in a hanging basket. I've got mine in a little basket on a plant stand on my patio and is already starting to hang down. I'd like to plant him in a hanging basket, but would just have to find the perfect sunny spot in the garden to hang him.

I'm sure there are many more species that can be used in your basket, so just use your imagination and give them a try, you might be pleasantly surprised!

Sedum rubrotinctum

Sedum rubrotinctum has small, glossy, bead-like leaves that take on a reddish hue in full sun. In a climate with very strong sun this Sedum needs light shade. Leaves tend to drop off the sprawling stems and root to form new plants but stem cuttings can also be taken. The leaves are considered poisonous if ingested and their sap may irritate the skin. Heads of yellow flowers, with reddish sepals in strong light, are produced in the Summer.

Commonly known as the jelly bean plant, or pork and beans, it is a species of Sedum from the Crassulaceae family of plants. It has been classified as a hybrid plant — of Sedum pachyphyllum × Sedum stahlii — named Sedum × rubrotinctum.

A newly-planted stem of S. rubrotinctum

S. rubrotinctum, originating in Mexico, is cultivated as an ornamental plant for planting in gardens and as potted plants. It is grown very easily and tolerates all types of soil except for those that are poorly drained. It grows very well in summer, can take variations in climate, although it is not frost-tolerant. New plants may be grown from leaves (or beans) that drop off or are separated from the stem and laid on the soil.

Water the jelly bean plant more in the spring and summer, but still let it dry out in between waterings. Plant in well-draining potting soil and never let it sit in water. Fertilize in the spring and summer once a month with a cactus and succulent fertilizer. No insect pests or diseases are known to severely attack this plant.

Be careful when touching this plant as it can irritate some people’s skin. Also make sure that no pets or children eat this plant. Jelly bean plant leaves are delicate and can fall off easily.

My little green cactus

My little green cactus stands out there on the balcony,
What do I need red roses for, what do I need red poppies for?
And if some rascal says something ill-mannered,
Then I get my cactus and it pricks, pricks, pricks!
My little green cactus stands out there on the balcony,
Hollari, hollari, hollaro!

Aloe striatula

Family: Aloaceae
Genus: Aloe (AL-oh)
Species: striatula (stree-AT-yew-luh)

  
From the wilds of South Africa comes this amazing species with upright stalks of 1" wide, dark green foliage. In warmer climates, the stalks can reach in excess of 3' tall. The larger stalks tend to arch outward with age due to excess weight...as do we. In early summer, the clumps are topped with amazing scapes of orange-yellow bells. This is one for the plant nut who likes to push the limits of hardiness.

Aloe striatula is a strong-growing climbing aloe whose native habitat is in mountain tops south of the Karoo region of South Africa. A tough and hardy plant, Aloe striatula is popular in gardens throughout the world. It can grow to a 6 feet tall shrub.

Aloe striatula gets its name from its distinguishing markings -- dark green stripes on its stems and leaf sheathes, in Latin "striatula" means "striped". Also known as the “Coral Aloe”, Aloe striatula is quite cold and heat tolerant. Its leaves are thin, dark green and strongly recurved, with small white teeth on their margins.

Aloe striatula is one of the hardiest aloes, and will tolerate much colder temperatures than most Aloes, including frost and even some snow, but it prefers full sun and well-drained soil. In the Eastern Cape it is often planted along the boundaries of kraals, as it naturally forms a well-shaped and hardy hedge. Like other climbing aloes, it can easily be propagated by cuttings (truncheons) as well as by seed.

The brilliant yellow inflorescence emerges in late fall through winter and rises above the foliage.

When planting in the garden you will need to provide Aloe striatula with a free-draining soil as it can be prone to attack from fungal infections if the roots become too wet. Dig in plenty of horticultural grit and sand to the soil of required but avoid planting in heavy soils or soils that are prone to water logging.

If suitable ground does not exist then consider planting into a pre-formed mound of free-draining soil, a raised bed or even a suitably sized container. For the container, use a good quality compost but with a 50:50 mix of horticultural grit and sand.

Although closest to the rare and unique Aloe commixta of Table Mountain, Aloe striatula is part of a whole group of related climbing aloes that grow throughout Southern Africa, the "Macrifoliae" Aloes. Other species in this group are: Aloe ciliaris, Aloe tenuior, Aloe gracilis, Aloe juddii, Aloe decumbens, and of course commixta and striatula itself.

Crassula Perfoliata ssp. falcata Up-date

Since I acquired my Crassula falcata in January this year, I've been patiently waiting for it to flower. I was told that a young plant takes ages to flower, but just two months later, in the first week of March I was blessed with the first bud!

Endemic to South Africa, from the Cape Province, they grow to approx. 2 feet (0.61m) tall. The blossom started off with a light pink but soon turned into a sparkling, striking red.

12th March 2015

16th March 2015

By the 4th May I was rewarded with this beautiful flower!

The flower is actually quite heavy and soon leaned horizontal and I was scared it might break off. But turning it to face the sun solved the problem as the plant reacted quite well and started to get up straight again.

Over the past two weeks of June, the bloom has started fading and this summer I'm looking forward to some more lovely flowers!

Crassula falcata plants grow to 2 feet tall. Their small scarlet red flowers grow in a large cluster, rising dramatically above the plants' leaves in summer, giving a beautiful showing for 6-8 weeks. They flower smells like cinnamon and can bloom twice per year, attracting birds and other pollinators.

Echeveria harmsii

Family : Crassulaceae
Botanical Name : ECHEVERIA harmsii
Plant Common Name : Plush Plant

This soft little fuzzy succulent has beautiful leaf colour that adds interest to small gardens and pots. It is a rosette-forming species that hails from northern Mexico. This evergreen forms small asymmetrical rosettes comprised of fleshy, football-shaped leaves with a burnished-red cast along the leaf edges. The rosette will occasionally send out pups, or lateral plantlets. As these accumulate, the plant develops a mound-like habit.

This succulent has large, beautiful flowers, but it is not a heavy bloomer. In spring it sends up stems topped with orange, bell-shaped flowers with golden throats. Each stem may include many flowers that open at different times for a longer season of colour. The blooms are highly attractive to hummingbirds.
Like most succulents, this plant prefers full sun and needs very porous soil, whether grown in a pot or a frost free rock garden. As plants age, they grow rangy but this can easily be remedied with careful pruning. The cuttings root easily in moist sand. Watering should be done sparingly as this is a very drought tolerant plant. Feed it occasionally from spring to summer occasionally with a liquid fertilizer solution at half strength.

This one started flowering shortly after I put out out in the sun in January, but I have just brought in for the winter as I'm not sure how it will handle the frost we get here.

Cotyledon orbiculata

Family: Crassulaceae
Common names: pig's ear (Eng.); plakkie, platjies, varkoorblare, varkoor, kouterie (Afr.)

I was lucky enough to find this lovely specimen at Sterlig Nursery in Roodepoort in January. It will be spending the winter inside with some of my other succulents and then, in spring, go into the new rock garden I'm planning.

This succulent plant has thick leaves which may vary from green to grey, often with a red line around the margin. Cotyledon orbiculata has five varieties, based on differences in leaf and flower shape. The variability of leaf size, shape and colour is also influenced by the immediate environment. Selected forms in cultivation have been given names such as 'Elk Horns' or 'Silver Waves'.

Flowering time is mostly in winter from June-August, but in the winter rainfall areas such as the Western Cape, it is often in midsummer. The colourful, hanging, tubular/bell-shaped flowers are carried in clusters on the ends of an elongated flower stalk. They are mostly orange-red , but yellow flowering forms are also occasionally found (Ernst van Jaarsveld pers. comm.).

Distribution

Cotyledon orbiculata is widespread throughout South Africa, but is usually confined to rocky outcrops in grassland fynbos and karoo regions. Black frost will damage the flowers, if planted in an unprotected spot, but the plant itself will tolerate moderate frosts.

Ecology

The brightly coloured flowers attract bees and birds, which feed on the nectar of the plant. The silver-grey leaves of some forms owe much of their attractive colouring to a powdery white coating which may assist in reflecting much of the sun's heat to prevent excessive water loss from the thick succulent leaves.

Uses and cultural aspects

This is a well-known medicinal plant. The fleshy part of the leaf is applied by many South Africans to soften and remove hard corns and warts. The Southern Sotho use a dried leaf as a protective charm for an orphan child and as a plaything. In the Willowmore District, the heated leaf is used as a poultice for boils and other accessible inflammations, in particular, earache.

Growing Cotyledon orbiculata
This is an easy to grow plant suitable for a number of places in the garden. Cotyledon orbiculata is an ideal plant for the rockery, but also grows well as a pot plant placed on a veranda (stoep). It will also add texture and form to the well-drained flower border. When planted as a pot plant, good drainage is important. It is often found in full sun, but also grows well in semi-shade under trees. This is an ideal plant for the water-wise gardener.


Plants may be grown from seed, but take care in the early stages not to over-water. The best time to sow the seed is in spring, and they should be kept moist, not waterlogged. Once the seedlings have reached 20-40 mm they can be transplanted.
Taking tip cuttings is the fastest method of increasing plant numbers; they must be kept fairly dry to prevent rotting. Once the tip cuttings have rooted they can be transplanted in a medium of 2 parts gravel to 1 part compost.

This plant has few pests, but it may be attacked by snails in the garden.

Grass Aloes

In the hope of reaching the moon

men fail to see the flowers

that blossom at their feet.

- Albert Schweitzer

I found a large clump of Grass Aloes (A. verecunda) not far from home on the road to Magaliesburg (Gauteng, South Africa), flowering profusely after all the veld fires we have had in winter, spread out over the charred landscape, providing bursts of red colour.

Grass Aloes are an appealing group of deciduous aloes, and loses all its leaves in winter which only reappear after the first rains in Spring. The plant has thick fleshy roots in which it stores water during the dry winter months.. As the name implies, they grow mainly in grasslands subject to winter fires. Their leaves and colours resemble their habitat, making them difficult to find when not in flower. These largely miniature aloes have very attractive flowers, making them desirable, if difficult, plants to cultivate. Their growing pattern is closely related to the winter fire cycles of the veld here in South Africa, some species responding directly to burning and producing leaves, flowers and later seed after such events. Tare often burned during winter and then re-sprout with the onset of spring.

This well known grass aloe is commonly found along rocky ridges and rocky slopes on the Witwatersrand and Magaliesberg as well as in mountainous areas of the Northern Province and Mpumalanga. In years gone by it was even more prolific, but numbers have been greatly reduced due to development on the ridges and from harvesting by succulent collectors. A number of different forms are found throughout its distribution range.

Grass fires used to be less frequent in earlier centuries. They were initiated by lightning strikes, on the whole, at the beginning of the rainy season in September and October. These fires were ideal in that they cleared the habitat of moribund grass and other vegetation just before grass aloe species initiated their growth cycles.

Fires are more frequent nowadays and may occur at any time during the dry winter months from May until late spring, October. Plants are as a result, left exposed to harsh conditions for many months before they start to grow. Some species are even starting to appear on the endangered species list.
