Potentilla nitida and vars. (S. Europe). 
These are purely rock plants, which should 
be planted on an elevated piece of ground with 
either a south or south-west aspect, on the flat or 
between stones, in equal proportions of grit, leaf- 
mould, and loam. While, however, an elevated 
position is chosen for these plants by preference, 
yet the site selected should not be so high above 
the path or so far from the path edge that the 
beauty of the flowers or of the dwarf plants which 
bear them is lost or obscured. Once or twice in 
the year, top-dress with a portion of fine grit run 
among the leaves and stems, as otherwise the 
plant will grow out of the ground and die. 
Potentilla nivalis (Pyrenees). 
Treat like Potentilla nitida. 
Potentilla: Remaining species. 
The other species of Potentilla are all of very 
easy culture in sunny places. 
Pratia angulata (New Zealand). 
This makes a beautiful carpet plant. It should 
be grown in a sunny position, on the flat, facing 
south or south-west, in sandy loam with a little 
leaf-mould. As the plant is of a creeping habit, it 
should be pressed down perfectly flat when planted. 
Pratia angulata will also grow well in shade, 
although it does not then flower so freely Two 
or three times a year, top-dress with sand and a 
little fine leaf-mould, not covering the plant too 
thickly, on account of its very fine stems.
