ALPHABETICAL LIST OF PLANTS 327 



Leaves grey above, and snow-white beneath. Yellow flowers in 

 the summer. 



P. Tonguei. — Ordinary soil in sunny position. Of trailing habit, 

 growing about 2 inches high. Flowers coppery-orange, with a 

 crimson centre. Not a very free bloomer. This plant should be 

 grown so that its branches can hang over some rock or stone. 

 It is of the easiest culture, and one of the best of the genus. 



P. verna. — Any aspect in ordinary soil. Forms dwarf tufts, 

 which in summer are covered with bright yellow flowers, about 

 I inch across. Quite easy to grow, pretty, and well worth a place. 

 Very closely allied to this plant is P. alpestris^ which is somewhat 

 coarser in growth, and is also a good plant. 



Pratia angulata (Campanulaceae), syn. Lobelia 



LiTTORALIS 



A pretty, creeping plant, indifferent to soil or aspect. It forms 

 a dense carpet, about 3 inches high, covered, in late summer, with 

 white flowers like a Lobelia, and followed by dark blue berries. 

 Of easy culture, and readily increased by division. 



P. begonifolia, — Likes rather a sheltered, sunny position in 

 damp, peaty loam. Rather similar to the above, but has larger 

 and rounder leaves, which are downy. White flowers and purple 

 berries. Suitable for the drier parts of the bog garden. 



Primula (Primulaceae) 



This very large genus of well-known plants, of which there are 

 over two hundred species in cultivation, have botanically been 

 divided into twenty-one sections ; but, for our purpose, it will be 

 sufficient to separate them into three groups. The first, the rock- 

 loving kinds, such as P. auricula and P. ma7'gmata^ which 

 should be grown wedged between stones, or in rocky crevices. 

 Next, the bog and moisture-loving plants, of which P. japonica 

 and P. sikki7nends are well-known types ; and lastly, those that 

 can be grown in any moist, shady border, which include such 

 species as P. cashmeriana and P. capiiata. 



As might be expected in a genus containing so many species of 

 such diversity of habit and requirements, it is not possible to deal 

 with their cultural requirements as a whole, but directions will be 

 given with each as they appear in alphabetical order. The kinds 

 described in the following pages only contain about a quarter of the 

 known species, and are a selection of the most suitable and of easiest 

 culture, it being obviously impossible in a work of this kind to 

 give anything approaching an exhaustive list, nor would it indeed
