224 ROCK GARDENING FOR AMATEURS 



are E. Sibthorpii and E. Wulfeni. A pretty little plant 

 is the Cypress Spurge (E. Cyparissias) , widely distributed 

 in Britain, with evergreen foliage and bright yellow in- 

 florescences in spring. It is useful for planting on shady 

 banks, where it will soon spread. Perhaps the most 

 attractive of all is E. epithymoides. This grows about 

 eighteen inches high, forming quite a bushy plant, covered 

 with heads of bright yellow bracts in spring. These change 

 to a rosy-bronze colour with age. One of the dwarfer 

 kinds is E. Myrsinites, native of South Europe, with 

 prostrate or trailing stems and glaucous leaves, while 

 similar, but with erect stems, is E. glandulifera, which 

 flowers during the winter. All the Euphorbias are easy 

 to grow in any light, well-drained soil. Owing to the 

 long roots they make, several are difficult to transplant, 

 and take some time to recover. Plants may be raised 

 from seeds sown in spring, potted off singly in sandy loam 

 when large enough, and planted out when the pots are 

 full of roots. E. epithymoides may be divided, but care 

 must be taken that some roots remain on each separated 

 piece. 



Frankenia (Sea Heath) Frankenia laevis (natural 

 order Frankeniaceae) , which is chiefly grown, is native of 

 South and South- West maritime Europe, and is found 

 in the south-eastern counties of England. It is a small, 

 prostrate, evergreen plant, and bears, in July, tiny pink 

 flowers. It is happiest in a shady spot, and in a soil 

 composed of half peat and half sandy loam. 



Fritillaria. See Bulbs for the Rockery.
