8 Alpine Plants. 
a top-dressing of sandstone should be worked well 
among the foliage if this plant is to be kept from 
damping off. 
Achillea Clavennz (Austria). 
Plant on the flat in full sun facing south, in 
deep loam. When the leaves fall after flowering, 
before the plant goes to rest, it must be top-dressed 
with equal parts of loam and sand or it will be lost. 
Achillea Herba-rota (France). 
Treat like Achillea Clavenne. 
Achillea Huteri (Switzerland). 
The bright green foliage and pure white flowers 
of this plant make it useful. It grows well on a 
sunny part of the rockery, in common sandy loam. 
Top-dress once or twice in the year, otherwise the 
stems may grow loose and the wind blow off the 
young growths. 
Achillea rupestris (S. Italy). 
A pleasing and early flowering kind, of very 
easy cultivation. Does well in a full south aspect, 
in very sandy soil, with a little limestone added 
when possible. The foliage of this plant often turns 
brown in early autumn, so that it appears dead or 
in a dying state. This rusting may be prevented 
and free growth induced by top-dressing with a 
mixture of grit and leaf-mould worked among the 
shoots immediately after the plant has ceased to 
flower.

Plant, facing full south, in poor sandy loam. 
About every second year, when the plant becomes
