ALPHABETICAL LIST OF PLANTS 277 



E. trifidus. — Small blue flowers. Dwarf habit, only growing 3 to 

 4 inches high. Rather a distinct plant. 



Of the taller-growing kinds, the following are all good : — 

 E. glabellusy lilac flowers ; E. salsuginosus^ pale lilac flowers ; 

 and E. speciosus splendens^ with deep lilac-coloured flowers. 



Erinus alpinus (Scrophulariaceae) 



A pretty little plant, admirable for growing in old walls and in 

 any odd chink, or for crevices between steps. Forms very dwarf 

 tufts of downy, toothed leaves. Rosy-purple flowers in racemes the 

 whole summer. There is a white form, and also a very hairy 

 form, hirsuta. 



Eriogonum umbellatum (Polygonaceae) 



Small shrubby plant. Requires a sunny position in sandy loam. 

 Forms a dense, spreading tuft, with numerous yellow flowers in 

 umbels, borne on stems 4 to 8 mches high. Quite hardy, and 

 blooms profusely during the autumn. Seed or division. 



Eriogynia Pectinata 



A distinct plant, nearly allied to the Spiraeas. It is an evergreen 

 of traihng, tufted habit, spreading by means of slender stolons. 

 Bright green, ferny foliage. White flowers in terminal spikes. 

 Likes a shady corner in good sandy loam. A pretty little plant. 



Eritrichium Nanum (Boraginaceae) 



An alpine gem, which so far has defeated all efforts to cultivate 

 with any degree of success. Its needs, though few, are difficult to 

 supply. No moisture during the winter, while during the spring 

 and summer it requires moisture at its roots, but none on its leaves. 

 This, though it may sound simple, is not so easy to supply. The 

 following method may be tried. Plant in a mixture of coarse 

 sand, grit, and granite dust, and a little fibrous peat, under some 

 overhanging rock fully exposed to the sun. Round the neck of the 

 plant sink pieces of slate in such a way that the moisture from the 

 overhanging ledge is directed towards the roots of the plant, and 

 also place stones on the surface of the ground to keep its leaves 

 dry. It makes tufts of tiny little woolly leaves, from which in 

 spring rise, in the greatest profusion, diminutive flowers of the most 

 dazzling azure-blue, with a yellow eye. A gem indeed, and worth 

 any amount of trouble to obtain success.
