ROMNEYA COULTERI. 
ROMNEYA. Californian Bush Poppy. R. Coulteri 
(Fig. 652), the only species of this beautiful genns, vy 
described in Vol. IIT. as but half-hardy. It has, however, 
since proved hardy, but it needs a position where it can 
get plenty of sun and a good deep soil. Then it will 
produce its flowers freely, and over a long period—from 
early summer till early antumn. Even near towns we 
have seen it doing well, providing the conditions named 
obtained, and the best plant that we remember was in 
a cottage garden at Croydon. There it was growing 
Inxuriantly, and had attained a height of over 6ft. It is 
a herbaceous perennial of the first water.
