A garden without wildlife is hardly a garden at all

Ever changing ever new

Our average affluent north Durban suburban garden owner has the most  uninteresting sterile garden possible planted to a very limited number of sterile unchanging plants such as Philodendron selloum cv. Xanadu, bright coloured crotons Codiaeum variegatum, dust collecting Dianella tasmanica variegata, Ophiopogon japonica, Ophiopogon jaburan variegata a never changing boring landscape. Masses of boring single straight stemmed palms, yellow leaved Duranta erecta Sheena's Gold ™ which have been trimmed into hedges, balls and who knows what, to me a plant that is this colour is  critically ill and needs to be removed. All to be finished of with horrible gaudy purple border bedding plants such as purple setcreasea Tradescantia pallida and Rheoe Tradescantia spathacea

Croton Codiaeum variegatum

The Croton Codiaeum variegatum above is very clearly a magnificent plant that has its uses but it never changes how it looks which in time becomes overpowering and boring and in particular it is sterile, it attracts no wildlife at all it could very easily be replaced in the garden with an identical copy made of plastic and few if any people would be any the wiser. These magnificently colourful plants most certainly do not bring life into the garden.

Change and variety are the spices of life and that applies in particular when planning a garden either exotic or indigenous if one would like to create tranquillity in the garden and to provide the greatest of benefit for the user and observer.

In a Proudly South African living garden planted to our local South African plants there are never two days that are the same, it is ever changing, ever interesting, the  bright yellow bloom of a Hibiscus calyphyllus or Hibiscus surattensis here this morning gone this afternoon a flush of blooms the following day.

 

Hibiscus surattensis  bright and beautiful ever changing never the same.

Dietes grandiflora and Dietes iridioides which come to their full glory for a single day in the spring and early summer months after a drop in atmospheric pressure, then wait for the next drop in pressure to repeat the spectacle. A blaze of blue from the Agapanthus Agapanthus praecox spp.orientalis for a few weeks during midsummer, a blaze of orange from the aloes during the winter to be followed by a blaze of red from the coral tree Erythrina lysistemon announcing the early spring that attract birds and insect

An interesting and colourful bug sitting on a flower, interesting colourful insects everywhere you look in the garden.

A spectacled Weaver Ploceus ocularis building its nest on a Strelitzia tree Strelitzia nicolai outside my kitchen door.

These things are seldom seen and experienced in your regular traditional Durban garden with its mostly sterile tropical and subtropical plants that appear to never change from season to season, day to day, week to week, year to year, never changing always the same. Many of these gardens may just as well be made of brightly coloured plastic and concrete for all the life that they bring into the garden. Well manicured bright un-natural colours, coarse textures.

  

A well designed garden planted exclusively to our local indigenous plants will be green and tranquil full of interest, full of beauty, with green that comes in every texture, form and shade is ever changing ever new. Every day there is a new surprise, as flower buds burst open to expose a splash of brilliant colour, sometimes lasting only a few hours and sometimes weeks on end then back to the tranquillity of green to soothe the soul.

A very easy plant to propagate and to grow is this magnificent pendulous Gladiolus cruentus a rare critically endangered local gem seldom if ever seen in cultivation in South Africa

A brightly coloured sun bird gently alights on a leonotis intermedia to sip nectar before flitting off to another brightly coloured plant or to hawk a passing insect in mid air.

During the day bright orange paradise flycatchers with their long tail feathers dart out under the canopies of the trees to catch a passing fly and as the sun dips its head below the horizon tiny little bats appear doing tight aerobatics under the same trees to hawk the insects that they feed on.

I look out the window and see a bright coloured Locust Zonocerus elegans which feeds on the milk weed plant Gomphocarpus physocarpus which is also the host plant to the African Monarch Butterfly.

A bronze back manikin alights on a grass stem to pluck a seed head of Panicum maximum to build his nest,  later I see him return to collect the fluffy flower heads of natal redtop grass Melinis repens to line it with.

A bright red African Fire Finch arrives on the ground just outside my kitchen door to look for seed and insects.

The sound of the Crested Barbet that has his home in a nest box I placed in a tree directly opposite my kitchen window only a few metres away, the sound of  Painted Reed Frogs in a small pond of arums in the evening a garden which is a haven for wildlife in all its forms both day and night with interest without end, is this not what a garden should be.

Painted Reed Frog Hyperolius marmoratus

To maximise the life in a garden it must be planned with as large a variety of interesting local plants to create habitat, which provides shelter, breeding and feeding opportunities for all manner of creatures both great and small. Thereafter we need to do little more to encourage life into our gardens, if the conditions are right wildlife will come and stay of its own. The bigger the variety of plants and habitat types the greater the numbers of creatures that will be attracted. The garden must have water, it must have lawn to serve as green pathways and to separate the different elements of the garden. Do not forget a bench here a table and chairs there so that one can sit and relax and enjoy the garden and its wildlife.

African Monarch butterfly Danaus chrysippus on the flower of it´s host plant the Milk Weed Gomphocarpus physocarpus

There is no reason why a garden that is maximised for wildlife should not be planned and planted to the highest standards of landscape design incorporating only our local plants and a slightly different order to what has traditionally been accepted here in South Africa and much of the world.

When it comes to maintenance the garden must still be well manicured just as the sterile traditional garden in particular at the entrance and near to the house but it will need to be a slightly different order, the beds will still need to be edged, the lawn mowed and the weeds removed, no one wants to be greeted by a mess. However the maintenance must not show a misguided sense of order it must not be carried out with sensitivity and not to the detriment of the life in the garden.

All the photos that I used in this article have been taken in my own garden at Mount Moreland north of Durban.

Forest Toad Tree Tabernaemontana ventricosa an ideal tree for a small garden

Forest Toad Tree

Tabernaemontana ventricosa

Umkhahlu, Ukhamamasane (Zulu)

Belongs to the plant family Apocynaceae.

Natural Distribution and Habitat

Tabernaemontana ventricosa  has a disjunct distribution from Ghana, eastern Nigeria, western Cameroon, eastern Democratic Republic of the Congo, Kenya, Tanzania, Zambia, Mozambique, Zimbabwe and South Africa in the coastal areas of KwaZulu-Natal where it grows in riverine forests and the forest under storey.

Description 

This small to medium-sized tree can reach a maximum height of 15 m, but averages between 4 and 8 m. Tabernaemontana ventricosa can have one or more straight trunks with smooth greyish-brown bark. The tree is low branching with smooth, dark green young branches turning a pale brown when mature. The leaves are large oblong and shiny dark green in colour, the flowers are salver-shaped, white and sweet smelling. The unusual fruits have two pods joined at the base they are dark green and smooth, sometimes with wrinkles and light green speckles or markings they split open to reveal fleshy orange pulp with embedded seeds in June to August.

Use in the landscape

Tabernaemontana ventricosa with its small size, clean tidy growth habit, glossy dark green foliage, attractive sweet smelling white flowers and unusual fruits, is excellent for the landscape designer of gardener to plant in any garden or landscape design. For those wanting to plant it to bring nature back into their indigenous garden it is an excellent choice because apart from being an ideal landscape feature plant it also attracts birds, insects and small mammals into your garden.

Although Tabernaemontana ventricosa grows naturally mostly as an under story plant and prefers shade to partly shady conditions it will grow in the full sun in a garden if it is sheltered from the wind and it gets plenty of water, where it will flower much more profusely than if grown in shade.

Tabernaemontana ventricosa is frost sensitive, preferring more tropical areas with mild winters.

Tabernaemontana ventricosa will happily grow in wet places where many other plants may not grow.

Ecological importance

Birds, animals such as fruit bats and monkeys eat the fruit. The leaves are browsed by game in particular bushbuck, the sweet smelling flowers attract various insects.

Propagation and Growing

Tabernaemontana ventricosa can easily be grown from fresh seed and grows relatively fast under favorable conditions.

Tabernaemontana ventricosa seedlings grows best in humus rich well drained sandy soils.

Plant in a large hole and mix in a good amount of compost, well rotted manure, and a balanced fertiliser. Mulch well and water regularly, especially during the first year or two for optimum growth.

Cultural Uses 

The bark of this tree is said to be used for bringing down a fever, the latex is applied to wounds and sore eyes to promote healing and in KwaZulu-Natal the seeds, bark and roots are used to treat nervous complaints and high blood pressure.

The pulp of the ripe fruit is edible.

No proudly South African home should be without a Begonia dregei

Baobab-Begonia, Maple-leaved begonia

Zulu: iDlula

German: Baobab-Begonie

Begonia dregei plant with flowers

Begonia dregei is a South African endemic occurring naturally from

East London to Durban.

Begonia dregei is rare occurring in forests, on rocky, mossy cliffs and steep banks, from the coast to 1 219 m. According to the IUCN listing Begonia dregei is endangered.

Begonia dregei is a spectacular evergreen shade loving perennial that makes an excellent indoor or outdoor pot plant.

Begonia dregei caudex

Begonia dregei is a tuberous, fleshy perennial that grows with a swollen stem base known as a caudex. The caudex is usually mostly out of the soil. The stems grow from the caudex. During long dry periods Begonia dregei can loose all of their foliage or even die down to the caudex to recover quickly after the first rain or watering. 

  

The leaves are generally small (50–80 x 20–35 mm), asymmetrical, lobed often with large white spots when young and widely toothed. The 40–90 mm long leaf stalks are green or reddish, there is however a very large variation in leaf size and form from population to population.

The leaves look much like those of the Maple Tree Acer spps. which gives it one of it´s common names the Maple Leaf Begonia.

The far more spectacular male flower of Begonia dregei

The flowers of Begonia dregei are fragrant and produce a delightful show. In cultivation Begonia dregei flowers for almost the entire year producing small white to pinkish flowers with a bright yellow centre.

The male and female flowers occur separately on the same plant which are inter fertile so if one only has one plant it will still produce large amounts of fertile seed. The male flowers can be recognised because they have two petals and the female flowers have five.

The far less spectacular female flower of Begonia dregei

I have grown Begonia dregei for many years having found the first specimen growing in the Kloof area about 25 years ago. The plants that I am now growing were propagated from a single specimen that I found growing at scary cliffs at Mount Moreland in December 2007

  

Over the years I have found Begonia dregei to be very easy to grow and quick-growing from seed or cuttings.

Seed is best sown in early spring or summer in a moist well drained medium, plant sparingly because the seed is very fine and germinates readily coming up like hairs on a dogs back. The fine seed from my plants is distributed by the wind and seedlings pop up on a regular basis in the pots of other plants that I am growing in particular my orchid plants where they germinate well on little or no soil. Cuttings are far easier to grow for the average gardener they do better in the warmer months but can be grown just about any time of year by the more experienced grower.

Begonia dregei seed capsules the one on the right has already split and has released much of the seed

Begonia dregei grows well in light shade but will also grow in deep shade as well as where they get. a moderate amount of sun for part of the day. Plants grown under brighter conditions flower far more profusely.

I have found Begonia dregei rewarding and easy to grow as a pot plant where I have usually grown them in hanging pots together with my orchids they will also grow well in the ground

The large caudex makes Begonia dregei look a lot like a miniature baobab tree Adansonia digitata.

Begonia dregei is mostly pollinated by bees.

The caudices of Begonia dregei are used for traditional medicine.

  

Begonia dregei is another one of our floral gems that is very well known, treasured and grown in very large numbers abroad but is hardly known or grown here in South Africa which is rather disgusting of us Eurocentric South Africans for us not to treasure and be proud of that which is South African.

Sun hibiscus no garden should be without one

Hibiscus calyphyllus, Sun hibiscus, lemon-yellow rosemallow 

German: Sonnen-Hibiskus

  

Hibiscus calyphyllus flowers are bright sulphur yellow with a deep maroon centre.

Hibiscus calyphyllus occurs naturally from southern East Africa up the East African coast to Sudan, Eritrea, Ethiopia and Yemen. Hibiscus calyphyllus also occurs in tropical Central Africa, Madagascar and the Mascarene Islands.

The natural habitat of Hibiscus calyphyllus is open bush, thickets and forest edges where it is often found along rivers.

Hibiscus calyphyllus is a local medium sized shrub that has large, bright green, soft and velvety leaves, giving it a lush tropical appearance with 12 cm flowers which are bright sulphur yellow with a deep maroon centre. 

Hibiscus calyphyllus grows to 1-1.5 meters tall and is often prostrate and straggly in the wild.

Hibiscus calyphyllus is a very rewarding showy garden plant for both the exotic tropical garden as well as in the indigenous garden that I have grown in my own gardens in Durban for at least the last 30 years. Unfortunately as is the case with so many of our magnificent local plants it is still hardly known and grown in South African gardens although it is very well known and widely grown garden ornamental throughout the tropics and subtropics.

Hibiscus calyphyllus has been in cultivation abroad for a long time having been first offered for sale in England in 1883 under the name Hibiscus chrysanthus with Port Natal, Cape Colony identified as the source. In addition Hibiscus calyphyllus seeds were sold in the United States at the beginning of the 20th century under the name Hibiscus Giant Yellow.

 Hibiscus calyphyllus has large, bright green, soft and velvety leaves

Hibiscus calyphyllus grows best in fully sun to light shade. Hibiscus calyphyllus is a relatively fast-growing plant, providing that it is planted in fertile, rich and well-drained soil well enriched with organic material. The soil pH should range from mildly acidic to neutral.

Although Hibiscus calyphyllus is very drought resistant and can grow under very dry conditions, to do well in the garden it needs a moderate amount of water on a regular basis.

In cultivation it is good cultural practice to prune Hibiscus calyphyllus back after the main flowering season to encourage bushiness, light pruning during the summer growing period encourages flowering.

In South Africa the leaves of Hibiscus calyphyllus have been traditionally used as toilet paper which could be a good thing to remember when hiking out in the bush.

In East Africa, the leaves of Hibiscus calyphyllus are eaten as a vegetable

and in the Okavango Delta the flowers are cooked and eaten.

Attracting Frogs to your Proudly South African Garden

Frogs are under threat worldwide, from habitat loss, pollution, and, more alarmingly, a new deadly parasitic fungus known as amphibian chytrid.

Greater Leaf-folding Frog Afrixalus fornasinii

Frogs and toads play an important role in the ecology of the garden, where they eat insects which make up the largest part of the diet of frogs, they also eat slugs, earthworms and millipedes

Painted Reed Frog Hyperolius marmorata

If you want to play your part and ensure their survival in your own back yard, there are several things you can do to create a frog-friendly garden.

.

Natal Forest Tree Frog Leptopelis natalensis

Build a pond using a sheet of thick plastic laid into a depression covered with a suitable layer of soil or out of concrete. It need not be large to be effective and it need be no more than 30 cm deep. In fact any container big or small that holds water can be used to attract frogs. Water plants need to planted into the pond to provide shelter and food for tadpoles.

Even more important than the pond itself is the area around it, so suitable local indigenous reeds and other marginal aquatic plants need to be planted in and close to the pond which will then provide an attractive habitat for reed and other frogs.

Natal Dwarf Puddle Frog Phrynobatrachus natalensis

In addition local indigenous shrubs, groundcovers and grasses must be planted nearby to provide additional shelter and to attract insects slugs and other food for the frogs to feed on. The more indigenous plants you have in your garden the more habitat you will provide to make it attractive to frogs. A garden full of sterile exotic plants will attract very few if any frogs.

Red Toad Schismaderma carens

Because all frogs breathe partially through their skin, they are particularly sensitive to toxic chemicals in the environment therefore you should avoid using insecticides in the garden wherever possible.

African Common Toad Amietophrynus gutturalis

All the frogs photographed above and many other species are resident and breed in my own garden in Mount Moreland in a number of small and large tubs, shallow plastic trays, plastic dirt bins and concrete ponds which have been place in strategic positions within the plants in the garden.

Lily Grass or Weeping Anthericum

Anthericum saundersiae Synonym. Chlorophytum saundersiae

Anthericum saundersiae is an excellent and very versatile landscape bedding plant that can be grown in the full sun semi and even full shade it is an asset to any landscape design in particular where one would like to plant a productive plant the brings in vast amounts of wildlife into the landscape or garden.

Anthericum saundersiae plant is named after Katharine Saunders plant collector and botanical artist who was born Katharine Wheelwright (1824-1901) in Tansor, Northamptonshire, England  she emigrated to Tongaat, Natal with her husband James who later became the sole proprietor of the Tongaat Sugar Estate in 1860.

I first collected Anthericum saundersiae which I found growing in full sun at the Treasure Beach grasslands in Durban in the late 1970`s. The tiny insignificant single stemmed specimen that I collected grew rapidly under my care and soon started to produce vast amounts of seed which germinated readily under the ideal conditions that I gave it and in no time at all I had large numbers of this delightful little plant. Anthericum saundersiae produces a profusion of little white star like flowers on long thin, arching stems from mid winter into late summer. Some years later I gave a number of my still unidentified plants to Geoff Nichols who took a specimen to the Natal Herbarium at Botanic Gardens where it was identified as Anthericum saundersiae. I grew and sold Anthericum saundersiae in my own nursery in small numbers but after they found their way to the Silver Glenn indigenous plant nursery they were propagated in large numbers making them much more available to the public.

In 2001 I went to stay in Germany where I became familiar with a very similar and popular specie Anthericum ramosa Syn. graminifolium so I was not at all surprised when I returned to South Africa seven years later and found Anthericum saundersiae growing in their countless thousands in nearly every new garden planting in and around Durban. Whether those plants now in cultivation came from the one tiny specimen that I collected way back in the 1970`s or from another source I do not know and probably will never know but the likely hood is certainly high that they did.

Anthericum saundersiae is a very productive trouble free garden plant that grows to about 700 mm which is ideal for the natural garden in that it attracts vast numbers of insects in particular large numbers of bee species from the very smallest to large bumble bees that when they land on the flower they weight them almost down to the ground causing them to bob up and down as they move from flower to flower setting the plants in motion as if they are dancing. I have observed that the foliage is also loved by Scrub Hares, domestic rabbits and in particular Egyptian Geese.

Although Anthericum saundersiae prefers to grow in full sun in fertile sandy soil it is a very versatile plant that will grow under almost any conditions in most soils from sand to heavy clay soils in frost free areas.

Anthericum saundersiae propagates very easily and profusely from seed but can also be subdivided when seed is not available. Seed germinates best in raised seed beds or directly on the ground in prepared sandy soil with a little very well rotted compost added, poor results may be obtained if seed is planted into a bark based growing medium in seed trays

Attracting dragonflies to your Proudly South African Indigenous Garden

It has been stated by environmental scientists that Dragon Flies in the garden are an indicator of a healthy well balanced environment in addition their sensitivity to habitat quality and their amphibious life cycle make dragonflies well suited for evaluating environmental changes.

Machado’s Skimmer Orthetrum machadoi (female) taken in my garden at Mount Moreland

They are carnivorous not only in the adult stages of their life cycle, but also in their larval stage. The dragonfly is considered as one of the best agile predator around.

During their nymph phase, when a dragonfly has to remain underwater, it eats aquatic insects, worms, mosquito larva, small fish, and little tadpoles. In this phase, it is empowered with a thrust mechanism system to boost its speed while following its prey. It also ejects water from its anal opening to increase its speed in times of need.

They feed on small insects such as bees, ants, wasps, butterflies, flies, and midges. A dragonfly has the ability to move in different directions swiftly. Hence, it can easily out-fly its prey on most occasions

Adult dragonflies often hunt for food in groups, when ants or termites are available in large numbers or when there are swarms of gnats are available in their proximity. Dragonflies keep mosquitoes at bay by feeding on them.

Julia Skimmer Orthetrum Julia (male) taken in my garden at Mount Moreland

It is rather easy to attract these most interesting and attractive insects into a healthy indigenous garden by providing breeding opportunities for them in the form of a natural pond either large or small in fact a tub with a few local aquatic plants is all that it takes to provide a breeding opportunity for dragonflies just as long as no fish are placed in them. There is no need to worry about mosquitoes once the pond had matured and attracted dragon flies as their larvae are voracious carnivores which relishing mosquito larvae.

For biological control to work enough mosquito larvae must survive in the ponds to feed the dragon fly nymphs, which largely feed on mosquito larvae, so a few larvae will always be found in the ponds, however this small number is compensated for a thousand fold by the vast numbers of adult mosquitoes that arrive from other sources that are controlled by the adult dragon flies.

In my own garden I have a number of tubs and shallow containers planted to an assortment of aquatic plants that together with plantings of suitable flowering plants attract very large numbers of Dragonflies to my own garden which act as a very good control for both flies and mosquitos.

Anthericum saundersiae

To help enhance the garden to attract dragonflies the addition of plants like Anthericum saundersiae, Chlorophytum cooperii and flowering grasses which attract large numbers of suitable insect pollinator provide vast amounts of food for these aerial acrobats.

Agapanthus praecox a floral Gem

Agapanthus praecox sups. orientalis

Agapanthus means love flower, the name agapanthus is made up of two Greek words agape love and anthos flower. The Zulu name for this plant is ubani.

Photo taken of a bed of Agapanthus praecox in flower at my home in Mount Moreland

Agapanthus belongs to the plant family Agapanthaceae which consists of only one genus that is endemic to southern Africa, meaning that Agapanthus occurs naturally nowhere else on Earth

This is one of the best known of our South African plants abroad having been first introduced to and grown in Europe since about 1652.

Agapanthus praecox is easy to grow and will even grow in poor soils provided it receives sufficient water in particular in summer. For Agapanthus praecox to perform at its best, it however requires a rich soil with plenty of compost and plenty of water year round in particular in spring and summer. Agapanthus praecox do best in full sun. 

Agapanthus praecox need to be lifted and divided every three to four years to keep them healthy and vigorous this being done just after they have finished flowering. They usually flower best in their first season after having been divided. When replanting reduce the foliage by a third to one half and reduce the roots by two-thirds. Replant immediately and water thoroughly.

Agapanthus are mostly free of pests but can from time to time be attached by the Agapanthus Borer Moth, Neuranethes spodopterodes which is native to South Africa. The larvae bore into the budding inflorescence and as they mature they tunnel down towards the leaves and rhizomes. The Agapanthus borer is often mistakenly referred to as Amaryllis borer Brithys crini pancratii which they are most certainly not. A severe attack can promote rot and may kill the plant.

The introduced exotic European garden snail can at times also do considerable damage if not controlled.

Agapanthus praecox with its neat growth habit and spectacular flowers is an asset and a must for every proudly South African garden and amenity horticultural landscape in the regions where they grow best.

For much of the year the Agapanthus plant does not attracts large numbers of insects or other creatures but when it comes to flowering time they attracts large numbers of bees in particular honey bees to the spectacular blue flowers. And along with the bees creatures that feed on bees such as crab spiders that wait in a flower to catch the fist unsuspecting bee that lands to take nectar and pollen as can bee seen in the photo below.

 A crab spider feeding on a bee that it has just caught.

No proudly South African garden or landscape should be without these most spectacular gems of our South African floral kingdom.

In addition to being spectacular garden plants Agapanthus praecox have many uses in traditional medicine and magic as well as being used as love charms.
