Spectacular Monthly Tree - December 2012

Spectacular Monthly Tree

Although we have many tree species at our nursery that are looking spectacular at any given time, we feature just one tree in particular every month that we know will offer you the best value for money and that will add that special touch to your landscape project.

Podocarpus henkelii is undoubtedly the best yellowwood species for confined urban areas and for the garden. The characteristic narrow, drooping, dark green leaves and the attractive conical shape make it one of our loveliest indigenous trees. In the forest, these decorative trees will grow to a height of 30 meters but in the open, they will grow more slowly and reach a height of about 10 meters. These popular yellowwoods will also grow well in large containers which can be placed in semi shaded positions on patios or other paved areas.

Because Podocarpus henkelii has such a lovely shape, they make perfect indigenous Christmas trees. Whether you have large specimens in the garden or more compact ones in tubs, they look stunning when decorated with lights and Christmas ornaments.

We have really beautiful, large specimens in stock so hurry and get yours now to avoid the Christmas rush.

The Distinctive Umbrella Thorn

There are few images that are more symbolic of the South African savannah and indeed, the African continent, than the iconic form of the umbrella thorn (Acacia tortilis subs heteracantha).

The blue - black silhouette etched against a burning African sunset, standing as a sentinel on an arid plain or looming out of the early morning mist, speaks it’s own silent poetry, appealing not only to the mind but also to the heart of all who behold it.

Listed as one of the Big Five most photogenic trees of the Kruger National Park, the umbrella thorn provides a bounty of nourishment and shade for man and beast alike while the wood, bark and roots have benefitted countless generations of people throughout the continent.

These fantastic, sculptural trees can reach a height of 20 meters while the dark, gnarled branches can achieve an impressive spread of up to 13 meters.

The name Acacia is derived from the Greek word ‘akis’ meaning pointed or barb while the Greek word ‘tortilis’ means twisted, referring to the spiral shape of the pods. The word ‘heteracantha’ means different thorns alluding to the straight as well as the hooked thorns that are found on the umbrella thorn.

Wherever the traveller encounters this remarkable symbol of Africa, the sight is bound to leave an indelible impression on the memory, of beauty, dignity and the ongoing rhythm of life that the umbrella thorn represents.

Chionanthus foveolatus (Pock ironwood)

Each month, our readers look forward to our featured tree review. We conduct in-depth research into each species, to obtain as much information as we possibly can in order to offer you a truly valuable, expansive information resource. All the trees we feature are indigenous species which are suitable for use within commercial and residential landscaping projects and are easily grown throughout most of Southern Africa, but specifically the Western Cape.

The tough Chionanthus foveolatus, an attractive member of the olive family, is an asset to any landscape with its silvery grey, slender trunk, bushy crown and neat habit. Add to this the delightfully fragranced flowers and the striking, glossy, deep purple fruit and you have a tree that is perfect for any number of situations. The sweetly fragranced flowers attract bees and insects while many bird species delight in the fruit. Although the Pock ironwood occurs naturally along the South African coastline, these undemanding trees can be grown successfully throughout the country as they adapt easily to a wide range of soil and climatic conditions.

Spectacular Monthly Tree - November 2012

The magnificent, tall, Celtis sinensis is often mistaken for our own stinkwood but differs from the stinkwood in various ways. The leaves of the Chinese hackleberry are covered with coarse hairs while the tips are more tapering and the marginal teeth are larger. These imposing deciduous trees have a wide spreading crown creating lovely dappled shade in summer while the pale grey of the bare branches add an interesting dimension to the winter garden.

The flowers that appear from spring to early summer attract bees while the bright orange berries that cover the tree in autumn are relished by birds.

Because of their attractive growth habit, these beautiful trees have long been used as an ornamental feature in East Asian classical garden design.

The King Edward vii Yellowwood

Estimated to date back to around the year 1350, the King Edward vii Outeniqua yellowwood (Podocarpus falcatus), in the forest at Diepwalle forestry station between George and Knysna, is generally believed to be the largest of several monumental specimens of this species in the country.

In 1924, during a visit by the British Parliamentary Association, the tree was given the name “King Edward vii” as the delegation, awe inspired by it’s magnificence, were served lunch under the tree.

Surrounded by a thick carpet of ferns and towering to a height of 39 meters, this 662 year old wonder of the forest was originally known as Templeman’s tree.

A story is told that a woodcutter by the name of Templeman bought the tree but, as the tree was so immense, in fact much too large for a woodcutter of that time to deal with, he fortunately never cut it down.

The dimensions of this majestic leviathan are almost unbelievable. The circumference of the trunk, measured at a height of 1.30m from the forest floor is 7 meters while the length of the trunk is 22 meters and the spread of the crown, an amazing 31.5 meters.

Today, as the wind rustles through the leaves and the old man’s beard wafts gently from the branches, this imposing giant enthrals all who have the privilege of walking the trail from Diepwalle forestry station to view this massive, noble example of the Outeniqua yellowwood.

Loxostylis alata (Tarwood)

Loxostylis alata is such a decorative and versatile tree that it really deserves to be used far more extensively. This medium sized, water-wise evergreen has a lovely shape and looks absolutely gorgeous when the beautiful sprays of white flowers appear. As the fruit begins to develop the sepals around the fruit turn deep pink creating a stunning display. Aside from being extremely showy, the Tarwood attracts butterflies, bees and insects which in turn attract many birds to the urban landscape. Loxystylis alata does not make a mess, has non invasive roots, is highly ornamental and can tolerate harsh dry, windy conditions making it an ideal, low maintenance all rounder.

The changing colours and attractive form of the Tarwood ensures that it will create an eye catching focal point in any landscape as well as providing welcome shade on hot summer days. These delightful trees are ideal for creating a dense screen where privacy is needed as well as forming a formidable windbreak in coastal areas where strong, salt laden winds, harsh sunlight, sandy soil and dry conditions prevail. As more and more people opt for small, low maintenance gardens, Loxostylis alata is a wise choice as these trees are the perfect size for more confined areas while their tidy habit makes them ideal for providing shade on patios and for parking areas. As they are able to withstand harsh growing conditions, Tarwoods are perfect for public areas as well as for street planting.

The Saffron Pear of the Company Gardens

Every spring an ancient tree in Cape Town’s Company Gardens covers itself with beautiful white blossoms to herald in the new season.

The noble old Saffron pear (Pyris communis) was brought to the Cape from Holland in the time of Jan van Riebeeck when the gardens were in the process of being established by master gardener, Hendrick Boor.

The gardens were originally established as a fruit and vegetable garden to provide supplies for ships calling at the Cape and were later expanded to include an herb and medicinal garden.

Later however, ornamental trees and plants were introduced and the old Saffron pear was the first ornamental tree to be planted in the garden making it the oldest cultivated tree in South Africa.

The original trunk of this magnificent tree eventually succumbed to old age and the four large stems that you see today are suckers that arose after the main trunk died.

In order to preserve this historic icon, major maintenance work was done on the Saffron pear in 1980. This consisted of removing all decomposed material from the four trunks and then treating the cleaned areas with a special sealant. Metal supports were then attached to the trunks to prevent any further damage from the elements.

Many visitors who value the history, peace and beauty of the magnificent Company gardens, spend some time to marvel at the wonderful old Saffron pear and reflect awhile on the 362 years of momentous events that this dignified old tree has survived.

Pittosporum viridiflorum (Cheesewood)

These delightful trees are irresistible to insectivorous birds when the sweetly fragrant flowers appear, along with a host of insects, while a wide variety of seed eating birds such as the red eyed dove, flock to the tree when the startlingly bright red seeds appear. Selected as one of the Trees of the Year 2002, Pittosporum viridiflorum is a truly excellent all rounder and is becoming increasingly popular as a garden and street tree throughout the country.
