proper. All easily increased by division after 
flowering is over in early summer, or from seeds. 
ARGEMONE grandiflora. — This Prickly Poppy from 
Mexico, although really a perennial, is best treated as a 
half-hardy annual. It has ornamental blue-green, 
poppy-like leaves with irregular spiny-toothed mar- 
gins, and during the summer months produces large, 
snowy-white flowers, with a bunch of golden-yellow 
stamens in the centre. It grows 2 to 3 feet high, and 
flourishes in ordinary good garden soil, in a warm 
sunny spot. It is raised from seeds sown in gentle 
heat about March. Other species are albiflora and 
hirsuta , with white flowers ; and mexicana (Devil’s Pig) 
and ochroleuca with yellow ones. 
ARMERIA ( Thrift . Sea Pink). — The Thrifts are 
excellent plants for edgings, or for making evergreen 
grass-like tufts in the rock garden or border. The 
hardy kinds thrive in ordinary well-drained soil, and 
are easily increased in spring or early autumn by 
division. Seeds may also be sown, but are scarcely 
worth the trouble. When the flower heads appear 
above the deep green foliage, the plants are then more 
highly effective than ever. The best kinds are alpina, 
and its variety rosea, with pale and deep rose flowers ; 
hracteata rubra, bright crimson ; cephalotes (or latifolia ) 
rose, and its white variety alba, the red one (rubra) 
with flowers on stalks about 18 inches high ; csespitosa, 
pale-lilac, very dwarf ; juiicea rosy-pink ; maritima, 
pink or rose, and its varieties ; Laucheana, bright rose ; 
alba, white ; Crimson Gem, bright crimson ; and Ewart, 
crimson-purple ; plantaginea, bright rose, and its 
variety splendens.
