252 ROCK GARDENING FOR AMATEURS 



It is of less straggling growth than the former, and 

 bears rose-pink blossoms in June. Propagation is by 

 seeds sown in spring or summer, or by cuttings taken 

 after flowering; the latter are inserted in sandy soil 

 and kept in a closed frame. 



Schizocodon soldanelloides. Only one species of 

 Schizocodon (which belongs to the natural order Diapen- 

 siaceae) is in cultivation. It is native of Japan, the 

 flowers resemble those of Soldanella (which see), and the 

 plant needs similar treatment to the Shortias, to which 

 reference is made on the next page. 



Senecio (Groundsel). Very few of the Groundsels, 

 which belong to the Daisy family (Compositae), are of 

 value for the rock garden, but mention may be made 

 of Senecio argent eus, a small Pyrenean plant, with silvery 

 grey leaves, for which, indeed, it is chiefly valued, and 



bearing yellow 

 blooms in June.

 S. uniflorus,
