Oxytropis uralensis (Europe, Scotland). 
Treat like Oxytropis Lamberti. 
Papaver alpinum (Alps). 
A useful plant for the small rockery, growing 
anywhere on it in sandy loam. A little seed 
scattered amongst the rocks will soon germinate and 
produce a good effect when the Poppies are in bloom. 
Pelargonium Endlicherianum (Taurus). 
The only hardy species known. Grow on the 
sunniest and driest part of the rockery, wedged 
tightly between stones, in a compost of limestone and 
strong loam. Through the winter a stone should be 
laid over the place where the plant is, as a protection 
against the cold rains. 
Pentstemon glaber (Western United States). 
Plant in a well-drained position, shaded from the 
midday sun if possible, on the flat, in loam, leaf- 
mould, and grit. In early spring the old foliage 
should be cut away before the young growth starts 
about its base, as otherwise the old shoots are apt to 
be twisted about by the wind and the tender young 
ones destroyed, and so the plant perishes. 
Pentstemon Hallii (Rocky Mountains, Colorado). 
Requires the same treatment as Pentstemon 
glaber, except that in consequence of its different 
habit it should receive a top-dressing each spring and 
autumn with a little grit and leaf-mould worked well 
among the foliage, as it is apt, like Aster alpinus, to 
form little hard stems and grow out of the ground 
unless this is done.
