Plant in spring- and mulch around ttic crowns with decayed 
manure annually in autumn. Increased by division of the 
root-stocks in March. 
Romneya (Giant Californian Poppy). — The only species 
is R. Coulteri, and this is a native of California, and belongs 
to the Poppy order (Papaveraceae). It is of a shrubby habit 
of growth, and when grown in a congenial soil and position 
develops into a large bush. The leaves are pinnatified, the 
stems glaucous, and the flowers large, poppy-like in form, 
w r hite and fragrant. It requires to be grown in sandy loam 
in a well-drained, slightly-raised bed or border, in a sheltered 
sunny position. It will not succeed in heavy soils or damp 
cold positions. Growth is sometimes slow for the first year 
or so, but once the plant is established it will grow' and flower 
freely. Plant in spring. In severe w'inters protect the crowns 
by a covering of bracken, litter or leaves. In dry weather 
give water freely. Increased by seeds sown in sandy loam in 
a frame or in slight heat in early spring, afterwards growing 
the seedlings on in pots till the following spring, then planting 
out. Also increased by cuttings of the roots, a safer plan 
than by seeds.
