The European and Asiatic Globe Flowers (Trollius, Fig. 16), 
glorified buttercups of moist alpine meadows, are, with the ex- 
ception of such dwarfs as 7. acaulis and T. pumilus, too robust 
for the small rock garden. We grow large patches of 7. astaticus 
and T. curopeaus in a low moist place where their yellow flowers 
form a pleasing contrast with the blue of Veronica Teucrium, 
planted nearby.
