82 About Trees, Shrubs and Climbing Plants for S.A. 



Gardenias Gardenia florida is well known and popular. Its large 

 pure white, heavily scented flowers are freely produced from 

 September to almost Autumn, and are well set amongst the 

 dark green foliage. 6 feet. Gardenia thunbergii and G. 

 globosa are indigenous to South Africa and make much larger 

 trees, in some cases 20 to 25 feet high. The former has large 

 star-shaped flowers, while the flowers of the latter are bell- 

 shaped. Both are sweetly scented. 



*Galphimia nitida A small shrub (5 feet) bearing many yellow 

 flowers. Suitable for warm districts only, or sheltered spots. 



*Genista scoparia The common " Broom " of Europe. The 

 flowers are very abundant and showy. 4 feet. 



Orevilleas G. robusta, the Silky Oak, is one of the most beautiful 

 of large ornamental trees, the fern-like leaves being quite 

 an unusual form. In September great masses of dark yellow 

 inflorescence cover the branches. On the high veld it is 

 only suitable for sheltered positions, but we have seen it 

 doing well at Johannesburg. 50 feet. G. caleyi, the red- 

 flowered Grevillea, is a dwarf tree of 10 feet, and much 

 hardier. Flowers are somewhat similar to the " Bottle 

 Brush " and very gorgeous. 



Gr cilia suthcrlandii Native to Natal on the edges of bush. 

 Flowers of "bottle brush" form and a brilliant crimson- 

 scarlet. 8 feet. 



fJamclia rhrjiftanlha Dwarf and somewhat tender. Corymbs of 

 bright yellow flowers, erect on the end of the branches. 3 

 feet. 



Harpephyllum cafrum (The Kafir Plum) Indigenous in East 

 coast bush. A fairly large tree (40 feet), with handsome 

 pinnate foliage. For warmer districts. 



Heliotrope* sometimes form good sized bushes in the front shrub- 

 berv border, but s>re susceptible to cold. In a warm corner 

 under the house sides, or where sheltered by trees, they will 

 still do well in even cold districts. 2 to 4 feet. 



Habrothamus. See Cestrum. 



Hibiscus syriacus See Althea. 



Hibiscus One of the most gorgeous of all flowering shrubs and 

 in warm situations will make a small tree with a wide spread. 

 There are several colours, ranging from pale yellow through 

 pink to dark crimson and scarlet, all with very large and 

 showy flowers. In the cold districts the frost will often cut 

 back the young succulent growth, but this quickly re-grows, 

 and every young shoot will bear a flower. The best are H. 

 lambertii, double crimson; miniatus, double crimson scarlet; 

 rosa sinensis, single pink, and rosa sinensis fulgida, single 

 crimson. H. cooperii, a small growing form, with green and 

 pale yellow foliage, is grown for foliage effect only. 10 feet. 



UHriftcus mutabilis Is deciduous, even as low down as Maritz- 

 burg. The flowers are large rosettes, opening white, and 

 changing to a delightful rose tint. 10 feet.
