shoots are very apt to get pulled off, and thus the 
whole plant is often destroyed. When planted out 
on the flat, where the subsoil is damp and clayey, a 
place should be specially prepared for it as follows :— 
First, make a hole 2ft. wide and 18in. deep ; put in 
4in. of drainage, then add a few inches of rough loam, 
and fill up to the ground level with pure river sand, 
finally planting in the centre of the plot. When 
treated in this way, the plant will live for years, and 
increase and flower freely. 
OEnothera missouriensis, syn. macrocarpa (N. America). 
Plant in a well-elevated position, where the long 
shoots will hang over the face of a rock, in deep 
poor loam. As this species is of somewhat 
straggling as well as strong growth, it should be 
planted in a somewhat confined area where it is 
cramped in with stones. In late autumn a top- 
dressing of grit round the old stool prevents any 
decay through wet during the resting season. In 
winter the old growths may be entirely cut away, as 
the plant will spring anew from the base; indeed, 
many of the shoots may be removed without detri- 
ment, even when in full vigour. 
QEnothera rosea (N. America). 
This affords a most desirable plant for a promi- 
nent place on the rockery in’ autumn if the true 
species be obtained. Plant on the flat in a well- 
drained position at the base of a rock-wall facing 
full south, where it will have plenty of room for its | 
free growth and will be perfectly dry in winter, in 
deep loam and sand.
