274 ROCK GARDENS 



Of close, prostrate, creeping habit, free-growing, and forming a carpet 

 of dark green leaves, which in winter turn brown, looking as if the 

 plant had died. Large creamy-white flowers, with yellow stamens 

 like the Burne: rose. Profusion of blooms in summer, followed by 

 fluffy-headed seed-vessels, hke those of the " traveller's joy " clematis. 

 A native, and quite hardy, and of easy culture. Increased by layers 

 and seed. One of the gems for the rock garden, which should be 

 freely grown, not alone on account of its flowers, but also for the 

 fluffy seed-vessels. 



The variety minor is dwarfer and more dense in growth ; also a 

 treasure. 



D. Dru?n?nondn. — Requires same treatment as above, which it 

 exactly resembles, except that it has pale yellow flowers, which, 

 however, have the reputation of not opening. 



D. tenella is a rare species from Labrador, rather similar to 

 octopetala. 



Edrianthus {see Wahlenbergia) 



Empetrum Nigrium (Empetraceae), Crowberry 



Dwarf evergreen shrub, growing about 12 inches high. Like a 

 heath, it has black berries. Rubrum has red berries. Both of 

 easiest culture in damp, peaty soil, and may be used with the 

 dwarfer shrubs. Evergreen. 



Epigaea repens (Ericaceae) 



A small, trailing evergreen shrub. Requires shelter from cold 

 winds in a shady position, in peaty, fibrous loam and sand. Very 

 pretty, fragrant, rose-coloured flowers in terminal racemes in early 

 spring. Difficult to grow. Grows wild in parts of North America 

 in sandy, rocky soil, under the shade of pines. 



Epilobium (Onagraceae), "Willow Herb" 



Few of this genus are suitable, being generally of too coarse and 

 rank a growth. Increased by seed and division.

 shrubby habit, with rosy-red flowers in July. Pretty and useful, 



E. nu?n?nularifolm?n. — Of creeping habit and very rapid growth. 

 Pale pink flowers. As it spreads rapidly, it should be given plenty 

 of room. 



E. obcordatum. — Also of creeping habit and rapid growth. 

 Cherry-pink flowers. Looks well planted to fall over a stone. 

 Requires a moist, well-drained spot.
