place for summer blooming. It bears its Q-inch spikes 

 of purplish mauve flowers in July. There are white 

 (alba) and red (rubra) varieties. Ordinary soil. Propaga- 

 tion by division in spring. 



PULMONARIA (LUNGWORT). There are two very 

 pretty varieties of angustifolia, the " Blue Cowslip " : 

 azurea, with dark blue, and rubra, with rosy salmon 

 flowers. Late spring bloomers, they grow six to nine 

 inches high. Saccharata is a distinct species, with pink 

 flowers ; the leaves spotted with white. Ordinary soil. 

 Propagation by division in spring. 



RAMONDIA. Pyrenaica and its white variety are 

 both suitable for the rock garden ; there is also a rose 

 form, rosea. 



RANUNCULUS. In a moist spot at the base of the 

 rockery several of the Ranunculuses may be grown, 

 while others, notably aconitifolius flore pleno (" Fair 

 Maids of France ") and acris flore pleno (" Bachelor's 

 Buttons "), are good for the border. Amplexicaulis, 

 white, one foot high, flowering in May ; gramineus, 

 slender, grassy, grey leaf, large yellow flowers on 8-inch 

 stems ; parnassifolius, white flowers ; and montanus, 

 yellow, may be grown in the cooler parts of the rockery. 



RHODODENDRON. The small Alpine species are 

 good plants. The most interesting is intricatum, a tiny 

 plant introduced from China by E. H. Wilson, only 

 growing six inches high, with minute leaves and small 

 mauve flowers. Ferrugineum is the Alpenrose, and has 

 rosy flowers in terminal clusters ; there are several 

 varieties, including major, large ; alba, white ; and 

 latifolium, broad-leaved. Hirsutum, red flowers, is the 

 hairy Alpenrose ; there is a form of it called marginatum.
