Alkanna tinctoria (Europe, Orient). 
An almost extinct species, extremely rare in 
gardens. Since it requires to be kept as dry 
as possible during winter, while it will stand 
abundance of water during the growing season, 
plant on the south of rockwork, under a stone 
which hangs over from the north, in a deep 
sandy loam, plenty of room being left for the 
tap-root to descend among the rocks, as then the 
plant, when well established, will stand any amount 
of burning in summer. In spring top-dress with 
sand, taking care to keep the top-dressing away 
from the neck of the plant as it requires freedom 
in that quarter.
