Knowltonia vesicatoria (Brandblaar) is an attractive, shade-loving plant of the family Ranunculaceae, that is indigenous to the southern parts of South Africa.
This is one of at least ten species of Knowltonia that are native to South Africa. Knowltonia vesicatoria can be told apart from the other species by its leaves and stems being hairless, and by the slightly jagged, toothed margins of the leaves. It in turn has three subspecies: vesicatoria, humilis and grossa.
This slow-growing plant forms clusters of dark green leaves on the forest floors where it grows. It produces white or yellow flowers in spring and then clusters of fleshy black fruits. A tough and adaptable plant that easily survives seasonal fires, Brandblaar grows in shady spots in Cape Fynbos, along the coast, in afro-montane forest and just about anywhere else - throughout the Cape Floristic Region, from Cape Town eastwards as far as Grahamstown.
Further east - in the Eastern Cape and Kwazulu-Natal - this plant's close relative Knowltonia capensis is rather more common.
This is an ideal plant for shady spots in gardens. It grows very slowly but once established it is tough and attractive, and survives deep shade where other plants would die. It grows much faster if it is watered regularly, and should be allowed to establish itself, free from competition from faster-growing groundcovers. It can easily be propagated by seed. [1]
Curtisia dentata is a flowering tree from Southern Africa. It is the sole species in genus Curtisia, which was originally classed as a type of "dogwood" (Cornaceae), but is now placed in its own unique family Curtisiaceae.
Vachellia karroo, commonly known as the sweet thorn, common acacia, Karoo thorn, Cape gum or cockspur thorn, is a species of Vachellia, in the Mimosa sub-family (Mimosoideae) of the Fabaceae or pea family, which is native to southern Africa from southern Angola east to Mozambique, and south to South Africa.
Podocarpus henkelii is a South African species of conifer in the family Podocarpaceae. It is grown ornamentally in gardens for its strikingly neat, attractive form and its elegant, drooping foliage.
Ochna serrulata is an ornamental garden plant in the family Ochnaceae which is indigenous to South Africa. It is planted in southern African gardens and is an invasive species in Australia and New Zealand.
Brabejum is a genus of a single species of large evergreen tree, Brabejum stellatifolium in the family Proteaceae, commonly called wild almond, bitter almond or ghoeboontjie. It is restricted in the wild to South Africa's Western Cape province, where it grows in thickets along the banks of streams. The plant is of botanical interest as being Africa's only member of the large grevilleoid subfamily. It is a bushy small tree with branches widely at ground level and numerous erect vigorous stems. Leaves grow up to 6 in (15 cm) long, narrow and bluntly toothed, appear at intervals along the branches, mostly in whorls of 6. In summer, the plant bears white flowers densely crowded on spikes arising from rusty buds at the leaf axils. The fruits to 2 in (5 cm) long, magenta to reddish brown, similar to an almond, appear in autumn. The nut is too bitter to eat; however, in earlier times it was boiled, roasted, and ground to make a "coffee" drink.
Asparagus scandens is a flowering plant native to South Africa in the genus Asparagus. It is not related to ferns.
Aloe perfoliata, the rubble aloe or mitre aloe, is a hardy creeping aloe, found in rocky, mountainous areas throughout the Western Cape, South Africa.
Diospyros whyteana is a small African tree of the ebony family. Bearing dark green, strikingly glossy leaves and creamy fragrant flowers, it is increasingly cultivated in Southern African gardens as an attractive and strong ornamental tree. It can attain a height of up to 6 m.
Kiggelaria africana is a large, robust, low-branching African tree, and is currently the only accepted species in the genus Kiggelaria.
Halleria lucida is a small, attractive, evergreen tree that is indigenous to Southern Africa. It is increasingly grown as an ornamental tree in African gardens.
Podalyria calyptrata is a small, resilient, fast-growing tree of the Fabaceae (legume) family. It has velvety silver leaves, bears masses of bright-pink, sweetly scented flowers, and is indigenous to the Western Cape, South Africa.
Apodytes dimidiata is a bushy tree with white flowers bearing a fragrance reminiscent of fresh coconut, and small black and red fruits. It is usually about 5 m tall, and it is indigenous to Southern Africa. The taxonomical family placement for this and other Apodytes was uncertain; it is now placed in the Metteniusaceae. Its English common name is in reference to the timber which is similar in appearance to that of the European pear tree of the northern hemisphere.
Cassine peragua, also known as Cape saffron, bastard saffron and forest spoonwood, is a medium-sized tree with fragrant flowers, decorative fruits and a saffron-coloured trunk. It is indigenous to the Afro-montane forests of South Africa.

Rhoicissus tomentosa is a vigorous, evergreen vine that is indigenous to the afro-montane forests of southern Africa. It is increasingly popular as an ornamental creeper in gardens, and it has a wide range of uses in traditional medicine.
Knowltonia capensis (Brandblare) is an attractive, shade-loving plant of the family Ranunculaceae, that is indigenous to the Cape and Kwazulu-Natal regions of South Africa.
Asparagus falcatus is a large, thorny, climbing plant of the Asparagus genus, that is indigenous to South Africa and Mozambique. It is often grown as a security hedge in southern Africa.
Xanthomonas campestris pv. vesicatoria is a bacterium that causes bacterial leaf spot (BLS) on peppers and tomatoes. It is a gram-negative and rod-shaped. It causes symptoms throughout the above-ground portion of the plant including leaf spots, fruit spots and stem cankers. Since this bacterium cannot live in soil for more than a few weeks and survives as inoculum on plant debris, removal of dead plant material and chemical applications to living plants are considered effective control mechanisms.
Gasteria polita, the polished gasteria, is a recently discovered succulent plant restricted to a locality in the Afro-temperate forest of the Western Cape, South Africa.
