166 HAEDY OENAMENTAL 



but observations made in many parts of tbe country 

 conclusively prove that the finest specimens are growing 

 on light, rich loam overlaying a bed of gravel. They are 

 propagated from seed, by layers, or by grafting. 



Romneya (Papaveraceae), 



Eomneya Coultbbi. — Galifornian Tree Poppy. Cali- 

 fornia, 1875. This is sometimes referred to as an herbaceous 

 subject, but as it rarely dies down to the ground, hardly 

 comes within the definition of such, and has of late years 

 been included as a shrubby plant. It is a charming 

 shrub, with large, deeply-cut glaucous foliage, and flowers 

 of a peculiarly delicate texture, pure white with conspicuous 

 yellow stamens. Many of the individual flowers measure 

 8 inches in diameter, and when, as is often the case on 

 established specimens, a dozen flowers are open at the 

 same time, the plant has a charming and beautiful effect. 

 A southern aspect, at the foot of a wall, affords an ideal 

 site for this Eomneya, but it must have an abundant 

 supply of water, while an occasional application of weak 

 liquid manure causes it to send up vigorous shoots from 

 the base, and these shoots produce the finest flowers. It is 

 not at all particular as to soil, and has succeeded well in 

 good loam to which a little peat was added. 



Rosa (Rosaceae). 



Eosa alba. — This is a supposed garden hybrid between 

 E. canina and E. gallica (1597). It has very glaucous 

 foliage, and large flowers, which vary according to the 

 variety from pure white to rose. 



E. alpina (Europe, 1683) grows about a yard high, 

 with doubly serrated leaves, the young stems prickly, and 

 solitary pink or rosy flowers. There are several varieties, 

 including pendulina and pyrenaica.
