it is a climber, growing 6rt. high, and is very suitable for growing 

 over arches, over the sides of flower-boxes, &c. It is also known 

 as T. pereg7'imim and T. admiciun. T. Lobbiaitum is a superb 

 climber, flowering more freely on a poor dry soil There are 

 several named varieties, differing only in the colour of their 

 flowers ; all are graceful climbers, bearing a great profusion of 

 blossom, in rich and brilliant colours. They are suitable for cover-

 Cress) (Fig. 143) is the species from which the numerous forms 

 of Tom Thumb Nasturtiums have originated. Few plants are so 



useful or rich in colour 

 as these Nasturtiums, for 

 in dry soils they surpass 

 the Geranium and Cal- 

 ceolaria in brilliancy of 

 colour and profusion of 

 flower. Seeds may be 

 had either in named 

 varieties or in mixed 

 colours. All the 

 annual Trop^olums 

 may be easily raised 

 from seed sown in 

 the open ground in 

 April, or in pots under 

 glass, the young plants 

 being gradually hardened 

 off and planted out about 

 the beginning of June, 

 when they will soon 

 commence to flower and 

 will keep on until October. 



Waitzia aurea (Fig.

 bright yellow flowers in 

 loose corymbs during the 

 summer. It grows about 

 I ft. in height, and is 

 sometimes called Morna 

 nitida.

 fusion ; for filling flower-beds and borders, and for cutting, few 

 flowers are more useful. The seed should be sown in a gentle 

 hotbed in March or April, pricking out the seedlings into frames,
