Cape honeysuckle - Tecoma capensis

Unit fairly recently this magnificent very well known shrub was known as Tecomaria capensis

Tecoma capensis this is the colour of the specimens that grow locally in Durban this one having been grown from seed obtained at Burman Bush

Tecoma capensis belongs to the family, Bignoniaceae as do many other very showy shrubs and trees such the well known , Port St Johns creeper  Podranea ricasoliana which is well known and grown in other countries yet is seldom seen or grown here in South Africa. Although a had a very large specimen growing over the roof of my granny flat at my previous house in Durban I have not yet obtained one for my property here in Mount Moreland. The photo below was taken by me in Auckland New Zealand.

Port St Johns creeper  Podranea ricasoliana

The sausage tree Kigelia africana , Rhigozum obovatum, Rhigozum zambesiacum, as well as the foreign Jacaranda are other showy well known members of the family, Bignoniaceae.

Tecoma capensis occurs naturally in thicket and is widely distributed throughout the Northern Province, Mpumalanga, Swaziland, KwaZulu-Natal, Cape coast, Swaziland and southern Mozambique.

In Mount Moreland we have natural populations growing at the south end of the King Shaka Airport and on the cliffs down by the Umdloti River.

Tecoma capensis is well known and cultivated here in South Africa it is also well known and is cultivated in many other areas around the world in particular California in the USA where many colour forms have been developed.  While living in Auckland, New Zealand I found that Tecoma capensis is a very popular hedging plant in most of the older residential areas of the city.

As a child my parents had a Tecoma capensis hedge and I loved to pick the flowers early in the morning before the birds and honey bees got to them to sip the nectar from them.

Flowering time for this shrub is very erratic and often it flowers all year round. Flowers are tubular and bird pollinated, attracting nectar-feeding birds, especially sunbirds as well as honey bees.

Tecoma capensis is an ornamental garden plant commonly used for screening and decorative purposes. It can also be trimmed to form a hedge. It is often planted specifically to attract birds.

I have seen this very dark flowering form growing naturally next to the parks board landing strip at St Lucia

Propagating Tecoma capensis

Tecoma capensis is easy to propagate from hard wood cuttings that in sandy soils can simply be pushed into the ground and watered. They can also be grown from tip cuttings in a mist propagation unit, by removing rooted suckers during the active growth phase, and from seed.

Growing Tecoma capensis 

Cape honeysuckle is an easy to grown and fast growing, scrambling shrub which is evergreen but will loose its leaves if it gets too dry or if the temperatures fall below freezing.  Tecoma capensis produces masses of orange to deep red flowers, there is also a yellow variety which unfortunately does not attract birds to the flowers.

Tecoma capensis will grow in just about any soil. When being planted it will grow best if a good sized hole is dug and is backfilled with a mixture of one third compost mixed with the soil that came out of the hole and a little balanced fertilizer. Please do not forget to water the plants as soon after they have been planted as possible to settle them in, thereafter they will need sufficient water to keep them moist until established. Once well established Tecoma capensis does not need watering as they are extremely drought resistant. In areas that receive frost young plants and larger established plants that have newly been planted out need to protected for at least the first winter.

To keep this shrub clean and tidy and to ensure heavy flowering, it must be pruned back in late winter to promote new growth and flowers.  Mulching with plenty organic compost and the application of a balanced fertilizer after pruning will enhance the growth and flowering.

Tecoma capensis is a must for every garden that has been designed to attract wildlife in particular the garden that has been designed to attract sunbirds because it provides vast amounts of nectar at the times of year when there are far less or no other suitable flowering plants for them to feed on.

Ecological value

Nature conservation starts AT YOUR OWN FRONT DOOR so anyone who is serious about nature conservation and improving the natural environment for as large a variety of creatures as possible simply has to plant a number of these highly productive plants in their own garden.

If you do not have Tecoma capensis growing in your garden and are a doer and not just a talker you will plan today to buy and plant some of these magnificent local South African plants in your garden.

Mature plants can be bought from any nursery that has a good variety of plants for sale.

Aloe pluridens French Aloe

Family    Xanthorrhoeaceae
Subfamily    Asphodeloideae

The specie name pluridens is derived from two words pluri = many and dens = teeth which refers to the many teeth on the leaf margins.

Distribution and habitat of Aloe pluridens

It occurs naturally from the Eastern Cape to just north of Durban in KwaZulu  Natal where it is normally found growing on cliffs and in the shade of coastal bush. It is particularly common in the Port Elizabeth, Uitenhage and the Albany areas where the rosettes may be seen above the surrounding bush.

Description

Aloe pluridens is a very attractive aloe which is usually single-stemmed or may be branched it bears numerous small plantlets on the lower stems. Aloe pluridens is a tall aloe, occasionally reaching up to 5-6 m high. The leaves are bright yellowish to bright green. The leaf margin is armed with numerous teeth. The leaf sap is clear with a strong, rhubarb-like smell.

The inflorescence is attractive, branched with up to 4 racemes protruding above the leaves. The flowers are usually orange or pinkish-red, but a yellow form is also known. Up to three inflorescences may be borne from each rosette. The flowers that are produced from May to July attract sunbirds and bees which in my garden at Mount Moreland often attract Fork tailed Drongos which feed on the bees. This winter the beautiful Scarlet Chested Sunbird which normally occurs much further north has been attracted to the numerous aloes, Kniphofias and Erythrinas trees  that I have flowering in my garden.

Growing Aloe pluridens

Aloe pluridens is extremely easy to grow preferring partial shade for the hottest time of day.  Aloe pluridens will grow in poor soils with little attention but will do much better if it is planted in a large hole that has first been enriched with well-rotted compost and fertilised at least once a year at the beginning of the growing season with a balanced granular fertiliser. 

Irrigation

Although Aloe pluridens is drought tolerant, it thrives and flowers better if adequate irrigation is provided in the summer months.

Propagating Aloe pluridens

Aloe pluridens is extremely easy to propagate which is best done by simply removing the numerous plantlets on the stem and planting them.

The numerous suckers growing on the main stem of Aloe pluridens can clearly be seen

The removal of the side plantlets that are produced in large numbers stimulates the plant to produce more giving a continuous supply of propagating material which makes is possible to quickly produce ever larger numbers of this spectacular aloe. Aloe pluridens can also be grown from seed which they do not produce in large numbers. When vegetatively propagated always propagate from a number of mother plants so that your entire collection does not consist of the clones of one single plant to allow for cross pollination and the production of seed which will hopefully spread to and grow in your neighbours garden.

Landscape value

Aloe pluridens has a high landscape value both as a feature plant where it can be planted as a single plant or as an extensive mass plantings to create a focal point or to define a boundary. Massed plantings provided a brilliant splash of colour during the dry winter months. This aloe is a must for every coastal garden irrespective of whether it is planted entirely to local  indigenous plants or exotic foreign plants

Ecological value

Aloe pluridens is a good source of nectar for birds and bees during the dry winter months

Pests and diseases

Aloe Snout Weevils

Aloe Snout Weevils belonging to the family Curculionidae, the Lesser Aloe Weevil Rhadinomerus illicitus being a particularily destructive specie

The Aloe Snout Weevil is grey, dark brown to black in colour. They are between 15mm-25mm in length. The adult Aloe Snout Weevil feeds on the sap it obtains by puncturing the aloe leaves causing circular lesions 3mm in diameter which leave unsightly marks on the aloe leaves.  The Aloe Snout Weevil lays its eggs at the base of the aloe leaves, the larvae bore into the stem just below the crown of the plant which often causes the entire plant to die.

For comprehensive information on Snout weevil Damage Done to Aloes go to Kumbula Nursery Blog at

http://kumbulanursery.co.za/blog/snout-beetle-damage-done-to-aloes

White Scale insects

The white scale insects become visible as neat white rows on the leaves, especially on the lower surfaces. If untreated, the entire plant will eventually be covered by the insects and may die.

Medicinal uses of Aloe Pluridens

The sulphur-containing compound Pluridone found in the roots of Aloe pluridens has been proven in trials to effectively control coccidia in poultry.

Trema orientalis Pigeon Wood Tree

Trema orientalis is a common pioneer tree which belongs to the hemp (dagga) family, Cannabaceae.

Pigeon Wood Trema orientalis

Trema orientalis has a very wide distribution in the tropical and warm temperate parts of the Old World. It´s range extends from South Africa, through Africa the Middle East, the Indian subcontinent into southern China, Southeast Asia  including the Philippines and Australia.

Over it´s wide range Trema orientalis has many common names which include pigeon wood, charcoal-tree and gunpowder tree

Trema orientalis has considerable ecological significance being a very productive tree

with at least 14 species of butterfly using it as a larval food plant. Many species of birds are attracted to this tree to eat the vast amounts of small berries that it produces almost continuously throughout the year or to feed on the abundant insects which live on these trees. 

Pigeon Wood Trema orientalis berries

In my own garden they are frequented by a large number of bird species which include Black Collard Barbet, Crested Barbet, Yellow Rumped Tinker Bird, Glossy, Black Bellied, Violet Backed and Redwinged Starlings, Purple Crested Turaco, White Eyes, Thickbilled Weavers, Klaas Cuckoo Diederik Cuckoo, Somber Bulbul, Grey Bulbul, Speckled Mouse bird, Ring Necked Doves and many others. 

The vast numbers of tiny greenish yellow flowers are pollinated by various bee species which attract insect eating birds.

Pigeon Wood Trema orientalis flowers

The leaves are also browsed by game animals and can be used as spinach. This tree is a fast growing species found in previously disturbed areas and on forest margins. It is a pioneer species that can grow on poor soil and can be used to regenerate forest areas by providing shade and protection to saplings of forest hardwoods

Trema orientalis is a nitrogen fixing tree which improves soil fertility for other plant species.

From a conventional landscaping point of view Trema orientalis  is not a very suitable candidate for a landscape feature tree because it often looks rather messy due to its leaves being eaten by just about every conceivable insect however it is a must in every garden that strives to encourage wildlife.

Pigeon Wood Trema orientalis leaves eaten by insects

Being a pioneer tree Trema orientalis is very useful when it comes to establishing a new proudly South African garden in particular on poor soils providing shade and a windbreak for other plants that are being established.

Trema orientalis is invaluable when it comes to indigenous forest restoration where it provides shade, nutrients and organic material in the form of dead leaves and vast amounts of excrement from the many insects that feed on its leaves. In addition it provides protection for the slower growing and more tender specimens. Seeds of many trees are also brought onto site by birds which come to feed on the seeds though this may not always be a good thing where undesirable alien plants seeds are brought in by birds feeding on its fruits.
