GOOD HERBACEOUS PLANTS 81 



Rudbeckias. Yellow Daisy-shaped flowers. 

 R. californica flowers in August and September, 

 eighteen inches high, golden flowers, dark centre ; 

 its roots grow very near the surface, so it easily 

 suffers from drought, but is very hardy. R. lacin- 

 atus and R. lacinatus, " Golden Glow," are both 

 about six feet high ; a rich bright yellow, and very 

 effective and handsome, coming in at the same time 

 as the tall Michaelmas Daisies ; they are not par- 

 ticular as to soil so long as they are not allowed to 

 get parched. 



Scabiosa Caucasica is a useful perennial, with 

 large mauve flowers late in the summer, nearly two 

 and a half feet high ; chalky soil. 



Sea Lavender Statice. Wiry flowers almost 

 like Everlastings. S. latifolia is a coarse-growing 

 plant, with large branching heads of lavender 

 flowers in August. 8. incarna is a dwarf variety, 

 with darker coloured flowers in June ; a sandy soil 

 suits them best. 



Solomon's Seal Polygonatum. This graceful 

 plant grows best in moist places, where there is 

 plenty of shade and loamy soil.

with pretty blue or purple flowers, eighteen inches
