perennial which may be grown in the ordinary herba- 
ceous border in light rich soil and can be increased by 
seeds, cuttings or divisions. It also proves a useful 
denizen of a half-shady patch in the Rock Garden, where 
it may be expected to flower freely during the months of 
spring and early summer. The material for our plate was 
obtained from a plant so grown which had been obtained 
for the Kew collection by purchase in 1907,
